Ah, the obligatory super hero punch-up scene!
There are few things we can rely on in this world but the fact that a super hero story (whether serious or parody) will end in a one-on-one bout of fisticuffs between hero and villain must be right up there along with the fact that it will rain if you go out without an umbrella.
The only exception to the punch-up ending is an explosion. Usually an explosion involving the villain's secret lair or Earth-threatening doom-machine. Obviously when I wrote this, the shop must have been all out of death-stars and so you get the fist fight instead.
And more copied shading.
