Wakana Sonozaki

The ClayDoll Dopan also known by her human identity Wakana Sonozaki, is a character in Kamen Rider Double. At first she was sort of a neutral character but by the next half of the series she becomes one of the major antagonists.

Wakana Sonozaki
Wakana was raised to become the key element in her father, Ryubee Sonozaki's plans for the Gaia Impact after her brother Raito Sonozaki's death. Working as a DJ at the local Wind Wave (ウインドウェーブ, Uindo Wēbu) radio station, she hosted the Wakana's Healing Princess (園咲若菜のヒーリングプリンセス, Sonozaki Wakana no Hīringu Purinsesu) show and gained a fanbase as a result. While she puts up a shy and kindly persona on the show, her true personality is the complete opposite.

Out of all of the members of the Sonozaki Family, she is the least involved with the Gaia Memory business, as she was doted upon while growing up. After encountering Philip, Wakana begins to have second thoughts about being a Dopant and discards the ClayDoll Memory. It is returned to her by her father, who is aware that she did not lose it as she claims; he later decides to bring her into the family business after Kirihiko's death and is the one chosen to view the effects of the Xtreme Memory on the True Gaia Memory. Before this, Wakana also becomes one of Shinkuro Isaka's unwilling experiments after he modifies her Gaia Driver, subjecting her to more of her Gaia Memory's influence and its short term side effects showing her compatibility with its powers.

After trying to run away with Philip, her father takes her to the Museum's true base of operations. With her personality changed entirely due to giving into the corruption of the ClayDoll Memory, Wakana now runs the Museum and the Digal Corporation, bent on bringing Philip back to the Museum by any means to fullfill his part in the Gaia Impact. She is also given the Prototype Organic Information Controlling Organ Body Gaia Progressor (有機情報制御器官試作体・ガイアプログレッサー, Yūki Jōhō Seigyo Kikan Shisaku Tai Gaia Puroguressā), a device based on the Xtreme Memory designed to evolve her into the godlike ClayDoll Xtreme (クレイドールエクストリーム, Kureidōru Ekusutorīmu) to prepare her for the Gaia Impact so she can become one with the planet's vast knowledge. When the Gaia Impact seems to succeed after Philip is thrown into the source of the true Gaia Memory, becoming a living Gaia Memory, Wakana loses control when Philip is removed from her body, causing an explosion that destroys the Sonozaki estate. However, in midsts of the blaze, Wakana's body is carried off by Kazu to the Foundation X research facility.

ClayDoll Dopant
As a member of the Museum, Wakana is able to transform into the ClayDoll Dopant (クレイドール・ドーパント, Kureidōru Dōpanto), enabling her to produce gravitational energy shots, as well as the ability to reform her Dopant body after it is shattered into thousands of pieces. Unlike other members of her family she wears the buckle in reverse.

ClayDoll Xtreme
After having the Gaia Progressor spliced into her body by the Gene Dopant, Wakana's Dopant form evolved into the god-like ClayDoll Xtreme. While armed with tendrils and exponentially more power than the ClayDoll Dopant, she becomes a being like Philip with access to the true Gaia Memory, much like CycloneJoker Xtreme. Due to this evolution she became unaffected by Double's Prism Break Maximum Drive effect to negate regeneration and can call on this form at will when in her regular Dopant form.
