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".

In these 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
