It looks like the hot thing to be doing these days is post about the kind of character you want to see in KI, so I guess I’ll toss out my opinion too. I’m not gonna bother with a big elaborate post about backstory or appearance though, just quick blurbs about the important details.
Puppeteer
Examples: Carl, Relius (Blazblue,) Zato/Eddie (Guilty Gear,) Chaos (UNIEL,) various characters (Persona)
I was kinda thinking gargos would be this but he didn’t really turn out that way, so it would be nice to see the archetype in another season, if we get one. It’s often executed pretty differently depending on the game and the character but the core idea is the same: controlling more than one attacking character at once. On the simple end of things you have relius whose puppet automatically moves to stay near him and is easy to keep track of, while on the more complicated end of things you have someone like carl, who actually has to manually control the movement of his puppet to get her in position to attack. Personally I think the former would suit KI more than the latter, but however it’s done I’m really curious how IG could make the archetype work in this system.
Spellcaster
Examples: Dormammu (Marvel 3,) Nine (Blazblue,) Invoker (DOTA 2,) That Little Wizard Guy From Magicka (Magicka)
This is a character archetype I’ve fallen in love with after being introduced to the concept; using different moves to build up spell components that are combined for a variety of different special moves. It’s a versatile archetype, generally having a tool for any situation, but one that requires preparation in advance to have the necessary spell components for the job. Nine’s 20(?) spells are maybe a bit much, but something like 9-10 different spells to work with could hit the sweet spot of fun, I think. Probably a lot of work to design, though.
