I do love Cait Sith and I love Final Fantasy when it's just full of weird little guys. But... admittedly I'm more partial to Anise's playstyle due to the nature of the Tales of battle system meaning Tokunaga here is just constantly beating the shit out of enemies. Everyone else in that game just uses swords or bows or whatever but it is just so fun and over the top to have a character's weapon of choice be "a giant doll". I want more action RPGs to do that! Whether it's a giant doll or something else you would not expect to act as a weapon.
If I'm missing any other similar characters or even just weird weapons please post them I must know.
