Okay, here's what I've decided about Firestorm's powers · 12:50pm Jul 29th, 2017
Joker here. Well, after giving the matter a bit of thought last night, I've decided that my version of Firestorm will have most of the powers of the comic book version, except the power of Molecular Reconstruction, because that, in my opinion, would make him considerably OP. I mean, according to my research, in Firestorm's big debut in the comics, he turned a guy's gun into a cucumber and turned the floor of the place they were fightning in into a big hole. Sounds a little OP in my book. And, of course, he'll still have that quantum splicer that keeps him from going nuclear and turning Canterlot City into a big crater. Of course, I know a couple of Eggheads (both versions of Twilight and Sunset Shimmer) who would be more than eager to run tests on Firestorm in the name of...
That's all for now. Stay perky.
Not to nitpick, but if his main powers inherently involve molecular manipulation then the whole 'turn the floor into a hole' is simply a matter (pun not intended) of making the substance less dense by opening the gaps between molecules or atoms without changing the actual substance at all.
