Kinda random but I've been watching the new series lately and i used to watch the old ones ages ago. I love the aliens designs they're so distinctive and have awesome powers. So I was wondering if theres other fans here, who are your top fav aliens?

I only liked old Ben 10... Hate what I've seen from the new series since I got so attached to the first 20 or so aliens.

Diamondhead will forever be my favorite, I suppose.

bastard show took away teen titans! .. but it was pretty good.

Swampfire's my favorite.

Benvictor, Armodrillo, Humongousaur, Brainstorm, Ultimate Echo Echo, Ultimate Humongousaur, Clockwork, Big Chill

The new one got repetitive after Alien Force, but the old one was great. XLR8 is my favorite alien, and Benwolf comes in a close second.

I never liked Ben 10, especially because in the original series Ben was such a douche.

I always liked Four Arms. I've... well, always wanted four arms. I also really like XLR8 and Big Chill.

I used to love watching the original series with my little brother, but I don't like the new ones. I love all the aliens. But I guess that Fourarms, Diamondhead, XLR8 and the fire one (why the heck can't I remember it's name?!) were my favorites.

Benwolf ftw.

XLR8 was also pretty epic, as was that fire one I can't remember the name of. There were probably a couple others but I've not seen that show in forever.

XLR8, Swampfire, Enourmosaur and Alien X.

I lost interest after the 1st series. I liked Firearms?

I watched Ben 10 and Ben Alien Force, but now they just suck. Only watch Ultimate Alien.
