Cyberdemon 

The cyberdemon is usually seen as the most powerful enemy you encounter in doom. His first appearance was in Ultimate DOOM the the last stage of episode 2 in Tower Of Babel.

The cyberdemon has goat legs but one of them is metallic or perhaps robotic. His weapon is a rocket launcher that replace one of his hand. His tactic is to mindlessly shoot 3 rockets in a row at the player which deals tremendously high damages even at the lowest difficulty. However this is his weakness because a player with some experience will be able to dodge the rockets easily because of the simple attack pattern it uses.

In DOOM II, in the stage named GOTCHA!, this stage is meant to show a battle between a cyberdemon and the final boss of Ultimate DOOM, the spider mastermind. The cyberdemon usually always win unless the player interfer.

The cyberdemon makes a come-back in DOOM III where he is the final boss of the game. Despise his incredible damage rating, if the player defeats it the usual way, the cyberdemon is quite easy to vanquish.

Oh so this is the last stage of episode 2... uh? Theres nothing... wait... WHAT IS THAT!?

The Cyberden and Go 2 it in Final DOOM plutonia is the stages with the most cyberdemons.

Cyberdemon 

The most powerful enemy in the Doom series, also a signature. The Cyberdemon is an enormous bull-headed demon with mechanical add-ons such as a torso with wires, a metallic foot, and above all, a big fat rocket-launcher.

The Cyberdemon makes a return in Doom III, but apparently plays a very significant role in the game (no, you don't play as him, but he has a major purpose in the storyline). Also the Cyberdemon looks bigger & badder than his predecessors.

Cyberdemon 

20 feet half robot-half demon that shoots rockets from the DOOM video game series. It doesn't take any splash damage, and most probably the strongest enemy in the game. First appears in the last level of the second episode from the first game as a boss, but becomes a regular enemy in later levels and games.

"The Cyberdemon. Shoot it until it dies."

Cybermonk 

A monk in present day who can proficiently use modern computers and technology, somehow has access to advanced scientific equipment in their monastery that would normally be difficult to obtain and spend their time assisting heroes in catching bad guys with their technological skills.

They have a strange tendency to show up in high-tech espionage movies starring Dennis Rodman. Some are known to dance.

The cybermonks in Double Team have been collecting information on Rome for over 500 years, and helped Quinn find his missing daughter.

The cybermonks in Simon Sez can dance.

Cybermonging 

The act of simply monging out on the internet with other people. This can be in a chat room or in a voice conference but usually very little constructive communication occurs.
This activity is usually the result of being under the influence but is not strictly limited to this state of mind.

We all sat in the same chat room online...not saying much...not doing much...just Cybermonging
