Jason Dark

Jason Dark is one of the primary antagonists in Tenko and the Guardians of the Magic. Unlike his sister Jana, Jason does not wish violence upon the Guardians, and is later revealed to harbor romantic feelings for Princess Tenko.

History
A descendant of a former Master Guardian, Jason Dark and his twin sister Jana were recruited by Hikita Tenko and trained as his apprentices. When a newcomer was appointed as Master Guardian over Jason or Jana, the twins were outraged. Although Jason wished to reason with Hikita, Jana convinced him to put their heritage above all else. Together, the siblings attempted to steal the magical Starfire Gems, though they were stopped by Hikita, Steel, Bolt, Hawk, and the newly-appointed Princess Tenko.

Jason then joined his sister in New York City, where they sought out the Opal Gem. After their hired thug Mel botched the mission, the Dark Twins tracked down the young girl Ali, who was in possession of the gem. Jason took advantage of Ali's vulnerability, manipulating her into siding with the twins. However, Tenko later convinced Ali to join the Guardians of the Magic, and drove the twins off with the Opal Gem.

Powers and abilities
Jason is in possession of the Ruby Gem, which enables him to summon forth his weapon of choice: the Mesmer-Disk. This weapon functions both as a shield from oncoming attacks, as well as an instrument to hypnotize his opponents. He often used this weapon to overpower his foes' minds, allowing Jana to attack them with her beams of fire.

Like all of Hikita Tenko's students, Jason is a skilled athlete and magician.
