Zack Quinn

Damien Quinn, also known by his duel persona Enigma, is a high school student and is one of the main characters in Kamen Rider Retro.

Powers and Abilities

 * Genius-Level Intellect: Damien has a formidable mind. He has shown an ability to quickly adjust to new situations and predict the actions of other riders almost perfectly.
 * Original Bugster Virus: Being a Patient Zero, Damien was host to the virus for a prolonged period of time. This allowed the virus to fuse with and alter his DNA granting him Rider and possibly even Bugster-like powers and abilities that, by standard, requires external intervention to acquire.
 * Natural Game Disease Immunity: Unlike the other Riders, Damien can utilize the Gamer Driver and Rider Cartridges without the need of the compatibility surgery. Also, his immunity is absolute, unlike the other Riders' acquired immunity which can still be overwhelmed by a large dose of Bugster virus, as he was unaffected when using the Mighty Combat Cartridge for the first time.
 * Cartridge Creation: As Patient Zero of the Bugster Virus, the progenitor of all the Rider Cartridges and Bugsters, he can use the Bugster Virus in him in conjunction with certain blank Cartridges to create new, stronger forms for himself. This causes the Bugster Virus in him to evolve and become even stronger, which made Damien as Retro become stronger in return. Damien demonstrated this ability twice so far in the series with the creation of Mighty Combat and Maximum Carnage. He can also modify Cartridges to a degree.
 * Dual Personalities: Due to the Bugster Virus in Damien's DNA, he has two different personalities, which can take him over when using Mighty Combat.
 * Increased Physical Strength: In at least one occasion, the spontaneous activation of Damien's Bugster infection allows him to exert great physical strength without transforming.
