Exodus is proud of his fighting skills, proud of his superhuman strength, proud of his heavy-duty armor, and especially proud of his sharp purple horn on his forehead. He feels that he is upholding the history and traditions in every challenge he faces, from defending the universe to playing space games, and he accepts nothing less than glorious victory at each one. He considers any kind of loss to be a crushing blow to his honor, and so he strives to be the very best at every astronomical competition imaginable, whether great or small. Predominantly, he always insists on winning by the rules. To Exodus, there is only one thing in the Psymonster World worse than losing – and that is why he is being a dishonest cheater.
He is a big, obese green battle alien with a sharp purple horn on his forehead, a dark teal mouth with a teal tongue, sharp teeth, one red eye, a black armor, fingerless armored gloves, and armored shoes.
