10 Video Game Transformations Nobody Saw Coming

10. Titan Joker - Batman: Arkham Asylum

Given that The Joker isn't exactly the most physically imposing foe in Batman's rogues gallery, Arkham Asylum developers Rocksteady had to get creative when designing the game's final boss battle against the Clown Prince of Crime.

They made the totally unexpected and highly divisive decision to have The Joker chug an overdose of the Titan mutagen in a last ditch attempt to kill the Caped Crusader.

As such, the Joker we know and love is transformed into a gigantic, hulking, shirtless brute with ripped trousers who looks more like the Hulk than his namesake.

As surprising as it was, most fans understandably felt that having The Joker turn into a steroidal action figure caricature of himself complete with a ridiculous mohawk haircut ran counter to the game's generally more subdued and restrained atmosphere.

It doesn't help that the subsequent boss fight is the least interesting and creative in the entire game, suggesting Rocksteady ran out of generally good ideas for how to stage a satisfying climactic battle between the iconic hero and villain.

Though Joker's decision to dose himself with Titan had major implications for his role in the sequel Arkham City, the initial transformation was just a step too silly for many.
