Dokinchan (known as Doquín in Spanish adaptations) is an orange-red germ character from the Anpanman series, serving as Baikinman's primary antagonistic partner. Her design features a white facial area extending to her nose, green eyes, small red cheeks, a single antenna, pink shoes, white hands, and a long tail resembling Mushibaikinman's.

Her personality blends selfishness, demanding behavior, and greed with occasional kindness. She frequently bosses Baikinman around, ordering him to fetch objects or people, yet demonstrates underlying care for him. Dokinchan typically flees first when confrontations turn unfavorable. A defining obsession is her intense infatuation with Shokupanman, sparked during a bread theft incident. This drives extreme efforts to win his affection, including maintaining a room filled with Shokupanman merchandise and indulging in romantic daydreams.

Key relationships define her narrative:
- With Baikinman, she acts as an assistant despite frequent rudeness, reflecting a complex partnership with mutual care beneath surface conflict.
- Her younger sister, Kokinchan, engages in typical sibling rivalries intensified by their competition for Shokupanman's attention.
- Shokupanman remains her unrequited romantic focus, pursued through comedic and disruptive extremes.

Historically, Dokinchan wielded a specialized staff capable of enlarging objects with one end and reducing them with the other. This tool appeared in limited episodes before its usage ceased. She utilizes a pink UFO for transportation, occasionally deploying it to hold hostages for Baikinman's schemes but more frequently for non-combat tasks like carrying baskets or flowers.

Her character songs include solos like "I am Dokeen" and "Doki Doki Dokinchan," duets with Baikinman such as "Dark Magic," and seasonal themes with Shokupanman. Localized names include "Dokeen" (English/Tubi), "红精灵" (Chinese), "짤랑" (Korean), and "Spark" in an unreleased Cinar dub.
