Kryptonian.

 Hmmm that's a really hard question, from Mass Effect I would probably be a Turian, can't really remember alot of other alien races from other stuff at the moment

Definitely a Skrull. 
 
The shit I'd make Jeff do....

Wookiee, that way I'd get a sweet bowcaster.

Hm. Either a Protoss templar or one of those tentacle monsters in Japan.

Ewok

I'd probably like to be a Protoss Dark Templar, being exiled doesn't sound bad if I can walk around invisible and you can live a hell of a long time being Protoss.
Either that, or stick to being human. Life ain't bad on Earth if you ask me ^^

Tentacle monster...

Whatever Yoda is.

"

I'd be an Andalite.  It's a creature from K. A. Applegate's Animorphs.  It can chop a tree down with one swing of its tail blade. "

" @TheSeductiveMoose:
Yeah, what race is Yoda? "

"

Hmm Alien or predator I just cant decide...

Dang...I'd say Asari, but they're female-only. The next one would be Krogan, but they're...Krogan.

Do Turians live for a thousand or so years? I know Krogan and Asari can, but not if Turians can. If they can, I'd be one. If not, they I'd say Krogan. Well, only Krogan if I could leave that shit hole that is Tuchanka. It'd be interesting living for a thousand years (y'know, if someone doesn't murder my ass).

If not, then screw it, Human. Salarian's, even with their short life spans, would be interesting as well.

I would like to have a Quarian friend, but I wouldn't want to be one.
 
Edit: Forerunners would be awesome if not for that whole "being extinct" thing. Sangheili/Elites would be interesting too.

Probably a Drell. I mean, you get the slender body of a human, swimming abilities, and a perfect memory, although Turians and Krogans are pretty awesome, too.

Turian. 
 
Nope. I lied.  I'd rather be a sea-biscuit!

"Tentacle monster...

"

I can't believe I was the first to say this, but:  

Eff Yoda, I'd rather be a Mon Calamari.

" 

From Star Trek to Mass Effect, WoW to Tolkein, what alien race would you be from in another life time and why?I would definitely be a vulcan - I  wouldn't  have to endure all of the rage that flows through me every time I encounter an illogical person who lacks the ability to comprehend my cool, calm rationale (and common sense in general). "

A normal alien.

" Tentacle monster...

"

Transformers are aliens, right? I'd be one of those. Or maybe Klaatu from The Day The Earth Stood Still but not the one from the kinda-junky remake from a couple years back, the bad-ass nice guy from the original movie.

Asari

Remember the hopeless Alien race from Galaxy Quest that thought Television was Historical Documents? Yeah? Well I used to want to be that Until the Turians came along.
 
I'd want to be a Turian Space cop.

From a quick search Pleiadian. Or protoss or asari.

Seriously? No one? No one yet!! WTF is the matter with you people.
 

*snaps fingers* 
 
Cool, now the Dragonball universe never existed. Yay!
 
Q > all.
