Quickdeath was a male NightWing assassin who had been hired by Queen 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.
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 got killed soon after the attempt even though he was an assassin hired by Queen Vigilance.
- He is one of the seven characters with ironic names, the others being Coconut, Quickstrike, Slaughter, Scarlet, Secretkeeper and Chameleon.
- Quickdeath is the third known NightWing assassin (The others being Deathbringer and Quickstrike).
- It is possible Quickdeath’s name is a combination of Quickstrike and Deathbringer.
