Classic Battle Royale

Bane (Origins) (Arkhamverse) I never played, but I saw some gameplay and would go with Bane.

Bane (Origins) (Arkhamverse) @Juggenaut bane was arguably batmans strongest foe, he figured out batmans identity pretty early on and nearly killed alfred, he pretty much won against batman in his first fight and kinda won in the second fight where batman had to "cheat" and put bane into cardiac arrest and later reviving him.
