Chimera is very cool and kind of feels like what Spinner should have been, continuing the trend where his name follows his Quirk, just like AFO. He has similar issues to Spinner.
Also, Chojuro's villain name, Quirk, and appearance are based on the Chimera of Greek mythology, a monster resembling a hybrid of different animals (a lion, a snake, and a goat, and in some versions, a dragon, too). His final defeat even echoes that of the mythological creature, as the hero Bellerophon managed to kill the Chimera by forcing a lump of lead down its throat, just like Shoto defeated him by forcing ice down his throat.
According to his concept art, Chojuro's design is a hybrid of an eagle, a wolf, a cow, and a snake. He can also breathe fire and seems friendly with Nine, which is cool.
Also has a simialr issue to Spinner-
Due to his powerful Quirk and intimidating appearance, Chojuro was ostracized and subject to discrimination, which led him to resent and hate society.
One day, Nine saved Chojuro from authorities and asked him to join his group, explaining that he will create a world where those with the strongest Quirks would rule over the weak and powerless, that way no one would be called
