Just watched Side Affects, and I'm making up sick aliens. Frostblast, Wildmutt, and Four Arms aren't listed.
Sickliens[]
Grey Matter: Lighter grey, tinted green. His gills are snotty, and he can't think very straight.
XLR8: Looks the same. Wheels are sticky.
Upgrade: Looks the same. Occasionally electricutes.
Diamondhead: Lighter colored diamonds. He is softer.
Ripjaws: Looks lighter. Can't swim without breahting very well.
Ghostfreak: The black lines are snotty green. When he turns intangible, snot drips everywhere.
Cannonbolt: TBA.
