The Guitar Ghoul was the disguise of Alvin Wiener, impersonating the real Guitar Ghoul, Nikki Starlight, who wanted to ruin her out of jealousy.

Physical appearance

The Guitar Ghoul was a humanoid, with long orange hair. He wore a purple rockstar outfit.


The Guitar Ghoul appears to be intelligent, often out-smarting Mystery Inc. Usually, this is done by taking advantage of carefully laid traps and his familiarity of his theme park, Rockin' Rollercoaster Land.

Powers and abilities

The Guitar Ghoul uses his guitar to strike electricity at his enemies.
