Last boss in Siren's Grotto: Dissension (CHALLENGE). Can not be attacked in the regular instance even if you kill all of the other bosses. At least not that I have seen.
To open his cage you have to beat the Gen'ra & war council in challenge mode as well as the Tavalon overlord in challenge mode to unlock his cage failure to do both will not unlock this boss to fight.
