Minus Four

“Negatory!” - Minus Four, on some occasions

Who is Minus Four?
Minus Four is a female number. She appeared in the second season, alongside Yellow Four. She is the red version of Four, with a negative sign.

Appearance
Throughout the series, Minus Four has a red body, pink limbs and crimson red eyes. She has a minus sign next to her, which is her pet cat, Minusy. Minus Four also sprouts claws on several occasions.

Personality
Minus Four is a brute. She is always negative and has an abrasive personality to her character. She always thinks everything is bad and thinks everyone deserves to burn in Hell. She often pushes people to their limits, which results in Minus Four being grounded occasionally.

However, in contrast to her negative personality, Minus Four has a deeply emotional side to her character. Starting from the eleventh season, Minus Four had realised the error of her ways, and is looking to be a more friendlier person. It is only by Season 12 that Minus Four finally started crying after ten seasons of her screen time! Minus Four will also feel sympathy towards other characters. For instance, in “Don’t Wake Up Fourtle”, she feels bad after accidentally waking Fourtle up from his nap after she gets him back to sleep.

Trivia

 * Minus Four is the oldest Four, as she is 37 years old. She was also born on April 4, but she was born in 1984.
 * However, it is revealed in “Big Girls Don’t Cry” that Minus Four is Four’s adopted sister, meaning Minus Four and Four aren’t related.
 * It makes sense, considering that Four’s mum is 34 years old, and must have gone to the Underworld and asked MF’s dad if she’d like to adopt Minus Four.
