Quickdeath was a male NightWing assassin who had been hired by Vigilance to murder Darkstalker in Darkstalker (Legends). However, Quickdeath was killed shortly after the attempted assassination. He was known by Thoughtful for his reputation, making it possible that he was a famous assassin in the tribe.
Quickdeath has iron-tipped claws.
When Darkstalker, Clearsight, Fathom, Listener, Whiteout, and Thoughtful attended the annual NightWing Jubilee Festival, Quickdeath sneaks up on them and tries to assassinate Darkstalker by plunging a spear into his heart. This failed, of course, because of Darkstalker's invincible scales. Quickdeath was then immediately killed by Lionfish, who was trying to protect Fathom from harm.
- Quickdeath's name is ironic because he was killed soon after his assassination attempt, even though he was a trained assassin.
- Quickdeath is the third known NightWing assassin, the others being Deathbringer and Quickstrike.
