>>32670709Speaking as someone who's extensively knowledgeable on FE lore, Anankos isn't a particularly big deal.
1) Considering his lack of access to weapons that aren't (draconic) breath attacks, he is instantly forced into at LEAST a stalemate with any Fairy-type Pokemon. Furthermore, most "competitively viable" Fairies can just wear him down. The likes of Xerneas, Mega Mawile, and even Azumarill come to mind.
2) Any Pokemon with "godlike" power should be able to fight him on at least even terms, if not outright overwhelm him. Arceus is a sure bet, with access to any type in the game (including the aforementioned Fairy type), excellent firepower, amazing bulk, and the ability to recover lost health (which is something that the "Silent Dragon" doesn't have access to).
Even barring Arceus, though, pretty much any cover Legendary should be able to clean the giant spiked dragon dildo out, regardless of form.
Also, considering Anankos's greatest "claim to fame" would be invincibility until pierced by a divine blade like the Yato, I'm pretty sure that he'd also get roflstomped by the Muskedeers.
Come back with an actually impressive FE villain.
