As the Liar Dopant, the user can spit needles and is armed with the Lie Speaks (ライスピークス Rai Supīkusu), a staff with a large speaker in a shape of a giant mouth that can shoot energy blasts, the Liar Dopant's signature move is converting any lie they say into their Lie Needles (ライニードル Rai Nīdoru), forcing whoever it hits to fall under the Dopant's deception.

Main article: Sachio Sawada

The main user of the Liar Memory was Sachio Sawada (沢田 さちお Sawada Sachio), a street calligrapher and poet who used the Liar Memory to become the Liar Dopant, referred to in urban legends as the Radio Tower Clown (電波塔の道化師 Denpatō no Dōkeshi). Though he was paid by Yukiho to help Jimmy win the Fuuuuuutic Idol (フーティックアイドル Fūtikku Aidoru) competition, he turned on her after she failed to pay him his ideal amount, revealing the ruse in front of Jimmy. Once his cover was blown, and his being a fan of Wakana Sonozaki's radio show used against him, the Liar Dopant was defeated through the combined powers of Kamen Riders Double and Accel, with Double dealing the final blow using CycloneJoker's Joker Extreme.


In the music video for "Love♡Wars", the Liar Dopant makes a cameo as he fights the Kamen Riders.
