Spider-Man and Venom:
On the left is a true snapshot of the game's first cinematic sequence.
In the two middle pictures, I adjusted the colors for Mario Paint, and shrank the image's size down to 90%, so that it could fit.
On the right, you'll see that, at 90% size, the image can (just barely) fit in Mario Paint.
It's just a shame Mario Paint had no "dark red" color. It could come in very handy with Carnage.
