Dinko is the leader and biggest troublemaker of the alien gang. Though, he always tries to help Tommy, he always mucks things up, often because he misunderstands Tommy's words to the point of insanity. Often Dinko will go to extreme measures to solve his curiosity to these words and earth rituals. This all leads to Tommy getting punished and/or blamed for everything he and his friends do and the aliens get off scot-free. He and his gang came to Earth to make an invasion to take over the Earth so, he, Gumpers, Swanky, Scruffy and Flip stayed at Tommy's house and loved living there. It is unknown if he will make the invasion.
