Here's the place for Gloria move set brainstorming
I don't have much to add, but here's a link to an old discord discussion
Maybe she'll be floaty like peach. Maybe lasers like palutena
B: a blast that knocks down. Hold for a floating orb that stays for a bit.
C: an upward light beam like palutena? Basically her king.
Air B: maybe a down beam like her jack
Super: heal full health? Gloria has one of the lowest healths in yomi so she might have 5. If she heals to full health, I don't think that's be too terrible. If she has 6 then maybe.
