I try not to be judgmental, but I'm going to go out on a limb here and say that "crapping fire" is not a bona-fide super power:

At least the flaming feces are in handy pellet form, useful (presumably) for flinging at enemies. Although given the way Spidey is cringing in horror, I doubt that's going to be happening any time soon.
Oh, is that what that is? I thought he had a flaming something else between his legs.
Here is a fun contest. See how Spidey’s and flaming dude’s word balloons are cut off but you get a few words? Maybe it would be funny to make up the rest using the few visible words. Like the old match game!
Yeah, showin my age.
Who is taht anyways?
Looks like an early version of Adam Warlock?
I don’t know, Rick, it’s one panel from a digest-style synopsis of the Spider-Man story up to that point in time, so you only get one or two panels from significant issues as a very high-level recap. He’s standing in front of Doom or Super Skrull or some other Avengers villain, and he’s saying something about being “The Ultimate Avenger”. It could be Warlock, I suppose, but I didn’t get that impression, it seemed more like the other Avengers had been combined or something.
But it was just one panel, so I am not sure. I couldn’t find anything about it online, although to be honest I didn’t really look that hard.
