Dorodoron

Personality
Dorodoron tends to be quiet and can be a bit cowardly, though he is also competitive, as evidenced by his annoyance with Michiru and Kaoru when he thinks they are trying to outdo him.

Etymology
Dorodoron probably comes from 泥々 (dorodoro), which can mean muddy or dirty. Ironically, the word ドロドロ (dorodoro), meaning rumbling or booming, has the same pronunciation.
