In Weapon X (2nd series) #10, his mind was virtually wiped clean by Cable's telepathic power. He was apparently still alive enough to be depowered, as confirmed in New Avengers (1st series) #18. His powers were restored in X-Factor (3rd series) #20 by Quicksilver, but he fled into the Brimstone Dimension when his abilities began to destabilize. His current fate is unknown.
The Tradesman enhanced Reaper's scythe so that is could be used to displace individuals through dimensions. His time in the Ultraverse extended from All New Exiles Infinity until Ultraverse Unlimited #2.
Reaper's true name was revealed in X-Force (1st series) #26.
