Mega Man Zero/Enemies and bosses

Regular enemies
The screenshot and main stage columns refer to the stage where the enemy drops a Cyber-elf.

HP stands here for "Hit Points", not "Health Points": robots don't have "health".

Notes:

In the following two stages no regular enemy drops a Cyber-Elf, so you can freely use the "knight" (-nite) and "Mettaur" (Mor-) cyber-elves:
 * Neo Arcadia Shrine
 * Neo Arcadia Core

Traps
These enemies cannot be destroyed, and they have to be dodged. They can be temporarily stunned.
 * Ray blade
 * Top Gabyoall

Sub-bosses
These enemies cannot be dodged, and they have to be defeated.
 * Quicksand Mixer
 * TechTwister
 * Carrybee
 * Metarook
 * Pantheon Ace

Hierarchy

 * 1) Copy X.
 * 2) The Four Guardians: Harpuia, Phantom, Leviathan, Fefnir.
 * 3) The Maverick Hunters: Herculious Anchortus, Hanumachine, Maha Ganeshariff, Blizzack Staggroff, Anubis Necromancess, Aztec Falcon.
 * 4) Reploid bosses: Rainbow Devil, Asura Basura, Pantheon Aces, Hittide Hottide (the "giant mechaniloid"), Guard Orotic (the "factory boss"), Pantheon Core (the "train engine"), a Golem.
 * 5) Pantheon reploids.
 * 6) Other robots.

Etymology
The name of the animal-like bosses is in the form "animal + attribute", but unlike in the  series, here the names are further modified, both in the Japanese original and in the English localization.
