Merlow is a Sonic Fan Character (FC) known for being a psychotic, fourth-wall-breaking mercenary.

While he looks like a Gizoid (the same robot model as Emerl), he is actually a mysterious, wisp-like entity possessing the robot shell. This gives him the unique ability to summon and weaponize Wisps at will.

This character is created by DestructionSeries, a fan character lore: a chaotic, fourth-wall-breaking "Deadpool-esque" entity who possesses a Gizoid body and controls Wisps.
