Circubite

The name Circusic is a blend of circular (“round”) and music, reflecting his shape and abilities.
His design is partly inspired by sirens: his music charms and subjugates others.
It was initially speculated that Circubit might be a corrupted version of Iris, but this has been disproven.

Natural abilities:

Superhuman speed: as a sphere, he moves faster than most figures; roller skates further enhance his speed.
Body dismemberment: can separate parts of his body, but cannot do so if the body is damaged.

Controlled weapons:

Spiked balls: summons and throws pink spikes; can create small ones or explosive ones that detonate on impact.
Musical notes: generates pink notes (likely via his headphones), using them for mind control. Example: he subdued Cirtunda, forcing him to attack members of the Big Giant Circles Group (Circumuscle and Spheer).

Unique abilities:

Dual form: can exist both in corrupted form and in a pure state (as Circusic), while retaining his identity. After an attempted purification by Iris (Episode 2 of Season 2), he temporarily takes on a pure form, but later becomes corrupted again.
Immunity to purification: partially resistant to complete eradication; even after purification attempts (eg, by Orange), he continues to exist.

Key traits:

Mischievous and sinister: enjoys scaring other characters (jump‑scares), including Teal and other protagonists.
Ironic: often makes sarcastic remarks (eg, he mocks Iris for hair loss).
Manipulative: devises schemes to deceive others (eg, he tricked Dub into believing that the heroes had kidnapped Cyanide).
Overconfident: highly values ​​his own music, calling it “mesmerizing”.
Indifferent to chaos: uses his powers to control others purely for his own amusement.
Independent: acts according to his own will, ignoring authorities.
With a glimmer of empathy: in Episode 4 of Season 2, he shows sympathy for Teal and advises her to “always do what you think is right,” which helps Teal gain the trust of other heroes.

Periodically experiences traumatic flashbacks about his pure alter‑ego Circusic (short film "Circubit's Reoccurring Memory"). During these visions, Circubit's eyes glow blue, and he appears anxious and irritated.

Initially, he is a servant under the boss named Dub.
In Episode 1 of Season 2, he is teamed up with Teal (Cyanide).
By Episode 4 of Season 2, it becomes clear that Circubit no longer obeys Dub's orders and openly disregards his authority (in a conversation with Teal, he calls the boss an “asshole”).
At the end of Episode 4 of Season 2, he forms an alliance with Reaper to achieve his goal — to defeat Iris.

Circubit is a male corrupted sphere of medium height and build, colored in shades of pink. Key visual details:
