Zack Quinn

Damien Quinn is a high school student and is one of the main characters in Masked Rider Valiant. He transforms into the Masked Rider Valiant.

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.
 * Hand-to-Hand Combat: Damien has shown himself to be a skilled fighter, being able to easily take on Bugster viruses as a civilian.
 * Skilled Gamer: Damien is a masterful gamer, particularly in terms of RPG gaming. He has extensive knowledge of games in other genres, including Wild Shooter and Heat Bike and can adapt easily when playing a new game. These skills are greatly enhanced when he enters a state of emotional rage or frustration, as shown when he effectively, in separate occasions, outmaneuvered both Genesis and Shooter who are both at their Level 3 forms while Damien is only on Level 2. Furthermore, if his Genius Gamer persona is 100% active, his gaming skills skyrocket at a frightening degree evidenced on how despite being only at Level 3 he managed to overpower a Bugster who is a Level 30, stating that one of gaming's thrills is figuring out how to defeat stronger opponents.
 * 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 Gamers 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 Knight Fantasy Gamer 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 Classic become stronger in return. Damien demonstrated this ability twice so far in the series with the creation of Knight Fantasy and Knight Legacy. He can also modify Cartridges to a degree.
 * Dual Personality: Due to the Bugster Virus in Damien's DNA, he has another personality, which can take him over at random times.
 * 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.
 * Bugster Ability Restriction: One of the functions of Level 0 Cartridges. Damien can seal certain abilities of Bugsters who are in his game area, such as host possession.
 * Level Regression: Thanks to Level 0's power being over nothingness, by touching a Bugster, he can degrade their Levels to reduce their powers.
 * Teleportation: Damien has shown the ability to teleport himself.
 * Self-Digitization: Damien is able to traverse between the real world and the digital world.
 * Data Mimicry: Damien can travel through the cyberspace by transforming into computer data.
 * Respawning: Damien can simply respawn himself, each time he is defended.

Weaknesses

 * Level 0: As stated by it's name, Level 0 is the weakest level among all the levels, making him extremely vulnerable to any type of attacks, even the orthodox attacks can deal great damage on him. This disadvantage can be covered by utilizing advanced-level Cartridges, as well as his Respawning ability.
