Nichole is a unsuccessful impostor, who faces constant challenges in attempting to take over the underwater ship. As the evil version of Yellow, she finds it difficult to make any significant progress in their nefarious endeavors. She's constantly walking around with her children Sewer and Sushi. Sewer is placed on her head while Sushi walks besides her.

Sushi is a cold thoughtless girl and Sewer is a maniac energetic boy. Both of them are about 15-16 years old.

Nichole hates everyone.
