Basilisk

A basilisk is a giant serpent, also known as the king of serpents. It's a magical beast that Geminis breed.

Description
Basilisks are silver in color with large amber eyes and an expandable collar of white spikes around their necks. Basilisk skin is armored like that of a dragon's, which deflected spells cast upon it. Basilisks shed their skin at intervals, like all other snakes, when it grew.

Abilities
Light Vision: Basilisks can fire light/photons from their eyes, causing advanced beams of light to blast their opponents.

Personal Darkness: Basilisks can manipulate their darkness and dark energy to effectively manipulate one's own visibility by absorbing light, creating a personalized field of shade, or wielding it for specialized techniques like attacks and defense.
