I was thinking something similar.
An unlocking spell that would make every lock in the hemisphere never be able to close again.
A low tier water spell causing a Noah level great flood.
A wind spell not only scouring all matter from a massive area, but turning that matter into shrapnel that kills everything for hundreds or even thousands of miles.
He's quite literally too powerful to cast a weak spell, lol.
And yet he's still weaker than the mc from Shinka no Mi, who caused the spacial reality around himself to tremble and show signs of breaking just by clutching his hand too hard. And later on willed multiple dead souls back to life while in the world of the dead.
