Asteroid

Asteroid lives in a pretty modern world despite his looks- He's lived through the changing times for centuries and finds it nice to be somewhat 'alive' during a high technology age.
Though he accepts the changes (very stubbornly) and understands most things, he still needs help from time to time like any old dino.
No one quite knows how he's still here but he'll be here for quite a while more...
=====================================
-Has a short temper and can be stubborn at times
-The comet is usually cool but raises in temperature when angered, even setting on fire
-He's very angry about it since he originally died from the dumb rock
-He just wants to relax and chill out, pls give him a break
