Dokeen, known as Dokinchan in Japanese, acts as Baikinman's primary partner and secondary antagonist in the *Anpanman* franchise. She resembles an orange germ or alien entity, featuring a white face, green eyes, a red nose, pink shoes, a distinctive single antenna, and a demon-like tail.

Her personality mixes selfishness, childishness, and greed, frequently demanding Baikinman fetch food, items, or people. Despite her antagonistic role, she sometimes exhibits kindness, particularly towards Shokupanman (Bread Head Man), for whom she holds an obsessive romantic infatuation. This crush drives her to extreme efforts to win his affection, including maintaining a room filled with his posters and plush toys. Her loyalty to Baikinman wavers; she often bosses him around yet retains underlying care, and she usually retreats first during confrontations with heroes.

Dokeen has a younger sister, Kokinchan, with whom she shares a rivalry over Shokupanman's attention, though their relationship remains generally amicable. Her equipment includes a pink UFO used for transportation and occasional hostage-taking. She formerly wielded a dual-pointed staff capable of enlarging or shrinking objects, though this tool was phased out in later episodes.

Her name varies across adaptations: "Spark" in unreleased English dubs, "Dokeen" in the Tubi English dub, "Jingle" (짤랑) in Korean, and "Red Lips" (红精灵) in Chinese.
