Jason Todd was the second Moonwing after Dick Grayson. Dick resumed the mantle after Jason's death.
He was apparently killed by the Jackal when a bomb meant for Bruce Wayne and Dark Claw brought a building down on top of him.
He resurfaced as Deathlok working for Madame Cat of Hydra. He holds a grudge against Bruce and Dick for leaving him to die. He battled Dick and nearly killed him but was gunned down by Nick Fury in a SHIELD jet. It is not stated if he survived.
Deathlok wears what Madame Cat describes as a 'cyborg suit.' It is unknown if he has any cybernetic implants.
