Nicholas Andrew Michael Shawn Nathan Wanya "Nicky" Banks is Will's little cousin and Uncle Phil's and Aunt Viv's youngest child. And he is also known as nice, imaginative, confident, heroic, outgoing, loving, affectionate, sensitive, adventurous, nurturing, daring, respectful, efficient, well-mannered, mild-mannered, independent, caring, honest, altruistic, exuberant, loyal, strong-willed, headstrong, arrogant (occasionally), whiny (occasionally), negative (occasionally), naive, attentive, thoughtful, hard-working, assertive, nurturing, well-meaning, argumentative (occasionally), noisy, kind and aggressive (occasionally).
Nicky (Played by Ross Bagley from Season 5 onward) is born to Philip and Vivian on February 22, 1993, towards the end of the third season. Except by one episode, when Carlton calls him "Nicholas", every member of the family calls him by his nickname, Nicky.
The character was primarily used as a plot device, often adding motivation for other characters, comic relief, or an emotional punch to the show's storyline. In the fifth season, Nicky grows from a newborn infant to a preschooler, which is common in television series and soap operas. In the first episode to feature this change, Jazz expresses amazement while Will just stares uneasily into the camera.
- His last four middle names are the names of the Boyz II Men members; he was middle-named this way after they performed at his christening.
- He is the only main character who does not appear in the first episode as he was not born until Season 3
