Jason Todd hasn't been shown in the games, but the Joker drops clues that he existed and was killed.

For this custom, I decided to take the comic design and push it to an extreme like the other game models. The design principle was that he recycled parts of his old Robin costume(same one Tim is wearing) to create the new gear. It has an armored jacket, and Robin's boots and bracers. The chest has a spray-painted 'bleeding' bat logo, etc. Most of the parts are pretty basic fodder...

Head, feet, belt, bracers: DC Direct AC Robin
Jacket: Mattel Avatar guy
Legs: Mattel Captain Cold
Hands: Mattel Jonah Hex
Guns and belts: DC Direct Comedian
Torso: mattel Batman Begins Vigilante Bruce Wayne

Enjoy!
