| Cream | A silent and unworthy competitor who isn't that itchy, but that doesn't really stop her from using lotion every day. | |
| Lemon | Somebody who's not very smart thinking about being a mad scientist. She also has a chance of making dirty jokes. | |
| Yellow | A happy-go-lucky individual and fast runner who likes to jump through blocks, and eliminate hostile monsters. They can also shapeshift sometimes. | |

| Violet | The latest contender to the first season, who she is usually seen as closely related to Purple. | |

| Fuchsia | A fashion savvy who has some affable confidence towards her friends. She can be angsty when something strange goes on, even as a joke. | |
| Magenta | Was once a circle, but now changed to a square to become more unique to the other competitors. Although effeminate, she can be tomboyish compared to other pink ones. | |
| White | There's a group of white circles where one of them had competed in a season. They do not talk much, but one of them is able to speak more often. | |
| Light Gray | A light-weighted competitor who can fly by using their legs. They appear idiotic on the outside, but somehow intelligent on the inside. | |
