Christopher is a Banana Guard who does not have any banana peel on his head and arms. He has brown hair and a navy-colored badge with a crown on it on his body with a long strap under the badge. His spear is slightly different than a regular Banana Guard's spear.
Not much about him is known, but as seen in the episode "Rattleballs," he becomes happy when he learns that Rattleballs died and says, "Ooh, wow. Cool," which shows that he dislikes Rattleballs. The death was actually a fake death organized by Princess Bubblegum.
