His Persona, Gemzygus, is a floating creature made of Zyform Crystals that all combine to make a large creature. It's sunglasses are a straight rectangular shape across his head and it has two floating hands.

"Jokezee" is the same as Gemzee, but instead of wearing sunglasses it wears the Phantom Thief Joker's mask.

Backstory
Not too much is known about Gemzee's origins, but what we do know is he banded with Jack and Ruby to create the Gem Guardians, who Jiggly would trust to gatekeep the castle's Great Gem Gate. Gemzee's had a friendship with Glitchy prior to the events of Part 1, however he doesn't always show his care for Glitchy. He awakened his Persona, though its unknown how.

Abilities
Gemzee on his own can't do too much. He can turn his sunglasses into a boomerang, though that's mainly it. His true power comes in the form of his Persona, Gemzygus. Gemzygus can control the earth, primarily through attacking with crystals summoned from the ground. Gemzygus has access to other abilities, such as firing off beams of electricity, dropping off bombs filled with energy, and hovering.
