Kamen Rider W (pronounced Double) premiered in late 2009 following the finale of Decade. This is the first series to feature two people, Shotaro Hidari and Philip, who transform to a single-body Rider. The two work together as "half-boiled" detectives in the ecologically-minded city of Futo to solve crimes perpetrated by humans who use special USB flash drives to transform into superpowered monsters called Dopants. Joined by Kamen Rider Accel, Philip's relation to the both the Dopants and the mysterious Sonozaki Family are brought to light. This series aired for 49 episodes and had three movies; it was the first of the Heisei Kamen Rider Series to premiere in the fall, rather than in the beginning of the year. ~ from Wikipedia
And it is awesome. I desperately enjoyed this series, on the level of Buffy the Vampire Slayer, Star Trek and Firefly. I possibly consider this to be my favorite TV series ever, but that could just be the new-ness of it.
