Hi-Five Ghost

==Brief Summary==
Hi-Five Ghost (simply referred to as "Fives" or "HFG") works alongside his best pal Muscle Man at the park. Fives rarely talks, but when he does, he uses a high, quivery voice. Although he is Muscle Man's best friend, he does not seem to share in the rivalry with Mordecai and Rigby to the extent that he does, although he does tend to get into fights with them at times. Fives has a brother named "Lo-Five Ghost" who seems to be a criminal until Muscle Man and Fives bailed him out, and graduated from the police academy in Gut Model. Fives does not seem to be embarassed by Muscle Man's "my mom" jokes, considering he encourages him by high-fiving. Fives has the ability to turn into a ball-shaped shield in order to protect someone from a projectile item, which was revealed in Gut Model when he protected Muscle Man from getting burned by the grease monster. Fives is mostly shown with one hand on his head, although he is sometimes shown with two hands, as Lo-Fives is also. Fives was voiced by Jeff Bennett in the early episodes, but is currently being voiced by JG Quintel.
