Muscle Man

Mitch "Muscle Man" Sorrenstein is a main character of Regular Show. He is one of the groundskeepers of the Park. He is a green, strong and obese monster and/or disfigured humanoid, who is often seen with his best friend, Hi Five Ghost. Muscle Man made his first debut as a cameo character in the Pilot, and then made an official appearance in ""Just Set Up the Chairs"." Muscle Man is voiced by Sam Marin.

Appearance
Muscle Man is a green man with shoulder-length, greenish brown hair. He wears a long-sleeved grayish-blue shirt, dark gray pants, and black shoes. In ""Under the Hood"," it is shown that he wears socks, but the pants cover them. In ""Trucker Hall of Fame"," when he was a kid, he still looked the same, but with freckles. As a teenager, he was tall,skinny, and had zits. He is 5"8 due to the book of the park workers and their jobs that was shown in "Exit 9B"

Personality and Traits
Muscle Man is a type of monster and/or disfigured humanoid that works in the park along with Mordecai and Rigby. He is also quite unhygienic, reeking of body odor as evidenced in ""The Night Owl"." As of the episode ""Gut Model"," he has worked for the park for 5 years. Although Benson considers him to be hard-working, Muscle Man (along with Hi Five Ghost) has been revealed to do more work than Mordecai and Rigby, despite the fact that all four of them are slackers. In ""Muscle Woman"," however, they tend to slack off more than Mordecai and Rigby. In ""My Mom"," it's shown that he has a lot of friends, most in which love his constant "My Mom!" jokes, which everyone else at the park gets annoyed with. He's best friends with Hi Five Ghost, who loves his jokes. Ignorant yet clever when it comes to pranks, he's always either insulting Mordecai or Rigby, or trying to prank them (ex. "My Mom", "See You There"). But he does care about his mom as shown in "My Mom" when he got very angry when Mordecai and Rigby made fun of his mom. In response, he brought his brother, John, to give Mordecai and Rigby a punishment for ridiculing their mother.

Despite being obese and lazy, there is a story behind Muscle Man's nickname (as revealed in ""Peeps""). In the episode, he said that he is losing muscle mass from the stress Peeps put on him, so he may have muscle mass. He also loves to mess around with Mordecai and Rigby.

Muscle Man has developed a massive ego that is seen throughout the series especially in ""Exit 9B"," where he purposely has the biggest signature.

In ""Out of Commission"," he got 70% of his butt covered in 3rd degree burns.

Skills/Habits

 * My Mom Jokes - In many episodes, Muscle Man has made "my mom" jokes. Instead of the iconic "your mom" jokes, Muscle Man flips it and ends up making fun of his own mom.
 * Strength - Despite being obese, Muscle Man is shown to be very strong (hence his name), enough to easily hold off several armored security guards and kick off a man's head in ""Big Winner"," and almost beat Skips in arm wrestling in ""Over the Top"," He has even been shown to be able to lift huge boulders, throw fully grown trees, and lift a small building, carry it a distance and hurl it at a moving vehicle, thereby making him the 2nd Strongest in the park next to Skips in ""Starter Pack"."
 * Pranking - Along with his best friend, Hi Five Ghost, they are master pranksters who prank Mordecai and Rigby often. He even saved the park in the episode ""Prankless"" when he tricked Gene and made him surrender.
 * Trumpet Player - In ""This Is My Jam"," he and Hi Five Ghost are able to play the trumpet together; though, Muscle Man only blew into the trumpet as Hi Five Ghost was doing the fingering.
 * Gut Model - In ""Gut Model"," Muscle Man is a very good "model" when giving off his gut looks.
 * Temporary Tattoos - Muscle Man obviously likes getting temporary tattoos. Since ""Trash Boat"" and ""Muscle Woman"," he has two tattoos: One of a dog and one that says "STARLA".
 * Horrible Secret Keeper - Muscle Man cannot keep a secret for even five seconds, as shown in ""Fuzzy Dice"."
 * Physical Defense - He can protect himself from harm like when he was stabbed by the Giant Spider, as shown in "Terror Tales of the Park II"

Starla
Starla is Muscle Man's girlfriend that is seen in ""Muscle Woman"." Muscle Man has been dumped by Starla twice, presumably for not being willing to share his feelings. However, by the end of the episode, they are back together and are still be in a relationship. Starla has had many relationships with other men. In "Fancy Resturaunt", Starla is still seen as being Muscle Man's girlfriend, and invites him to have dinner with her parents. At the end of the episode, Muscle Man, Starla, and Starla's parents eat dinner at Wing Kingdom.

Hi Five Ghost
Hi Five Ghost is to Muscle Man as Rigby is to Mordecai. They are usually seen together in the episodes. He usually gives a high five right after Muscle Man says a "My Mom" joke. In ""My Mom"," the two seem to slack-off as much as Mordecai and Rigby.

Mordecai
Out of the two protagonists, Mordecai seems to dislike Muscle Man more. He is annoyed by the constant "My Mom" jokes and even confronts Muscle Man about it in ""My Mom"" Besides that episode, there is not much interaction. Muscle Man does throw his shirt at Mordecai in ""Caffeinated Concert Tickets"," but that may have been an accident rather than a direct confrontation. He may have been doing this just so that they would not have to do his work. In Season 3, they become nicer and friendlier to each other, help each other with problems and Mordecai even tells Muscle Man that him and Rigby are his friends in ""Fancy Restaurant"," after offering to help him.

Rigby
Rigby seems to like Muscle Man slightly more than Mordecai. He likes to hang out with him in ""My Mom"," and seems to get along with him very well, yelling "Ohhhhhh!" along with him at the taco truck. They do have some confrontations though. In ""Meat Your Maker"," he goes to say Muscle Man pushed him at a party (though Mordecai quickly says Muscle Man was not even there). By the end of ""My Mom"," Rigby goes on to say how he hates Muscle Man. In ""Death Punchies"," Muscle Man is forced to be look out, even though his eyes were punched out by Rigby. They also hang out in ""The Night Owl"." In Season 3, Rigby and Muscle Man become more friendly to each other and at times help each other with problems. In "Bad Kiss", Rigby said that he owes Muscle Man a lot of money.

Benson
Benson trusts Muscle Man far more than Rigby and Mordecai, as established in ""Appreciation Day"" and ""My Mom"." He does fire Muscle Man though in ""Don"" and ""Under the Hood"." Benson also seems to understand Muscle Man and his antics, as demonstrated in ""But I Have a Receipt"" and ""Free Cake"," not yelling at Muscle Man when he put "My Mom" on the list. He does not confront Muscle Man when he turns off the lights and unzips his pants in ""Free Cake"," simply saying, "It's not that kind of party, Muscle Man." In season 3, he started to get a little annoyed with him.

Skips
They do not talk much in the series but seem to be good friends. Like in ""Under the Hood"," he gives him saucy chicken wings from Wing Kingdom.

Pops
Pops tries to help Muscle Man to learn how to be fancy, but he fails, in ""Fancy Restaurant"." As shown in ""Prankless"," he greatly respects Pops because when he was going to prank Mordecai by putting his bed on the ceiling, it fell on Pops and he nearly died, thus Muscle Man said that he would never prank again until Benson convinced him.

Margaret and Eileen
Margaret & Eileen have only ever interacted with Muscle Man once in ""Do Me a Solid"," when Eileen, Margaret, and an uninvited Muscle Man were having Ice Cream Sandwiches at Mordecai and Rigby's house.

Death
Death Is Muscle Man's Rival Since "Death at Eight"

John
John is Muscle Man's older brother, who was seen in ""My Mom"" and ""Trucker Hall of Fame"."

Muscle Dad
Muscle Dad is Muscle Man's father who is seen in ""Trucker Hall of Fame"."

Scottie
Scottie is the person in charge of getting people to the Crash Pit. When Muscle Man and Hi Five Ghost find a car to run into the Crash Pit, he gets people to watch.

Bobby
Bobby works at the nursery helping people carry heavy plants. He and Muscle Man are friends. He thinks Muscle Man's "My Mom" jokes are hilarious.

Jimmy
Jimmy works at the TV Warehouse and owes Muscle Man something. He got fired for giving him a TV so that they can beat The Hammer. He is then killed by The Hammer afterwards at The House.

Taco'Clock Worker
He seems to have a friendship with the Taco'Clock worker. He also laughs at Muscle Man's "my mom" jokes.

Police Officer
He is apparently friends with the police officer that appeared in "My Mom" as he reminds Muscle Man of the dangerous driving highway and they seem to already know each other.
