Diane Marie Rosie Johnson is one of the main characters of the hit TV show, Black-ish.

She is portrayed by Marsai Martin.

Character Info[]

She considers herself to be smarter & more mature than her twin brother Jack.

Diane and Jack are the Johnson family's eight-year-old twins at first, now fourteen years old. Diane is gifted and talented. She thinks she has all the answers but has yet to develop a filter to put them through. Although she is one minute older than Jack, she likes to think she is smarter than her twin brother by ten thousand minutes.

Personality[]

Throughout the series, Diane morphed from a sassy, intelligent, normal little girl to a scheming, calculating, dangerous, eccentric, scary, and intimidating adolescent. On numerous occasions, Diane has scared her family, relatives, and peers because of her bizarre personality. She finds delight in bullying her brothers, being right, gory and bloody scenes, weapons such as nunchucks, spying on others, insults, and chaos in a household. She believes friendship and sickness is a sign of weakness and is recognized in her family for being scary and threatening arson. and she can be mad and happy but she is like her twin

She’s been described as greedy, mean, spiteful, vindictive, and petty. There is unknown history between her and Charlie Telphy. Junior described it as complicated, and Diane hinted that the start of their feud was caused by something Charlie may (or may not) have done. The latter is terrified of Diane and tries to warn Dre of her capabilities. According to Viveca A. Fox, the sound of Diane's name makes the light go out of his eyes.

She is also a conspiracy theorist in the most ridiculous of situations and is able to twist any situation for her own advantage. In the time when Diane began her menstrual cycle, she adopted a more nasty, dangerous version of herself where she promised to hurt Jack in his sleep and burn down the house.

Her very essence in a room is enough to make anybody in the Johnson family jump; Bow, Dre, Ruby, Junior, Zoey, respectively.

The episode (Black Like Us) shows another side of Diane when she expresses her wish to be not as dark as the rest of her family. When she accidentally got O.J.’d in her school photo and her family made a big deal about it, she perhaps demonstrated a more fragile side to herself despite of her brazen front.
