Gishgar is a ghost guppy who sometimes has nothing but mischief in his mind. He's very mean, but he's also a bit helpful. He lurks in the shadows, and can be quite a bully to Harksher. Although he enjoys scaring people, he'll only do so if it was Cofaribubble who comes up with scary pranks.
Gishgar has purple skin, dark lavendar spiky hair, red eyes, black pupils, a wicked smile, and a tail the same color as his hair.
