Scorch Supernova (voiced by Brendan Fraser) is a heroic alien on a mission to rescue captured babies from the Gnarlachs. He rescues them just in time before the Gnarlachs wake up. Scorch returns to Planet Baab where he is known as a famous hero and works at BASA with his older brother Gary (voiced by Rob Corddry). Gary's son Kip (voiced by Jonathan Morgan Heit) is a big fan of his uncle Scorch. Soon, Gary receives a message from Lena Thackleman (voiced by Jessica Alba), the head of BASA, that Scorch will be sent to the "Dark Planet" (the Baabians' name for Earth) due to a SOS call. Scorch decides to go to the Dark Planet, as he already made a press conference and contacted his sponsors. However, Gary opposes as Scorch is not serious and no alien has ever returned from the Dark Planet. After further arguing, Gary finally says that he won't be helping Scorch and quits BASA before Scorch himself fires him. Gary then goes home to his wife Kira (voiced by Sarah Jessica Parker) and Kip only to find out that Scorch has already gone to the Dark Planet, while Kip is watching it on live TV in excitement.
