The Green Lantern has a bit of that stupid-sexy-flanders-butt going on here, but that's inevitable when you're in good shape and wear underwear about in public.

Sonar was a Middle-European supervillain - hence the peculiar costume and tell-tale hank of skull-plastered hair.  Even from a distance, he looks like a 19th century Hungarian bureaucrat, albeit one who stole his costume from the Smallville Marching Band.

When you think about it, conquering sound doesn’t seem to be that great an accomplishment, since you can’t imagine sound putting up much of a fight. This may be why the editor looked at the original illustration, unscrewed the cigar from the corner of his mouth, and said “move the action upstairs.”

“Uh – but how can Sonar fly? He conquered sound, not gravity.”

“He has a supersonic punch, doesn’t he? Well, planes are supersonic. Planes fly.”

The cape looks as useless as capes usually do. It may have been their way of hiding visible underwear lines. You had a good butt, you left off the cape. Hell, you probably left off the supporter, too. If you were going to take a supersonic punch in the yarbles, a layer of elastic fabric wouldn't make much difference. Besides, when you fought? In the air? Chafe city.
