DBZ (I feel like they fight multiple gods)

Yup. DragonBall Z and Super both kept adding higher and higher echelons of deities and otherworldly beings, starting with the Kais, right up to a being that sits over multiple universes. Of course, Goku tries to pick a fight with every single last one of them, with very little regard for the existence of multiple of said universes.

Seven deadly sins

I'm gonna be real here: I have no idea if that tracks or not, and I did my level best to pay attention. The story makes so little sense, with all the "rules" getting thrown out and replaced with more nonsense, every five episodes. They easily could have wound up at a lower power scale at the end than when they started, and you'd have no way to know for certain. That said, they do drag top-dog spiritual entities into the mix near the end.
