Skips

 Skips works at the park. He helps Benson a lot and fixes many of the mistakes that Mordecai and Rigby make.

Personality and Traits
He seems to have an interesting and mysterious past given his immortality. Everybody relies on him to solve unnatural problems, and he almost always has the answer. There have only been a few occasions where he didn't know what to do, such as in "Brain Eraser" when, although he knew how to delete Mordecai's memory of Pop's nudity, he didn't know how to exit the video tape; as well as in "Skunked", where his best ideas were showers and coffee, neither of which worked.

Skips is often quiet and is the least vocal character of the show (other than High-Five Ghost), spending the majority of his spare time working out in the golf cart garage which doubles as his home. Despite his monotone expressions, he can be seen having a good time joking around, such as in "This Is My Jam", where he jokes with Mordecai and Rigby that he knew everything, though admits afterwards that he only knew about their plan because he was "on the can" when they were talking about it. In Over The Top, it is shown that he hates losing, let alone being cheated.

He is considerably friendly with the other groundskeepers, and seems to be good friends with Benson; convincing him to take a break in "Party Pete" due to the stress he was going through. Overall, he's always willing to assist anybody that needs him and expertise, despite how annoyed with the situation he might be.

Skips rarely ever walks or runs, but when he is punched in the face by the bouncer at Carrey O'Key's Karaoke Bar, he runs after his attacker.

Mordecai & Rigby
Skips isn't particularly close to either Mordecai or Rigby, but he is the one they come to when they cause trouble, such as in the episode Just Set Up The Chairs when Rigby releases Destroyer of Worlds despite the note apparently written by Skips warning people not to connect the wires; immediately when Mordecai or Rigby come up to him, he assumes they'd gotten into trouble and need his help. However strained the relationship may be, Mordecai (as well as many of the other characters) depend on Skips to be there for them, as revealed in the episode Free Cakewhen, upon being told that they had never thrown a party for Skips, Mordecai exclaims, "Dude, that sucks! Skips totally deserves a party." (Here Rigby adds, "And cake!"). Mordecai continues, "Whenever something goes wrong, it's Skips who fixes it. He's always there for us, no matter what." In the second season, it appears he has gotten closer to both Mordecai and Rigby, in "This is My Jam", he jokes with Mordecai about Rigby's problem and later joins them in a band; however, during the episode Jinx, he finds out Rigby is jinxed and says to Mordecai, " I'm gonna enjoy this." And runs off to punch Rigby with Mordecai; also, during the episode "Over The Top", Skips kills Rigby during an arm wrestling match because Rigby cheated; however, he is guilt-stricken at his actions and challenges Death himself in order to resurrect Rigby.

Benson
Even though Skips is employed by Benson, the two are at least friends, if not good friends. As seen in "Meat Your Maker", Skips chugs soda while Benson and Pops cheer them on. Benson has the utmost respect for Skips, as he is a hard worker and very dependable. Benson left Skips in charge while he took the day off in Party Pete. This dependability, though, did not earn Skips a birthday party, but in all fairness, Skips usually secluded himself to perform his spirit dance.

Pops
Pops and Skips do not interact too much throughout the series. They do not hate each other, often appearing in scenes together. In "Rigby's Body" though, Skips says he wishes that Mordecai and Rigby would not teach Pops those words (The word was turd).

Other Appearances
Skips has appeared in the online Cartoon Network Regular Show game, Trash and Dash. He can be picked (otherwise a marble) when 5 pieces of trash are collected, and he runs throughout the landscape, stunning any moving obstacle. Skips also appears in the online Cartoon Network Regular Show game Just A Regular Game if you notice while on the moon Skips is on the back of the cart but doesn't really do anything.
