This is so hard! How am I supposed to choose out of the several dozen on-screen aliens? I like all of them! Well, I think some aliens should be stronger and have a higher potential (like Way Big, Atomix, Four Arms, Humungousaur, Diamondhead etc.) and some (like Goop, Bloxx, Stinkfly, Fasttrack, Kickin' Hawk etc.) are unnecessary, but still. How am I supposed to choose?

Upgrade is mine
