For a few examples, Cyberware Enderman have augments that allow you to blink around like teleportation wands. Cyberware Skeletons have augments that give you regeneration when standing under a tree, a bonemeal aura around you, etc. Cyberware Spiders have augments that let you climb walls, deal poison damage when hitting with fists, etc. Cyberware Zombie Pigman have augments that give you fire resistance, strength, etc.

Having it based on what the mob does makes little sense, considering that the mobs obviously don't need the augments in order to do any of the things listed. However, randomly giving mobs things like a fire breathing augment or one that accelerates healing in low light levels but also causes burning in the sun would be interesting.

More Cybermobs were definitely planned - but the specialized augments are something I hadn't thought of. It's a cool idea, I think I'll try to implement something like that.
