Tyler1's autism breakout

You are correct, but he can be defeated by the strongest of magic. but never killed.

Spike absorbs and corrupts energy to grow stronger, so you can do whatever the hell you want and heĺl just get stronger

So every type of energy..
hmm..
By this Spike is basically an Energy being. He cannot die, and is immortal. However, like most energy beings, only have 1 way to die. that way is practically unknown to mankind. Spike himself should know this, and shouldn't be worried about this since no-one knows how an energy being can actually die.

correct

i'd rather race him in a car anyways
