Re: Worst comic book superfight ever
You're right about the icon, at least.
Remember earlier when I said that this argument might make sense if you could find a panel of a bunch of shadowy Thors or a Thor-colored whirlwind surrounding Firelord? I'm saying it again now.
Some artistic conventions are designed to show a character doing something really fast, or really often. The "bunch of shadowy versions of a character doing things in one panel" is one such convention that got its start, I believe, in old Johnny Quick comics. It's a time-honored art trick.
A bunch of shadowy Spideys attacking Firelord in one panel, therefore, is a symbolic representation of Spidey attacking Firelord a lot. It's an artistic shorthand. Your comparison here is a false one and has no merit unless you can show similar artistic conventions being used in a Thor vs. Firelord fight.
Tell your friend that, too.
