Exodus is a competitive, purposeful, ambitious, forceful, and energetic Psymonster who 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 magnificent 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.
- He slightly resembles the Purple People Eater from the 1988 science fiction comedy film, Purple People Eater.
- Exodus is one of the eight Psymonsters who have one eye (the other seven are Helmodon, Sinclops, Hypnodon, Fuzukeen, Deceased, Headphonical, and Quartz).
- He appears to have a horn on his forehead, similar to the way the unicorn has a horn on its forehead.
- He is the only Psymonster with gloves that are fingerless.
- Like Thunderhorn, Exodus has a horn on his forehead.
