Who would win in a fight - every FNF character or 1 billion lions?

We've had Pokémon and we've had the sun, but what about every FNF character? This includes mods, not just the base game.

I'd say every FNF character, simply because Shaggy exists, but there's probably other ways they could win. All the lions would be working together and all the FNF characters would too, which means that Corruption and Pibby Corruption characters would be there too.

What do you guys think?
