>>93624624>some aliens double up on abilities Sure, that's all fine and good, but in any given array of aliens, it's highly likely that you'll have aliens who fit the bill and have other attributes that make them a better choice.
As for the Omnitrix turning them into captain America, I don't know that that's the case. According to WOG, it would turn them into Ben due to his bond with the Omnitrix. Even if it did manage to turn them into Captain BenMurrica, the peak of human physical perfection is still pretty lacking when you compare it to other forms.
As for Rook keeping up with Ben, I haven't seen too much of omniverse, but from what little I've seen, Rook seems to outpace ben, not the other way around. Even other 'boring' races appear to be more fit than we are.
I won't deny that bens done a lot of stuff without the watch, but he's also Ben, and comes from a family that produces baddasses like they're going out of style.
My question is still the same - what could an alien do with us humans that they wouldn't be able to do with any other species.
