I read recently that Cyclops' optic blasts don't produce heat. I found this very surprising. I watched X-Men: The Animated Series growing up, and re-watched it not that long ago as an adult. I definitely came away with the impression that he was shooting eye-lasers, which burnt and melted things.
Then, in X-Men: Apocalypse, Scott blasts apart a tree when asked to fire at an archery target. Xavier's favorite tree. I recall the tree burning, or at least glowing. But I can find neither a picture of the tree nor a clip of the scene to confirm my memory.
I believe there are other examples of this sort of thing occurring in other comics, shows, and movies. I'd appreciate additional examples, if anyone is aware of any. I'll add any more I come across.
So what's the deal? Do the blasts produce heat or not? If not, why was the tree burning?
