Quickdeath was a male NightWing assassin who had been hired by Queen Vigilance to murder Darkstalker in Darkstalker (Legends). He was known by Thoughtful for his reputation, making it possible that he was a famous assassin to the tribe.
When Darstalker, Clearsight, Fathom, Listener, Whiteout, and Thoughtful attend the annual NightWing Jubilee Festival, Quickdeath sneaks up on them and tries to assassinate Darkstalker by plunging a spear in his heart. This failed, of course, because of Darstalkers invincible scales. Quickdeath was then killed by Lionfish, trying to protect Fathom from harm.
- Quickdeath's name is ironic because he got killed soon after the attempt even though he was an assassin hired by Queen Vigliance.
- He is one of the four characters whose name is ironic, the others being: Coconut, Quickstrike, and Chameleon.
- Quickdeath is the third known NightWing assassin (The others being Deathbringer and Quickstrike)
