Also, here's an interesting scenario for you:
Imagine that the Cyberdemon's cables in the abdomen are not cables
Imagine that it's a body horror caged within, meekly showing it's horrid face
Imagine that when you "kill" a Cyberdemon and it blows up, you merely release the abomination
Spoiler:UPDATE:
No Tyrant is a Tyrant without big fancy claws!
