Arceus was also injured by a meteor. Given Arceus is literally the god of Pokémon, this would mean every Pokémon would be forced to be weaker than that meteor, including universe creators and destroyers (which includes Arceus hilariously enough) and many other Pokémon who have feats far above that meteor.
This is a classic case of the low-end feat not fitting with even basic feats in the verse, like Kratos struggling to cut down a tree when even his most basic feats far outclass it.
I actually do think Lugia needs to be looked into, with its ability to fight Hoopa. From what I can tell Hoopa's Varies Tier exists solely to not scale that Lugia to anything else in that movie, and it's kind of silly given that Lugia was chosen across all dimensions from a likely infinite list of legendary Pokémon to face the evil Hoopa and put up a far better fight than the legendaries at the start.
Only issue I see is that the Lugia in the Orange Islands fared worse against the legendary birds than the Hoopa movie's Lugia did against Hoopa, which seems to be a matter of different individuals having different strengths. I mean we already scale
a Pikachu to legendaries that should far outclass it.
The literal creators of time and space, so they're pretty much covered.
