Carl (カール Kāru) is Johnnie Rico's best friend and highschool classmate.
During the graduate party after the football game, Carl encouraged Johnnie to tell Carmencita his feeling. However, another boy told everyone go to the beach to have a spree. Because Johnnie had drank too much, Carl drove him to the beach. They had a conversation about the future on the car.
Next night, Carl brought a floppy, which contained a video footage of Mobile Infantry fighting against Arachnids, to visit Johnnie. In Johnnie's room, Carl stated he was going to join the military and asked Johnnie if he wanted to join as well before Carl left Rico's house.
