The mosquito is not an arachnid butler, despite its appearance as a short old man with a large pointed nose used to extract blood from victims. It can transform into its form from 800 years ago, which may suggest it possesses greater strength than it appears. However, this transformation requires high-grade blood. The mosquito has a sense of honor and allowed Maka, Black Star, and Kid to leave during their fight since they were running out of time and had impressed him with their performance.
