Mechikabura in his old age is stronger than everybody (And he one shot Xeno Goku). In his youth he was unfathombly above anything the characters have seen. But of course that's really vague. But who knows, with the crazy shit DBH has done I wouldn't doubt some greater feats. That and it took the Dark Dragon all his 5-D/6-D (Depending where you have the transcending the multiverse feat at) to restore Mechikabura's youth.

They created everything in it, created the laws of the Demon Realm, made magic work as oppose to physics etc. It is very likely they made the concepts as well. Demigra was going to create his own multiverse, after destroying the current one and everything in it so it is very likely he can create/destroy concepts.
