Titan Joker

Titan Joker is The Joker after he has used the super-steroid, Titan. He is the final boss in the acclaimed video game, Batman: Arkham Asylum. The Joker had hired Doctor Penelope Young to create an enhanced version of Bane's Venom. It turns any average person into a Bane-like being, but they loose all sanity as compensation. The Joker's scheme was to use the Titan Formula to create a super army to take over Gotham City, but after Batman intervenes, The Joker turns to his last option, using the formula on himself.

Physical Traits
The Titan-Powered Joker is around the same size as Killer Croc (a height of 11 feet). Because the Titan Formula is so fast acting, much of The Joker's skin has torn away to reveal enlarged muscles and sharpened bones. As well, his fingernails are over-sized and sharpened, and his hair forms a mohawk-shape.

The Final Showdown
During the last fight he and Batman have in Batman: Arkham Asylum, The Joker continuously swats at Batman, after some swatting, he retreats to let his minions and bombs do the work. After some time, Jack Ryder's helicopter flies overhead to capture the fight for the news, this distracts Joker, giving Batman time to do serious damage. Eventually - after he is defeated - the Titan Formula wears off, leaving The Joker horribly disfigured and ill.
