Bakfufu is a sort of childhood friend of Sergeant Tarere but they got separated in adolescence. He joined the military a bit earlier but due to being taken out for a bit of time for 'upgrades' he ended up a bit behind the curb in basic learning but those upgrades gave him a massive boost in skill. His spooky prosthetic eye on the right side helps him aim. He's an alien frog. (https://www.deviantart.com/mlknoll/art/Keronian-OC-Bakfufu-775269878)
