Hades is the Gods' representative in the seventh round of Ragnarok, replacing Buddha following his betrayal in the previous round, going up against Qin Shi Huang. Hades seems to be a very sophisticated and quiet individual while also being a very respected and feared God among the Greek Pantheon, seen when Ares immediately gives up his seat to him at his order[1] and when all the Gods stood at attention upon him entering the arena.
