The Bison/IvanRider

Recruitment cost justification
Since the Bison is almost game-breakingly powerful, it would cost 4000 command points to purchase him. This would be $500 in USD, making him the equivalent of an old version of Photoshop in price.

For those who don't have that kind of money, the Bisonic Lockbox collection would provide an alternate route to acquiring him. Only four covers would be required: The Bison, The Bison Reborn, The Bison Dilemma, and The Bison Aquafied: Rise of the Eel Thing.

A Spec Op battling Bisonte Black and the Eel Thing would introduce these lockboxes, and the Bison would be a group boss. Since he's pretty much indestructible, 0% would merely result in him fleeing to Antarctica to recuperate.

Trivia

 * He doesn't raise his hooves to fly.
 * A song about him was written here.

Recruitment quote

Additional special requirements
No two Bison are allowed in PvP. But if a player goes up against another who has the Bison, they will be rewarded 5X normal XP for forfeiting the match.

Moveset

 * L1: Sluuurrrrp: Inhales an opponent, then causes them to go through a portal in his stomach to some point in the sky, where they have to fall back to the ground. The higher level he is, the higher enemies are dropped from and more damage this move can inflict.
 * L2: Hoof and Gore: Attacks enemies with red-hot hooves that brand their flesh, causing Burning moodlet, then impales them with horns to cause Internal Bleeding.
 * L6: Possession: Will apply Mind Control and Meltdown moodlets to an opponent, causing them to protect the Bison's team and explode violently if under 25% health.
 * L9: Burn Your Soul: Similar to Ghost Rider's Penance Stare, but does a lot more damage.

Character-Restricted Empowered ISO-8

 * Slurpent ISO-8: Upgrades "Sluuurrrp" to the Slurp Cycle, inflicting more damage and affecting all enemies instead of just one.

Team-up Bonuses

 * American Made: If he teams up with Captain America.
 * Doom: If he teams up with Dr. Doom.
 * Red in the Ledger: If he teams up with Dr. Doom.
