Seamars is a fox-like alien that has a long white beard and wears a top hat. He wears a body suit that has what they seem to be three manometers on it: one on the left sleeve, another on the right, and the last on the chest area. His suit also has boots.
After Enel landed on the moon, Seamars found and attacked Enel and First Lieutenant Spacey in a crater. Seamars attacked Spacey first and skewered him with an electrical spear nearly killing him. The Space Pirate then tried to skewer Enel, but Enel did not even react at first. Enel then attacked and defeated Seamars.
