Doing the trend

Phantom dies at 89 after being stabbed with his own weapon.

K’horr manages to wipe out all of humanity when Phantom dies, and the Xarranian race lives on Earth for another 5,000 years. He dies peacefully at 572.

Denny, Light, and Dark die during the universe’s light death (yes, Denny is immortal)

also the mechanic’s already dead lol

they are both immortal.
