Tsukasa Kadoya

Kamen Rider Decade (仮面ライダーディケイド Kamen Raidā Dikeido, Lit. Masked Rider Decade)is the main protagonist of the upcoming crossover story, Skylar Space-Time x Kamen Rider Decade. He is an arrogant young man who has the power to transform into the nine Kamen Riders that precede him. His logo features the numbers 453 and 145 below the bar code. These digits correlate to the English letters A, C, D, and E to form the word "DECADE".

In the Crossover
In the crossover, Tsukasa crosses over into Skylar's world and discovers remnants of the terrorist organization, Dai-Shocker, have appeared there. While there Tsukasa loses the ability to transform into his normal Decade form, and instead directly to Decade Complete Lovely Form. He meets up with Skylar, and to his chagrin, works with the young boy.
