The comic book I get for Fantastic Four depicts them as kids with accidentally gained superpowers. Theyre somewhere in their late teens or early twenties, and nice and powerful. With such powers, I'd imagine the fights are pretty monumental. Here is the studious Invisible Woman exacting her revenge on the Human Torch for interrupting her. I think Susan will end up winning, because she really could beat fire quite easily. I doubt she'll be able to save that book though. I did this with Photoshop off of a pencil sketch which is there for all to mock on my gallery. I think there will be a revision since I HATE how Johnny's shirt came out and I need to make a real background.
