Col. Kroptman

Kroptman is a firm sphero rebelling against FunFrock during his reign. He became the colonel of the rebels on Rebellion Island. Kroptman was captured during their assault on the Okojo pass, which would lead them to the Northern hemisphere of Twinsun.

When Twinsen arrives to Rebellion Island he is given the task to free the Colonel. A commando helps Twinsen to get into the fort which guards the pass and where Kroptman is being held. Freeing the Colonel eventually enables Twinsen to reach the Northern Hemisphere himself.

After Kroptman is freed by Twinsen he escapes together with the rabbibunny commando that had guided Twinsen to the fort. They both disappear.
