They all wreck MHA's shit. Mostly all the protagonists are island-level or country-level and massively hypersonic. End game Micaiah and Ike are multi-continent level. Three Houses' protagonist, Byleth, is faster and can react and dodge the Immaculate One's Hoarfrost that sends down a rain of light. Rowan and Lianna from Warriors defeated Velezark, who can manipulate time and space and consume entire dimensions.
Though Fire Emblem Fates might be higher. This official character guide states that Lilith is capable of creating "Star Realms" that are localized as Astral Plane in order to aid Corrin and their group. This is referring to the My Castle hub world.
Fire Emblem Heroes is too much for MHA. Alfonse fought against Surtr, who claimed to be capable of burning everything in the Nine Realms, something that has been prophesized in ancient texts. This would also include the Realm of Dreams, a realm with an infinite number of worlds created from dreams with a separate flow of time.
