--Scar to Gumball in Alkmer's shadow
Scar McGriffin is a commando of the ACU (Alkmer Commando Unit) who was sent by Major Z to stop Dark-Shadow. Since then he has befriended Gumball, Darwin, and Penny.
Scar has red fur that is stained with blood from his continuous battle with Dark-Shadow along with a hole in his ear from another battle with Dark-Shadow and a scar on his eye (The scar is how he got his name). Scar also has red markings on his body and a black X on his chest that he got when he first joined the ACU.
Gumball Watterson- He and Gumball are great friends and will always help out eachother. Like getting Penny
Penny Fitzgerald- Scar and Penny hang out a lot too, because most of the time Scar is trying to get info of what Penny likes to help Gumball get Penny.
