From what I can tell, Simon and Galacta Knight are at least Universal while Sephiroth and Zero are Solar System with Ganondorf possibly being Universal. Though since Simon's whole thing is having holy weapons and Galacta Knight might have holy weapons in the form of Heart Spears, they can both take out Ganondorf. I think Moon Knight is a street tier but since Simon and Galacta Knight can clear by themselves, Moon Knight's stats aren't really needed.
