Decka was kidnapped and put in a cage by Mayor Coleman so he could have an endless supply of gold, but when Mayor Coleman fed him meat he transformed in to his primal form in which caused him to eat everything in sight. Echo Echo defeated him by letting him eat the Echo Echos which are made of silicon which his species can not eat because it is poisonous to them.
After he returned to normal, he says that he will never again return to Earth and will tell the others so they won't come back either, much to the mayor's greed.
He is also shown to have a bad temper and get frightened easily.
