– Darkness Cerberus
Darkness Cerberus, full name being Mythic Beast Darkness Cerberus, is the leader of the Mythic Beasts under the leadership of Chaos Empress, Eris. With the power over the element of Darkness, Cerberus can do many things.
Cerberus is a large dark brown, almost black in some parts, three-headed canine. His tail is shaped to be like a snake and has chains around each head. Each head and dark gray eyes, matching Chrystal's eyes.
Unlike most multi-head creatures, Cerberus acts as one being. The personality being the same for each head. Cerberus is very similar to Chrystal, quiet, doesn't speak unless told to, and rarely shows emotion. Though, Cerberus tends to show a little more emotion than Chrystal. Cerberus is also very wise in his own way, able to give Chrystal rather insightful advise.
As the Mythic Beast of Darkness, Cerberus is able to manipulate all forms of darkness including dark energy.
- Darkness manipulation: As the wielder of the Element of Darkness, Cerberus can summon, create, control, materialize and absorb shadows and darkness energy to accomplish various effects.
- Umbrakinetic combat: Cerberus is able to use his darkness in combat.
- Dark energy manipulation: Cerberus is able to manipulate dark energy.
- Darkness empowerment: Cerberus becomes stronger during the night.
- Mythic Beast sense: As a Mythic Beast, Cerberus has the power to sense when one is nearby. However, when he is with Chrystal, he uses most of his power to shield her so no one can try to hurt her since it has happened in the past. When he uses his power, he is unable to sense when another Mythic Beast is nearby.
- Predator instinct: As a canine, Cerberus possesses keen predatory instincts.
- Enhanced senses: With three heads, Cerberus' senses are tripled.
- Leadership skills
- Night vision: As a canine, Cerberus is capable of seeing in the darkness.
- Darkness adaptation: Cerberus can easily adapt to dark environments.
- Mythic Beast blockage: If Cerberus is using his power to shield Chrystal, he is unable to sense if another Mythic Beast is nearby as just using his power to shield Chrystal drains his energy and takes his concentration away making him only focus on Chrystal.
- Cerberus is the most powerful of the Mythic Beasts, but keeps this fact hidden.
