Fender first appears when he takes some pictures of Rodney Copperbottom's first moments in Robot City, whereupon he tries to scam Rodney by saying that he must buy the photo for $50.
He later meets Rodney again in Robot City and the two become friends. Throughout his role, Fender is whimsical and sometimes melodramatic. Fender has a "sister" named Piper Pinwheeler with whom he has a sometimes one-sided sibling rivalry.
At the Bigweld Ball later in the film, he meets a female robot named Loretta Geargrinder and has a crush on her. During a moment of carelessness, Fender is taken to the chop shop, where he loses his legs.
He puts on a replacement, only to find out his new waist once belonged to a female robot. With no time to find another replacement, he uses the new legs to escape the chop shop.
