I honestly feel as if a lot of these names, synonyms, and adjectives should be changed since like 60% of them are never used so I thought the best course of action would be to make new ones so we have more options to name our moves!
Names:
-Pistol
-Magnum (It doesn’t matter if it’s already an Adjective people can already make weirder names.
-Snipe (Specifically for Beam Attacks)
-Gun
-Pierce (we already have it as an Adjective but again wierder names can exist then Piercing Pierce)
-Purgatory (I know it’s an Adjective because Zoro used it with Purgatory Onigiri but it sounds better as a Name when like this)
-Phoenix (As long as Familiars/Magic Animal Summons aren’t planned)
-War
-Colors (red, blue, green, etc.) (suggested by @Figure)
Adjectives:
-Greater
