Cyberdemon


 * For the Cyberdemon in Doom 3, see Cyberdemon (Doom 3).

The cyberdemon is perhaps the most formidable enemy in classic Doom. This monster first appears as a boss at the end of Doom level E2M8, and re-appears in the secret level E3M9, and also on E4M2, E4M6, and E4M7. The cyberdemon also appears on the retail box cover of Doom II, and is used sparingly throughout that game.

The Doom II manual of the PC version describes the monster in the following way: ''A missile-launching skyscraper with goat legs. 'Nuff said.'' The Doom manual, on the other hand, does not list it, presumably to make its climactic appearance in E2M8 a surprise. The PlayStation and SNES manual for Doom does however make mention of the cyberdemon: ''Half unfeeling machine, half raging horned devil. This walking nightmare has a rocket launcher for an arm and will definitely reach out and touch you. Make sure you're loaded for bear before you get to this guy.''

Combat characteristics
It attacks by firing barrages of three rockets. It has 4000 hit points and does not receive splash damage from explosions, making it fairly difficult to kill. It is also the fastest moving monster in the original game (The lost soul's charge attack not withstanding), and second fastest in Doom II (after the arch-vile).

Cyberdemon rockets behave exactly as the player's rockets, although they cannot damage other cyberdemons. Furthermore, the cyberdemon and the spiderdemon take only direct hit damage, and are immune to all blast damage. Therefore, a greater number of rockets is required to kill these bosses than might be expected, and they must be direct hits. The cyberdemon is given a higher probability of performing his attack than other monsters, causing him to launch volleys of rockets at a high frequency. The cyberdemon does not have a melee attack. In common with other monsters, although the cyberdemon is shown with his rocket launcher in his left hand, the rockets emerge from his middle.

PROTIP: To kill the cyberdemon, shoot at it until it dies.

Data



 * 1) This table assumes that all calls to P_Random for damage, pain chance, blood splats, and bullet dispersal are consecutive. In real play, this is never the case: counterattacks and AI pathfinding must be handled, and of course the map may contain additional moving monsters and other randomized phenomena (such as flickering lights). Any resulting errors are probably toward the single-shot average, as they introduce noise into the correlation between the indices of "consecutive" calls.
 * 2) Assumes that the target takes a direct hit from each shot.
 * 3) Assumes that direct hits are possible, which does not occur in any stock map.
 * 4) Hardcoded exception to infighting prevents all damage.

Appearance statistics

Doom 64
The cyberdemons in Doom 64 have not gone through many changes except that they have darker colored skin, and are slightly stronger and much larger. The Doom 64 version of the cyberdemon is notable for having the ability to lead its shots, making it an even more formidable opponent (the cyberdemon's third rocket is usually fired at the player's anticipated position rather than the player's current position). The rockets they fire also leave smoke trails.

Trivia

 * In a PC World article, the cyberdemon was voted as #16 of the top 47 "The Most Diabolical Video-Game Villains of All Time".
