Hi Five Ghost, also spelled as High-Five Ghost, and nicknamed Hi Fives, HFG, or Fives is a main character in Regular Show. Hi Five Ghost is a ghost who works alongside Mordecai and Rigby as a groundskeeper at The Park. Just like Muscle Man, he loves pranking Mordecai and Rigby, but doesn't take it as seriously. Hi Five Ghost made his first debut as a cameo character in the Pilot. He then made his official appearance in "Just Set Up the Chairs". Hi Five Ghost almost never speaks, but when he does, he was voiced by Jeff Bennett in Season One, and then he was voiced by J.G. Quintel.
Hi Five Ghost and Muscle Man are best friends when Muscle Man is around. In the episode "Gut Model", he officially told Muscle Man that he was his best friend. Muscle Man apparently likes playing basketball with Hi-Five, as shown in episodes such as "Slam Dunk" and "Temp Check". Muscle Man usually addresses High Five Ghost as "Fives".
Mordecai and Rigby
Hi Five Ghost is friends with Mordecai and Rigby, as shown in "Muscle Woman", but other times Hi Five Ghost is in conflict with Mordecai and Rigby, namely because Muscle Man does this as well, as shown in "My Mom", "The Night Owl" & "Slam Dunk". Mordecai and Rigby have never been in an argument with only Hi Five Ghost, either with Muscle Man alone or the complete duo. In "Gut Model", Hi Five Ghost was happy to be paired up with Mordecai and Rigby. Hi Five Ghost seems to be the only character to respect Mordecai and Rigby other than Pops. They are seen to be friends, as seen in"The Longest Weekend".
Skips challenged Hi Five Ghost to an arm wrestling match in "Over the Top." Later on, Skips And Hi Five Ghost pranked the rival park in "Prankless."
Low Five Ghost
In the episode, "See You There," it is revealed that Hi Five Ghost has a brother and rival whose name is Low Five Ghost. Low Five Ghost looks almost identical to his brother, except that Low Five Ghost has a bit of scruff where his "chin" would be, and wears teal sunglasses. His personality is that of a wild teenager, similar to Rigby. Low Five Ghost also has the power to turn non-ghosts into ghosts.
Hi Five Ghost's Father
In "See You There," Hi Five Ghost's father is also introduced. He remains unnamed except for "Dad" to Hi Five and Low Five. Their father is also the only one in the Ghost family who knows how to change people from ghosts back into their normal form. Hi Five Ghost and Low Five Ghost look like their dad except their dad has a beard where his "chin" would be.
