Vocal

Vocal is a captain of Rockers. It has a sweet voice, every Rocker likes him without any doubt. The violin it's carrying with gets used only as nothing but a weapon.

Ragnarok Online II
In RO2, Vocal returns as a boss monster. However, it is colored red in the game to make it stand out as opposed to its original green color in RO. It also holds a leaf stem instead of a full leaf like other Rockers.
