Get them all and you'll get the Master of Mimicry trophy. They can be extremely powerful if used right - but you'll have to track down the enemies that can teach you all of the skills first. These Enemy Skills are powerful, high-quality moves, and in FF7 Remake they only cost an ATB bar charge, not MP. It has the more straightforward name of Enemy Skill in FF7 Remake, as it did in the original, and takes the form of a Command Materia that, when equipped, means you can learn certain skills when they’re used on you by enemies and then use them yourself.

In other Final Fantasy games, this skill might be known as Blue Magic - the ability to cast magic skills learned directly from enemies. It’s back in Final Fantasy VII Remake, and is used to give the player access to some combat abilities that are otherwise unnatural to Cloud and crew. The Enemy Skill materia is an absolute FF7 classic.
