The best superhero in a skirt...

...is Magnus, Robot Fighter, without a doubt.  Oh, you were thinking Miss Martian, maybe?  Or Supergirl?  Nope.  It's this guy.  Yep, that's right, I said "guy."

Eat your heart out, Hal Jordan.

Well, I didn't say "guy," I typed it.  But enough of that.

Don't let the skirt fool you.  If you're an evil robot overlord, you better watch yourself, or you'll get torn in two.

It's called a tunic, dammit!!!  How many times do I have to tell you people that?!  I will take out my agression on this helpless Pol-Rob.  RAWRRGGH!!!

Or cleaved down the middle like warm butter...

Or you'll get your robot head karate-chopped off.

Bringing sexy back, one lethal backhand at a time.

So, lesson learned: never get on the wrong side of a man who wears a skirt.
