There's a pretty big streak in the Kirby series between Return to Dreamland and Star Allies where pretty much any new character added had floating hands (Magolor, Taranza, Haltmann, etc.)

Amazing Mirror also has that one boss guy with floating limbs

honestly it's a pretty general staple of kirby, i remember mr shine and mr bright all the way back from adventure

Pretty much every Star Fox goes here

IDK Mr shine and mr blight dont seem to have separate limbs
