it's slightly smaller and weaker than your average cyberdemon. to compensate for this, it has vastly increased mobility and is somewhat more aggressive.
actor name is "cyberjumper" if you just want to play around with it
if you want to actually use it for anything (like a miniboss, or even just as a base for some other monster) go ahead, i'd be honored, just mention my name in the credits somewhere. uploaded as an attachment because it's less than 2kb i mean really
Spoiler:edit: oh my gosh i just fought 5 of them at once in the middle of map13 using the plasma rifle
it's so nerve-wracking when one of them jumps over your head while you're dodging shots from the others.
