Why is Green Arrow's sidekick named Speedy? Shouldn't Speedy, by any logic whatsoever, be the Flash's sidekick? Don't get me wrong, I much prefer Kid Flash, but "Speedy" has very little to do with arrows. Has the name ever been explained?
Same with Toro. How did the original Human Torch end up with a sidekick named Toro? Toro should have been a Contest of Champions Hispanic bull-themed hero, not a kid who spontaneously combusts. "Toro" has absolutely nothing to do, as far as I can think of, with being on fire.
Bucky doesn't appear to have buck teeth, nor does he typically ride horseback. Why did Crimson Avenger have Wing? Shouldn't Wing have been Hawkman's sidekick? How lame must it have been to charge into battle saying "You'll never stop TNT and his trusty sidekick, Dan!"?
Robin has been explained (and makes at least some greater sense in light of Kane's initial idea for a "Bird-Man" character). Batgirl, Supergirl, Bulletgirl, Wonder Girl, Kid Flash, Aqualad, etc. all make immediate sense. What the heck is up with the rest of the sidekick brigade?
