Galeem killed Sonic in the opening of world of light though which would imply he's much more powerful than Tabuu, and that Sephiroth is more powerful than Sonic.
Kirby is still more powerful than all of them though.

Don't think about power levels in smash they don't go by their canon strength, even in this cutscene it doesn't make sense sephiroth one shot galeem but cloud was able to over power him even though he was taking in master hands
