He can be summon by any party member and can either participate in the fight or wipe out a horde of non-boss enemies.

Other Characters/Non-Playable Allies
Most of these characters appear at the beginning of the game while some will appear after you unlock other playable characters.

Main Villains

Some of these boss fights requires you to have a specific playable character.

Gebel (Bloodstained: Ritual of the Night): He's the leader of a group of villains and is the most powerful of the four Elite of Darkness. His desire is to spread despair and misery upon the world. He is the final boss in his Castle. I imagine his fight to be similar to Dracula from the Castlevania series.

Ashtar (Ninja Gaiden 2 NES): The second Elite of Darkness and Gebel's second in command. He is powerful with his sword, the Chaosium Sword and commands a variety of powers such as flight, teleport, and fireballs. He is one of the final boss in Gebel's Castle.

Regent of the Mask (Ninja Gaiden 3): The third Elite of Darkness and is Gebel's technician on weaponry and magic. He is a skilled swordsman, martial arts, and can cast powerful magic such as Illusions and Curses. He is one of the final boss in Gebel's Castle.

Esdeath (Akame Ga Kill): The fourth Elite of Darkness. She's a skilled swordsman, can create ice at will, and can even stop time temporarily. She is one of the final boss in Gebel's Castle.

Kurome (Akame Ga Kill): Akame's sister and a returning character. She joined Gebel's group after the last game. She still has the same attacks. In one event, she summons a creature named Desta-Ghoul as a sub-boss. In addition to being one of the final boss in Gebel's Castle, she also summons Natala and Doya in the fight.

Note: Akame must be first in you party in this final boss.

Kuroka (High School DxD): She is Koneko's sister and joined Gebel's group. Unlike her sister, she is an expert on Senjutsu and Youjutsu. She's been observing you soon after you defeat a "specific" boss. She is fought twice (mostly to see if you've improved) and is one of final boss in Gebel's Castle.

Note 1: Koneko must be first in your party in this final boss.
Note 2: Kuroka is actually undercover for Vali.

Doomsday (Superman): He was found from another dimension by Regent of the Mask and sent him on a rampage. He is fought twice: The first fight is a test of what Doomsday can do while being observed by Kuroka. The second fight, however, you must stall him while Momonga cast a spell to send Doomsday back to the another dimension.

Note: Momonga must be in your party in Doomsday second fight.

Selvaria Bles (Valkyria Chronicles): A member of Gebel's group and Esdeath's Right-Hand soldier. She attacks with her ragnite spear and shield. She is fought three times. Like Kuroka, Selvaria faces you twice to see how you've improved. When you defeat her a third time, you will gain a key, which access to Gebel's Castle.

Martis (Yugioh Forbidden Memories): A member of Gebel's group and the first of the group you face. Before you face him, he will summon two large golems to protect him.

Thadeus Harlan (Thief): A hunter for hire. He was hired by Gebel and seeks to kill Garrett. He is fought twice: In the first fight, with the help of Regent of the Mask, Thadeus kidnaps Asia and Irina to lure you and Garrett. You and Garrett must save them without being caught. In the second fight, you and Garrett face him, similar to the fight in 2014 game.

Note: You and Garrett are only playable characters during these boss fights.

Minor Villains/Sub-Boss

While all are Sub-Bosses, five on the second row are fought in Gebel's Castle.

Sweet Tooth (Twisted Metel): The first boss in the game, Sweet Tooth is just there to give troubles on your journey. He'll appear randomly and becomes difficult each time you face him as you process the game. However you face him one last time before you head to Gebel's Castle location.

Legion (Castlevania): Informed by Chelsea, Legion has been terrorizing people from a small village. During the fight, you are aided by Rias and her friends and after you defeat it and leave, Kuroka will see the results.

Elephantaur (God of War: Ascension): Elephantaur will appear randomly as either a minor brute or a difficult sub-boss. There are two version of Elephantaur: One attacks with brute force with his bare hands while another is larger, more difficult, and carries a weapon, mainly a large maces.

Wailing Host (Darksiders II): Like in Darksiders II, Wailing Host attack you be sweeping the floor with his claws. He can also fire projectiles and summon ghouls. By defeating him, you gain the location to Gebel's Castle.

Agreus (Castlevania: Lords of Shadow 2): Sent by Gebel, Agreus fights you before you can access the location of Gebel's Castle. In addition to his attacks like in LOS2, he can create a storm of roses which can do chip damage, though this attack is temporarily.

Demonic Statue: Upon your arrival at Gebel's Castle, you encounter a Demonic Statue. It then begins to move and attacks you. As you attack it, it's appearance change.

Note: The image I used is the Statue of Liberty from the commercial The Strain.

Acnologia (Fairy Tail): A powerful dragon with immense strength and magic powers. He is fought twice: The first fight is, informed by Chelsea, Acnologia attacks a Holy Temple, much to Irina dismay. The second fight is on top of Gebel's Castle.

Note: In the first fight, Irina aids you.

Fenrir (High School DxD): A powerful beast sent by Kuroka in Gebel's Castle. He is fast and attacks with his claws. Be wary on his bite, as it can do massive damage.

Mirror Type Monster: Created by Gebel, this monster attacks you with shards of mirrors. It can also create refelct mirrors to protect itself and imprisoned you. They can be destroyed, but they'll damage you depending on how strong the attack is and type (Physical or Magic). The refelct mirrors will damage you if its the same type but you'll be safe if its different but they're very random, so attack carefully.

Note 1: The image I used is Mirror Force and Krystalak from Yugioh and Godzilla respectfully.
Note 2: The refelct mirrors is inspired by Kurt Zisa attack patterns in KH and the Pokemon moves Reflect and Light Screen.

Rias Gremory (Curse): Gebel and Regent of the Mask placed a curse on Rias after they acquired a piece from Issei's armor after your fight against Fenrir. There are two phases in this fight: The first is Rias herself, once you defeat her (though temporarily), a red crystal will appear behind her, destroy it. After that, Rias will recover and continue her attack (repeat this two more times). The second phase is in her Welsh Dragon Balance Breaker mode. She is faster, stronger, and more difficult in this form.

Note 1: Rias's friends, Miriam, and Ryu are automatically in your party and are only playable characters in the first fight. In the second fight, you and Issei are the only playable character.
Note 2: There are four red crystal you need to destroy in this fight. The final one is within Rias.

Optional Bosses/Secret Bosses

Once you beat the game, you unlock a secret location. There lies an ancient temple awaits, to me, well known heroes and villains. You're first choice is the Villains Section and once you defeat them, you unlock the Heroes Section. This was inspired by Mt. Silver from Pokemon Gold, Silver, the DS remake and Cavern of Remembrance from KH2: Final Mix.

Note: I'll also put their theme that I think would sound cool in their fights.

Villains Section

Absalom (Darksiders II): The first boss in the Villains Section. His attacks are similar in Darksiders II, and is fought in two phases: The first is basic where he attacks you hard by punching, charging, and swinging his axe, Absolution. In the second fight, he'll disappear and let the Corruption attack you by fire projectiles, land mines, and bindings. If you can hold it, Absalom will reappear.
His theme: www.youtube.com/watch?v=G9OTZJ…

Mewtwo (Pokemon): The Second boss in the Villains Section. As a Psychic type Pokemon, Mewtwo will use every known Psychic move (mainly from G1 to X & Y). He'll even used Recover to heal and Reflect and Light Screen to cut your Physical and Magic attacks in half. At the near end of the fight, he'll used his Mega Evolution, depending on the most playable character in the fight that uses Physical or Magic. However if its even, Mewtwo's evolution will be random.

X: If most of playable characters in your party uses Physical attacks, such as Tatsumi and Xenovia, Mewtwo will evolve into Mega Mewtwo X.
Y: If most of the playable characters in your party uses Magic attacks, such as Miriam and Rias, Mewtwo will evolve into Mega Mewtwo Y.

His theme: www.youtube.com/watch?v=ET5cMr…

Megatron (Transformers): The Third boss in the Villains Section. Before you face him, Megatron will send his troops (both regular and brutes) to attack you. You'll have to defeat 1000 of them (similar to KH2). Once you defeat them, Megatron will then appear. In addition to his physical attacks and his Fusion Cannon, he'll also attacks with his Dark Star Saber, which can do massive damage. Somewhere in the fight, Megatron will transform into his jet form and will use aerial attacks and fire from the air.

His theme: www.youtube.com/watch?v=N30YXQ…

Yami Marik (Yugioh): The Forth boss in the Villains Section. He is fought in three phases:

Phase 1: Yami Marik will summon three of his monsters for you to face: Makyura the Destructor, Gil Garth, and Drillago. While you're facing his main monsters, he'll use Nightmare Wheel to bind and damage a random character (it can be destoyred though). Once you defeat his main monsters, Phase 2 starts.

Phase 2: He'll summon Lava Golem and will imprison a random character in his cage. Though the cage can be destroyed, the longer the character is in it, they get damaged. Lava Golem will attack you by sweeping the floor, smash the ground, shoot fireballs, fire flamethrower, and do fire land mines. Once you defeat Lava Golem, the final Phase starts.

Final Phase: He'll summon his most powerful monster, The Winged Dragon of Ra. Ra can do massive damage with his blast attack and can attack all of your party members. Be wary of his Phoenix mode as he can do a one-hit kill.

His theme: www.youtube.com/watch?v=TYbB9E…

Spacegodzilla (Godzilla): The Final boss in the Villains Section. He is fought in two phases:

Phase 1: You first face him in his flying form. You chase him by flying or gliding while avoiding his electrical attacks, crystal projectiles, and meteors (the fight takes place in space). Once you catch up to him and attack his face, the final Phase starts.

Final Phase: Spacegodzilla will throw you on a large rock platform and that's were the fight starts. Like in Phace 1, Spacegodzilla attacks you with electrical attacks, crystal projectiles, and his Corona Beam, which can also attack all party members. He can also create crystals to project himself and imprison you. He'll create two gigantic crystals to enhance his power (though they can be destroyed).

Heroes Section

Death (Darksiders II): The First boss in the Heroes Section. In addition to his main weapons, Harvester and Dual Scythes, Death will aslo used any known sub-weapons in Darksiders II, such as axes and spears. He is fast and is quick to dodge in coming attacks. During the near end of the fight, Death will change into his Reaper Form. In addition to being stronger and faster, he can also summon crows to attack you and ghouls that acts as explosion when destroyed. He'll even use sweep attacks and use large Duel Scythes to attack the area, similar to Death from the Castlevania games.

His theme: www.youtube.com/watch?v=rER8Li…

Red (Pokemon): The Second boss in the Heroes Section. His fight is similar in Brawl and will be like Pokken Tournament where you fight his Pokemon but his team is base on HG&SS. Specifically Pikachu, Lapras, Snorlax, Venusaur, Charizard, and Blastoise. He'll use Mega Charizard X at the near end of the fight. Before you face Red, only six characters of your choosing will participate. However you can choose what form of battle will be before you start: Single Battle, Double Battle, or Triple Battle.

Note: Aeon will not be available in this fight.

His theme: www.youtube.com/watch?v=7xULk_…

Optimus Prime (Transformers): The Third boss in the Heroes Section. His fight starts medium, attacking you by charging, hand-to-hand, and other forms of combat. However later the fight will start to get difficult and he'll know what attacks are coming. In addition to faster and stronger combat, Optimus will start using his main weapons, Ion Cannons, Wrist Blades, and Energon minigun. Using his jetbacks, Optimus will fire from midair and use aerial attacks. Later he'll used the Star Saber which, like the Dark Star Saber, can do massive damage.

His theme: www.youtube.com/watch?v=x4kKXS…

Yami Yugi (Yugioh): The Forth boss in the Heroes Section. Like Yami Marik, Yami Yugi's fight is also in three phases:

Phases 1: Yami Yugi will summon three of his main monsters: Dark Magician, Dark Magician Girl, and Magician of Black Chaos. While you're faceing his main monsters, he'll use Swords of Revealing Light to temporarily stop all of you're party members and Mirror Force to reflect and damage all of your party members. When he up with his last monster, Yami Yugi will use Magical Hats to hide his remaining monster and one of two random traps. Once you defeat his main monsters, Phase 2 starts.

Note: The two random traps in the Magical Hats are Spellbinding Circle which can bind and lower the states of a party memeber or Magic Cylinder which can redirect the attack.

Phases 2: He'll summon an army of Kuribohs using Multiply to protect him and attack you (though the damaged is minor, they'll attack in hordes). Once you defeat them, the final Phase starts.

Final Phase: He'll summon his most powerful monster, Slifer the Sky Dragon. Like Ra, Slifer will attack with his Thunder Force, which can do massive damage and can attack all party members. Be wary of his special attack, when you switch or revive a character, Slifer will automatically attack the character.

His theme: www.youtube.com/watch?v=0BDdmB…

Godzilla: The Final boss in the Heroes Section. Like Spacegodzilla, Godzilla is fought in two Phases:

Phase 1: You start be climbing or flying on Godzilla himself to reach his head. While not as difficult as Spacegodzilla first phase, watch out for incoming objects, crumbled building parts, and his atomic energy from his spikes on his back. Once you reach his head, the next Phase starts.

Final Phase: Godzilla will notice you and throws you to a large building platform. That's were the fight begins and if you're not careful, Godzilla will defeat you with few attacks. He will attack you hard by biting, clawing, and tail whip. Later he'll use his most defastating attack, Atomic Breath, which can do massive damage and can attack all party members. If get to close to him, Godzilla will also use his Nuclear Pulse.

Martis (Yugioh Forbidden Memories): A member of Gebel's group and the first of the group you face. Before you face him, he will summon two large golems to protect him.

Thadeus Harlan (Thief): A hunter for hire. He was hired by Gebel and seeks to kill Garrett. He is fought twice: In the first fight, with the help of Regent of the Mask, Thadeus kidnaps Asia and Irina to lure you and Garrett. You and Garrett must save them without being caught. In the second fight, you and Garrett face him, similar to the fight in 2014 game.

Note: You and Garrett are only playable characters during these boss fights.

Minor Villains/Sub-Boss

While all are Sub-Bosses, five on the second row are fought in Gebel's Castle.

Sweet Tooth (Twisted Metel): The first boss in the game, Sweet Tooth is just there to give troubles on your journey. He'll appear randomly and becomes difficult each time you face him as you process the game. However you face him one last time before you head to Gebel's Castle location.

Legion (Castlevania): Informed by Chelsea, Legion has been terrorizing people from a small village. During the fight, you are aided by Rias and her friends and after you defeat it and leave, Kuroka will see the results.

Elephantaur (God of War: Ascension): Elephantaur will appear randomly as either a minor brute or a difficult sub-boss. There are two version of Elephantaur: One attacks with brute force with his bare hands while another is larger, more difficult, and carries a weapon, mainly a large maces.

Wailing Host (Darksiders II): Like in Darksiders II, Wailing Host attack you be sweeping the floor with his claws. He can also fire projectiles and summon ghouls. By defeating him, you gain the location to Gebel's Castle.

Agreus (Castlevania: Lords of Shadow 2): Sent by Gebel, Agreus fights you before you can access the location of Gebel's Castle. In addition to his attacks like in LOS2, he can create a storm of roses which can do chip damage, though this attack is temporarily.

Demonic Statue: Upon your arrival at Gebel's Castle, you encounter a Demonic Statue. It then begins to move and attacks you. As you attack it, it's appearance change.

Note: The image I used is the Statue of Liberty from the commercial The Strain.

Acnologia (Fairy Tail): A powerful dragon with immense strength and magic powers. He is fought twice: The first fight is, informed by Chelsea, Acnologia attacks a Holy Temple, much to Irina dismay. The second fight is on top of Gebel's Castle.

Note: In the first fight, Irina aids you.

Fenrir (High School DxD): A powerful beast sent by Kuroka in Gebel's Castle. He is fast and attacks with his claws. Be wary on his bite, as it can do massive damage.

Mirror Type Monster: Created by Gebel, this monster attacks you with shards of mirrors. It can also create refelct mirrors to protect itself and imprisoned you. They can be destroyed, but they'll damage you depending on how strong the attack is and type (Physical or Magic). The refelct mirrors will damage you if its the same type but you'll be safe if its different but they're very random, so attack carefully.

Note 1: The image I used is Mirror Force and Krystalak from Yugioh and Godzilla respectfully.
Note 2: The refelct mirrors is inspired by Kurt Zisa attack patterns in KH and the Pokemon moves Reflect and Light Screen.

Rias Gremory (Curse): Gebel and Regent of the Mask placed a curse on Rias after they acquired a piece from Issei's armor after your fight against Fenrir. There are two phases in this fight: The first is Rias herself, once you defeat her (though temporarily), a red crystal will appear behind her, destroy it. After that, Rias will recover and continue her attack (repeat this two more times). The second phase is in her Welsh Dragon Balance Breaker mode. She is faster, stronger, and more difficult in this form.

Note 1: Rias's friends, Miriam, and Ryu are automatically in your party and are only playable characters in the first fight. In the second fight, you and Issei are the only playable character.
Note 2: There are four red crystal you need to destroy in this fight. The final one is within Rias.

Optional Bosses/Secret Bosses

Once you beat the game, you unlock a secret location. There lies an ancient temple awaits, to me, well known heroes and villains. You're first choice is the Villains Section and once you defeat them, you unlock the Heroes Section. This was inspired by Mt. Silver from Pokemon Gold, Silver, the DS remake and Cavern of Remembrance from KH2: Final Mix.

Note: I'll also put their theme that I think would sound cool in their fights.

Villains Section

Absalom (Darksiders II): The first boss in the Villains Section. His attacks are similar in Darksiders II, and is fought in two phases: The first is basic where he attacks you hard by punching, charging, and swinging his axe, Absolution. In the second fight, he'll disappear and let the Corruption attack you by fire projectiles, land mines, and bindings. If you can hold it, Absalom will reappear.

Mewtwo (Pokemon): The Second boss in the Villains Section. As a Psychic type Pokemon, Mewtwo will use every known Psychic move (mainly from G1 to X & Y). He'll even used Recover to heal and Reflect and Light Screen to cut your Physical and Magic attacks in half. At the near end of the fight, he'll used his Mega Evolution, depending on the most playable character in the fight that uses Physical or Magic. However if its even, Mewtwo's evolution will be random.

X: If most of playable characters in your party uses Physical attacks, such as Tatsumi and Xenovia, Mewtwo will evolve into Mega Mewtwo X.
Y: If most of the playable characters in your party uses Magic attacks, such as Miriam and Rias, Mewtwo will evolve into Mega Mewtwo Y.

Megatron (Transformers): The Third boss in the Villains Section. Before you face him, Megatron will send his troops (both regular and brutes) to attack you. You'll have to defeat 1000 of them (similar to KH2). Once you defeat them, Megatron will then appear. In addition to his physical attacks and his Fusion Cannon, he'll also attacks with his Dark Star Saber, which can do massive damage. Somewhere in the fight, Megatron will transform into his jet form and will use aerial attacks and fire from the air.

Yami Marik (Yugioh): The Forth boss in the Villains Section. He is fought in three phases:

Phase 1: Yami Marik will summon three of his monsters for you to face: Makyura the Destructor, Gil Garth, and Drillago. While you're facing his main monsters, he'll use Nightmare Wheel to bind and damage a random character (it can be destoyred though). Once you defeat his main monsters, Phase 2 starts.

Phase 2: He'll summon Lava Golem and will imprison a random character in his cage. Though the cage can be destroyed, the longer the character is in it, they get damaged. Lava Golem will attack you by sweeping the floor, smash the ground, shoot fireballs, fire flamethrower, and do fire land mines. Once you defeat Lava Golem, the final Phase starts.

Final Phase: He'll summon his most powerful monster, The Winged Dragon of Ra. Ra can do massive damage with his blast attack and can attack all of your party members. Be wary of his Phoenix mode as he can do a one-hit kill.

Spacegodzilla (Godzilla): The Final boss in the Villains Section. He is fought in two phases:

Phase 1: You first face him in his flying form. You chase him by flying or gliding while avoiding his electrical attacks, crystal projectiles, and meteors (the fight takes place in space). Once you catch up to him and attack his face, the final Phase starts.

Final Phase: Spacegodzilla will throw you on a large rock platform and that's were the fight starts. Like in Phace 1, Spacegodzilla attacks you with electrical attacks, crystal projectiles, and his Corona Beam, which can also attack all party members. He can also create crystals to project himself and imprison you. He'll create two gigantic crystals to enhance his power (though they can be destroyed).

Heroes Section

Death (Darksiders II): The First boss in the Heroes Section. In addition to his main weapons, Harvester and Dual Scythes, Death will aslo used any known sub-weapons in Darksiders II, such as axes and spears. He is fast and is quick to dodge in coming attacks. During the near end of the fight, Death will change into his Reaper Form. In addition to being stronger and faster, he can also summon crows to attack you and ghouls that acts as explosion when destroyed. He'll even use sweep attacks and use large Duel Scythes to attack the area, similar to Death from the Castlevania games.

Red (Pokemon): The Second boss in the Heroes Section. His fight is similar in Brawl and will be like Pokken Tournament where you fight his Pokemon but his team is base on HG&SS. Specifically Pikachu, Lapras, Snorlax, Venusaur, Charizard, and Blastoise. He'll use Mega Charizard X at the near end of the fight. Before you face Red, only six characters of your choosing will participate. However you can choose what form of battle will be before you start: Single Battle, Double Battle, or Triple Battle.

Note: Aeon will not be available in this fight.

Optimus Prime (Transformers): The Third boss in the Heroes Section. His fight starts medium, attacking you by charging, hand-to-hand, and other forms of combat. However later the fight will start to get difficult and he'll know what attacks are coming. In addition to faster and stronger combat, Optimus will start using his main weapons, Ion Cannons, Wrist Blades, and Energon minigun. Using his jetbacks, Optimus will fire from midair and use aerial attacks. Later he'll used the Star Saber which, like the Dark Star Saber, can do massive damage.

Yami Yugi (Yugioh): The Forth boss in the Heroes Section. Like Yami Marik, Yami Yugi's fight is also in three phases:

Phases 1: Yami Yugi will summon three of his main monsters: Dark Magician, Dark Magician Girl, and Magician of Black Chaos. While you're faceing his main monsters, he'll use Swords of Revealing Light to temporarily stop all of you're party members and Mirror Force to reflect and damage all of your party members. When he up with his last monster, Yami Yugi will use Magical Hats to hide his remaining monster and one of two random traps. Once you defeat his main monsters, Phase 2 starts.

Note: The two random traps in the Magical Hats are Spellbinding Circle which can bind and lower the states of a party memeber or Magic Cylinder which can redirect the attack.

Phases 2: He'll summon an army of Kuribohs using Multiply to protect him and attack you (though the damaged is minor, they'll attack in hordes). Once you defeat them, the final Phase starts.

Final Phase: He'll summon his most powerful monster, Slifer the Sky Dragon. Like Ra, Slifer will attack with his Thunder Force, which can do massive damage and can attack all party members. Be wary of his special attack, when you switch or revive a character, Slifer will automatically attack the character.

Godzilla: The Final boss in the Heroes Section. Like Spacegodzilla, Godzilla is fought in two Phases:

Phase 1: You start be climbing or flying on Godzilla himself to reach his head. While not as difficult as Spacegodzilla first phase, watch out for incoming objects, crumbled building parts, and his atomic energy from his spikes on his back. Once you reach his head, the next Phase starts.

Final Phase: Godzilla will notice you and throws you to a large building platform. That's were the fight begins and if you're not careful, Godzilla will defeat you with few attacks. He will attack you hard by biting, clawing, and tail whip. Later he'll use his most defastating attack, Atomic Breath, which can do massive damage and can attack all party members. If get to close to him, Godzilla will also use his Nuclear Pulse.
