Mr. Mucus, also known simply by his surname, Mucus, is the mascot of the Mucinex brand of decongestion medicines and the main antagonist of the brand's commercials. He wanted a place to call home out of the insides of his human hosts, but he is quickly evicted with the proper dose of Mucinex.
He was originally voiced by Roger L. Jackson (who also voiced Ghostface in the Scream franchise, Mojo Jojo in The Powerpuff Girls, Wizeman in NiGHTS: Journey of Dreams, and Nohman in Zone of the Enders series) from 2004 to 2014. He was later voiced by T.J. Miller (who also played I-R0k in Ready Player One) from 2014 until his firing in 2018 over allegations of sexual assault. He is currently voiced by Jason Mantzoukas (who also played Nadal in The Dictator, Mr. Ross in Regular Show: The Movie, Steelbeak in Ducktales (2017), Jay Bilzerian in Big Mouth, Scarecrow in The Lego Batman Movie, and Scrappy-Doo in Velma) since 2018.
Biography[]
Old Mucus[]
Surprisingly, Mucus has gone through many changes since his first appearance.
In his earlier appearances, he was portrayed as a single squatter who stubbornly refuses to leave a person's lungs until they took Mucinex. He was then shoved away by a large box of Mucinex only to return inside someone else and made different attempts to make sure he could not be moved, including attempting to duct tape himself down. Once, he took the form a giant western outlaw only to be quite literally blown away by Sheriff Mucinex.
Later, he became married and had a son named Junior (used to advertise children's Mucinex). It is also revealed that he has an enormous extended family, all of them equally as stubborn. In his last appearance to date, he has a new friend called "Nasal Sweller", who resembles a bouncer, but he is also defeated by Mucinex.
The New Mucus[]

The new version of Mucus.
Recently, the new version of Mucus has appeared with a drastic new look and a new voice.
This new Mucus has a more updated personality and attire and is seemingly more of an annoying and troublesome jerk than a squatter.
One major difference is that, unlike the first version of Mucus, humans are fully aware of his presence and he exists in the real world. People are usually seen trying to get rid of him as he will not leave them alone. In his ads so far, he tries to convince a woman not to use Mucinex, was forced to blurt out a spoiler alert in a crowded movie theater, and tries to join a man for work without permission for "Taco Tuesday".
