the green bits are places I might make prose edits on.
"the Jet Plane": firstly, it's the Jet Plane Pokemon! secondly, it's a little cliche.
"Latios's movepool is also quite unique, in the sense that": way too conversational for an analysis imo. i talk like this in vm/ pm, but i certainly wouldn't write an analysis in this tone of voice :p
"yet struggles to gain": 'gain a fire-type move'? yeaaaah, odd. probably just something like 'struggles to dent steel-type foes as his best fire-type move is hp fire'
i'd also insert he gets access to the rare moves Recover, Trick, and Memento so as to not leave less familiar readers wondering what precisely is so special about those three moves
"His defenses are also low": surely you can find a synonym for 'low', haha
"releases a strong attack": again, odd wording
"Regardless of these disadvantages": i honestly can't explain why, but 'drawback' just seems like a better word here.
so yeah, was this helpful? :)
