Space invaders

I though something like a "Destroy all humans" or something around retrofuristic and or humoristic aliens combined with serious ones.

428) Interdimentional invader: You know, much like the page of interdimentional beings? well this one comes to cause trouble on earth sucking people into his own dimension.

429) Brainchains: They are pretty stupid for being someone as intelligent as them. I being quick with the descriptions, I know. I don't know, they could use some cheap telekinetic and telephatic powers.

430) Geonosian: Yes, I know I reaped that name from Episode II, but I made it while I was sleeping, so its legal >_> ... right?
You see, I dreamed with this thing, actually it was in the cover of the box of a completely different game I dreamed, some they I might tell you the details, but it came with all and name included, so I respected that. No clue what it is supposed to do.

431) Invader: A cliche space invader with the fishbowl helm and stuff. It would shoot at people with a cliche ray-gun n' stuff.

432) Examorph: Some kind of organic monster with... organic weapons, you know spines, tentacles, spores, regular stuff.

433) Colossi: Slightly based on Apocalypse from the X-men and other powerful robot-looking beings from comics and video games. They would not be intended to look graphically serious, but would be reallt powerful in game.

434) IDs: Based on the aliens from the Idependente Day and other serious anthropomorphic aliens froms flims mainly.

435) Shatteres: Cocodrilian aliens. They have and extremely strong armour high HP (or whatever) and lot of stamina, but their lack of ranged attacks, speed and such make them unefficient.

436) Cryolumaca: Frozen slugs from outer space. So, yea, hovering around with ice-rays n' stuff, freesing people, It might be fun.
