Could you trust them? No. Could you enjoy playing with them, as a kid? Definately! These were so cool, they deserve their own category. Lots of soft goods, weird and odd weapons. Bizarre names and just overall strangeness made them favorites for many a kid. Who in Jabba's cohort would be the major domo for you?

Bib Fortuna
Klaatu
Klaatu Skiff Guard
Nikto
Barada
Gamorrean Guard
Ree-Yees
Weequay
Squid Head
Amanaman
Yak Face
Rancor Keeper (yeah, he's not truly an alien, but he fits nowhere else)

Wow! That's quite a motely crew, especially considering most of them died in the movie (unless you believe the EU books).
