Mr. Meeseeks (voiced by Justin Roiland) is the name of all the Meeseeks summoned by activating a Meeseeks Box. The Meeseeks appear in the fifth episode of the first season, "Meeseeks and Destroy". They are known to inhabit planets across the universe.[1][2]

Personality
Mr. Meeseeks exhibits a friendly, cheerful, and helpful demeanor; willing to assist the one who brought him into existence, however possible. Ideally, Mr. Meeseeks will dispatch the simple task given to him, and disappear shortly after its completion. However, if given a task that is outside of Mr. Meeseeks' capabilities, he will not be able to cease existing. This unusual lifespan will cause Mr. Meeseeks' attitude and mental state to worsen dramatically; the relatively long and tortuous existence quickly driving him to violent behavior and outright insanity. Meeseeks who have been spawned in tandem are seen to distrust and attack one another as their sanity decays, although they will continue to attempt any possible solution to their original purpose, including collaboration with other Meeseeks. The psychological and physical (discoloration of skin, hair growth) symptoms of existence upon Meeseeks can manifest in less than 24 hours. According to Jerry's original Mr. Meeseeks, two days is "an eternity" in Meeseeks time.

Trivia
"Look at me!" and "I'm Mr. Meeseeks" are two lines each Meeseeks repeat almost every time they start or end a sentence.
As Meeseeks begin to age, their appearance becomes more and more rugged with spotty body hair and patches of darker blue that appear like stains.
In the unlikely, but possible, event that a Meeseeks cannot help complete the task assigned, he will, in time, go mad and resort to drastic measures to carry out his assignment (even if it means resorting to violence and killing the person he is helping).
It's possible for a Meeseeks to summon another Meeseeks and give it orders. One Meeseeks was even observed summoning multiple Meeseeks at once without issuing a vocal command.
The original concept for Mr. Meeseeks was a neon taupe. However, the concept did not resonate well with viewers.
A Mr. Meeseeks made a small cameo in "Mortynight Run", giving someone gaming tips at Blips and Chitz. Once the player wins the game, the Meeseeks vanishes.
In the Japanese dub for Rick and Morty the Meeseeks are voiced by a woman.
Mr. Meeseeks' blood is pure white
Dan Harmon has stated that he will force Mr. Meeseeks into season 3.
The concept was likely based on an episode of Doc and Mharti about a comic book series called Scud: the Disposable Assassin. It's about Scud robots, which one can hire to kill someone. After the person is killed, the Scud robots self-destruct.
