Hero is actually a lot more retarded as well as unstable (sexually and mentally) then Bloo though. There's much more of a method to Bloo's madness then Hero, who actually did show some superpowers in this one. He flew and then speeded around at some points. More then I can say for Ling Ling. (I know it won't happen, but they needed an episode of this show where Ling Ling "evolved" and fought Captain hero if only to throw out a bunch of anime fighting parodies and superhero fighting parodies that we didn't really get much of in the show).
Normally I'm down on the hero plot but it was defintley the stronger one this time around thinking about it. At the very least it's more believable Hero would be so retarded he'd think he'd need a nipple ring to be special and then when finding he could talk to the past use it to humilate his past self by making him stick his d*** in a sandwitch several times (funniest was when he did it instead of saving the barn from burning down). Even the ending twist with little hero getting back at bigger hero was good (though the way Captain Hero's weehole was taken out by the garbage disposal... yeah too much inofrmation). So that plus Xandir remarking at Hero's continued stupidity, sandwitch eating hand, Lois Lane parody, and hero's just general unsteadyniess (plus the whole bit with the computer that was the most LOL moment of the ep) was actually pretty good. Actually the Ling Ling plot was disappointing this time around. I don't really care enough about Foxxy's family to really care we finally saw her dad and her reconnect with him, and the whole reuse of the waiting for cigarettes joke that was funnier in season three's premiere ep. That plus I was hoping Ling Ling would do more then just take abuse (though that's what he seems to do for most of the eps anyway) for that first half. So yeah defintley one of the weaker plots which balances out to be a fairly decent ep. I'll give it a bit of a raise for an unexpected Garfield spoof. Otherwise could of actually used more Hero and his Frequnecy parody this time around.
