Comedian was probably the strongest of the Watchmen aside from Ozy, even in his old age. Also he was arguably the most skilled(again aside from Ozy) as he continued fighting up until the point he was killed, and was ruthless and a dirty fighter. Any of the Watchmen would easily destroy Bane, and you picked one of the toughest ones, lol.
the comedian for the win, he tanked massive hits and seemingly brutal damage even though he was past his prime. Bane may have skills from the league of assassins but against the comedian who is able to withstand so much and keep thrashing out... Bane loses
From the movie, I dont remember Comedian fighting Ozy at all, other than what Ozy actually killed him, and Comedian hardly did well there at all. Bane was durable enough to take all of Batmans strikes and strong enough to destroy him in return. I dont see Comedian being able to take down Bane, and Im totally fine if Im the only one who thinks this.
