Poseidon is a fearsome, haughty, and cold-hearted individual, shown when he mercilessly killed his older brother, Adamas. Like many other Gods, Poseidon despised Humanity and considered them nothing but filth. Poseidon is also a very taciturn and arrogant individual, viewing himself as perfect, saying that he doesn't need any supporters, even calling other Gods "useless bottom feeders" after glaring at them.
