Final Fantasy VII Remake Abilities

Abilities are greatly expanded in Final Fantasy VII Remake. The original's abilities were basically Commands. Things such as Steal/Mug, Manipulate, etc were materia that provided extra commands.
Now on top of command abilities returning, characters have their own unique weapon abilities learned from their weapons. Enemy Skills are also now under the "ability" label, rather than a kind of spell. It does lend into why there is so few Command Materia in the game. There is more than enough abilities now to make up for it. And frankly I like the more powerful Enemy Skills costing a ATB charge...rather than precious MP.
Below is a complete listing of Character, Command, and Enemy Skill abilities, as well as how to acquie them.
