if i was designing 000 ids of the beta kids id probably do:

june: poise tremor with a huge lean towards burst dps with animations close to r&p ryoshu cuz big hammer, with a big aoe tornado as a enhanced skill 3

rose: i dont have magical girl don but from my understanding you could change the visuals and status names to be beetween her light player abilties and going grimdark and youd be done it fits perfectly

dave: poise rupture, basically a cinq id with t corp mechanics

jade: i have no idea. other than just going "well she has a gun" her space powers would be completely unlike anything weve seen in limbus

less concrete ideas for the alpha kids but id say jane would be tremor, jake would be charge dps, dirk would be poise sinking with synergy with dave, roxy would be charge utility
