Sinspawn (Final Fantasy X)

Sinspawn are creatures born from Sin in Final Fantasy X. They are a vital part of Operation Mi'ihen, as the Crusaders use the Sinspawn to call out to Sin, which would inevitably be drawn to them. You fight five Sinspawn in the game: Sinspawn Ammes (A large anemone-like creature), Sinspawn Echuilles (a jellyfish-esque beast), Sinspawn Geneaux (A shelled plantlike monster with large tentacles), Sinspawn Gui (a large armored arthropod), and Sinspawn Genais (a pallet-swap of Sinspawn Geneaux)
