Dopants

The Dopants are the antagonists in the fanfictional Kamen Rider Series Kamen Rider: Double Detective. Dopants are actually normal humans who use Gaia Memories. The Gaia Memories are aspects of the true Gaia Memory, the knowledge of everything on the Earth. These were originally accessed due to Charlie's link to the Gaia Memory by means of the Gaia Library. But after he was taken from them, the Gardenar Family uses a strange temple underneath their mansion to access the Gaia Memory. They then sell these to the highest bidder or to common criminals, both types used as guinea pigs to study the Gaia Memories as part of the Gaia Impact project. The name comes from the English words "dopant" & "doping".

Dopant Gaia Memories
A Gaia Memory is a mysterious device resembling a USB flash drive that contains all of the Earth's knowledge of what it represents. This enables its user to become a Dopant, or in some special cases, a Kamen Rider. Every Gaia Memory is adorned with the first letter of its name, stylized to reflect the powers it imbues on its user. For example, the Injury Memory (acquired by Simon & Charlie) resembles a broken bone in the shape of the letter I. Each Memory also features a button which when clicked causes the Memory to loudly declare its name; while this is traditionally done immediately before inserting the Memory by Riders & Dopants alike, it is unclear if it is actually mandatory to activate the Memory's powers. In order to transform into a Dopant, the Gaia Memory is first inserted into a device called the L.C.O.G (the acronym for "Living Connector Setting Operation Gun", though normally called called a Connect Shooter, which then produces a USB port-like tattoo on the user's skin called a Living Connector. Whenever the Gaia Memory is pressed onto the Living Connector, it enters the user's body & transforms the user into a Dopant. Use of a Gaia Memory without a Living Connector is possible, but the side effects of doing so are nearly fatal.

This direct insertion will eventually drive its user insane from its addictive influence, which is why special belts called Memory Drivers have been developed for use by high ranking members of the Museum to filter out these & other side effects. This has the side affect of visibly weakening the Dopant's powers. Due to this, Museum members use some of the strongest Gaia Memories to more than compensate the loss of power.

To defeat a Dopant, a Kamen Rider has to use one of his Maximum Drive finishing attacks to eject & destroy the Gaia Memory, resulting in what is called a Memory Break. Evolved Gaia Memories, however, require a direct strike on its location within the Dopant's body to execute the Memory Break without the risk of killing the user. If the Dopant does not have a Living Connector, a Memory Break will not occur, however the Gaia Memory will still be ejected from the user's body. In order to defeat a Dopant that uses a Memory Driver, the belt must be broken in order to defeat the Dopant & cause the Memory Break.

Other Dopants use T2 Gaia Memories, 26 special Gaia Memories developed by Foundation X based on Cecelia Gardenar's findings. Though originally in the possession of Edric Barlow before giving it to another member of the Foundation to take to their headquarters, the T2 Gaia Memories end up in the possession of mysterious terrorist group NEVER. Unlike the original Gaia Memories, these memories appear to have some sentience, injecting themselves into people who are compatible with them (Watcherman & Santa-Man) or causing a Living Connector to appear on someone's skin (Queen). Other than their leader, each member of NEVER uses a T2 Gaia Memory based on one of Kamen Rider Double Detective's Gaia Memories.

Gardenar Family
The Gardenar Family is an aristocratic family in Windy City who created the organization Museum. When his son Nicholas died & was reborn as an avatar of the true Gaia Memory, Sebastian used his organization to produce & distribute the Gaia Memories in the criminal underworld, resulting in the Dopant crimewaves as part of a bigger plan to invoke the Gaia Impact. With the exception of Nicholas & Cecelia, they each own special golden Gaia Memories, allowing them to assume Dopant forms with the use of a prototype Gaia Driver belt, preventing the Gaia Memory's corruptive nature. Because they have belts, they are easily identified as "Commanders" by Simon & Charlie.

Sebastian Gardenar
He is the head of the Gardenar Family & leader of the Museum, acting as a godfather in the organization.

Background

Before his son Nicholas Gardenar's death, Sebastian was an archaeologist who bought the grounds his estate was built on after finding deposits of fossils & relics that eventually form the collection in the Windy City Museum. It was then he found a point where the planet's consciousness dubbed the "Gaia Memory" resides & brought his family to see it.

However, when his son Nicholas fell into the "fountain" of the Gaia Memory & died, but was somehow resurrected by the planet's powers, Sebastian began his plan for the Gaia Impact & used the Evil Tail charm he acquired overseas as a means to overcome the fear that would go with sacrificing his own family to achieve it. As a result, Sebastian went mad & saw the entire city of Windy as his kingdom & he refuses to let his vision of it be ruined, even by his own wife & children.

Part in Story

Sebastian spends most of the series in the Gardenar Manor rarely having any part in most Dopant crime waves. He appears as the Terror Dopant usually when necessary & involving the Museum affairs. When the Gaia Impact plan commences, he invites his family (mainly Samantha & Shroud) to beg for forgiveness as Harmony will become all-powerful through the Gaia Impact, but Samantha refuses & fights against her sister instead while Shroud takes her leave. He then sacrifices Nicholas (Charlie) once more into the Gaia Memory to make his daughter Harmony one with the Earth, he is confronted by both Kamen Riders.

While Kamen Rider Accel as the AccelTurbuler destroys his Terror Dragon, Simon is able to retrieve Charlie's mind & then his body from the aspects of the Gaia Memory in ClayDoll Xtreme to transform into Kamen Rider Double Detective CycloneJoker Xtreme in order to defeat the Terror Dopant & destroy the Terror Memory, along with most of the Gardenar estate. With Sebastian's mind still broken from years of planning, he enters the still burning ruins of his home, glad that he had finally initiated the Gaia Impact. He dies in the blaze, thinking of the good times he had with his family before he discovered the Gaia Memory.

Personality

Sebastian was at first a responsible & caring father figure toward his family but after Nicholas died & using the Evil Tail, Sebastian grew mad thinking only about his plans of the Gaia Impact regardless of the dangers on the people of Windy City including the Dopants (who he sees them as research specimens) & his own family (appearing to be protective of it while he really has no qualms about using his son & youngest daughter). He does not seem to consider the Kamen Riders a threat to his plans, instead using the data off of them as a means to perfect his plans for Harmony before turning his attention to regain Charlie & complete his plan to initiate the Gaia Impact. The only living thing that Sebastian appears to care about at all is his cat Mick. When he is defeated & the Gaia Impact somewhat fails, he starts to remember who he was & remembered the better times with his family.

Dopant Form
With the Terror Memory & the prototype Gaia Driver, Sebastian can transform into the Terror Dopant, who can increase the fear in his victims to maddening levels. He has also shown to be able to use this outside his Dopant form. He can also summon the Terror Field to burn his victims or teleport himself & others across long distances & project his power into his headdress to create a Barong-like creature familar known as the Terror Dragon. However this leads the Dopant vulnerable to attacks as he is left powerless.

Samantha Gardenar
The eldest of the Gardenar children who runs an IT company called the Digal Corporation, which serves as a front for Gaia Memory production & distribution.

Personality

Her father, Sebastian Gardenar strictly raised Samantha to believe that their family is superior to all others & that they are destined to rule the world. This loveless upbringing caused her to grow up secretly hating her father, often taking the resulting rage out on her younger sister Harmony Gardenar, serving as fuel for her own ulterior motives of taking over the Museum to prove herself to her father to be its ideal successor. She also has a tendency to kill her boyfriends if they do not live up to her expectations. Although Samantha initially spares Nevel Rattan due to his capabilities, even marrying him & letting him be a part of the Gardenar Family, she kills him when he threatens the Museum's livelihood. She has no problems executing Nevel as she had never loved him. Later, she pays regular visits to Dr. Mark Leitner to improve her Dopant form & focus on her plans for the Museum. After he is almost defeated by the Kamen Riders, she begins to show that she cares for Leitner's well-being, which is likely to be genuine attaction to the doctor.

History

While Allen & Simon Holmes infiltrated a top secret installation, seeking the "Chosen Child", whose powers were being used for evil, the alarm sounds & Samantha in her Taboo Dopant form along several Masquerade Dopants to fight Allen who transforms into Kamen Rider Skull. Allen's fedora is damaged by her during the fight. She later appears again as the Taboo Dopant shortly after Charlie is rescued from the central chamber of the Gaia Tower & Allen gets a shot wound. When Simon & Charlie transforms into Kamen Rider Double Detective for the first time, she flees just before the building explodes.

One year later, Samantha is seen at Digal Corporation & working with her husband Nevel Rattan, distributing the Gaia Memories & becoming the Taboo Dopant to combat Kamen Rider Double Detective. Later when she kills Nevel & begins regularly visiting Dr. Mark Leitner to improve herself, she forms a partnership with him to overthrow her father & tries to kill Harmony Gardenar for not taking her side but the Smilodon Dopant drives her away. However, Leitner is defeated by Kamen Rider Accel Trial causing her coup to fail & she ends up on the lam. Samantha is hunted down by the Smilodon Dopant, who takes the Taboo Memory & leaves her for dead. She is then saved by Edric Barlow who offers his support in her scheme to take control of the Museum. After infiltrating the Digal Corporation, now with Harmony as its head, she obtains the Nasca Memory & then uses an L.C.O.G on herself instead of using the Memory with a Driver. Without inhibitions posed by a Driver, Samantha is able to use the Gaia Memory in its Level 3 state to become the R Nasca Dopant to overpower her sister. However, when Harmony evolves to ClayDoll Xtreme, which Samantha proves to be utterly powerless against, she is forced to go after other options to make herself more powerful, such as the Jewel Memory, before the Nasca Memory is destroyed in a confrontation with ClayDoll Xtreme. Later, after her father's death, Samantha is disillusioned until she learns of Harmony's survival & regains the Taboo Memory from Barlow after he announces that she has become the head of the Museum. However, no longer having a reason to prove herself with her father dead, Samantha fights Barlow in order to save her sister. As a result, the Taboo Dopant sacrifices herself to hold off the Utopia Dopant to give Harmony time to run away, resulting in Samantha's death as she finally admits the irony of her last moments in her final breath.

Dopant Forms
As a member of the Gardenar Family, Samantha owned a Gaia Driver & a golden Gaia Memory, the Taboo Memory to become the Taboo Dopant. But when they are taken from her by the Smilodon Dopant, she uses her ex-husband's Gaia Memory in place of them until it is destroyed. She then regained her original Taboo Memory from Barlow which she used against him, which lead to her death.

Taboo Dopant The Taboo Dopant is Samantha's first Dopant form accessed through the Gaia Driver & Taboo Memory. In this form she has the appearance of a rag doll & gains the ability to fly & generate deadly bombs of intensely hot light. It was further increased in power due to some modifications to her Gaia Driver by Leitner, to the extent of being unaffected by certain Dopant powers such as that of the Yesterday Dopant. This form is lost after Mick as the Smilodon Dopant takes her equipment away and nearly kills her. She regained the Taboo Memory after Barlow presented it to her, the memory was destroyed by the Utopia Dopant in a fight against him.

R Nasca Dopant The R Nasca Dopant is Samantha's second Dopant form, unlike her previous Dopant form she used the L.C.O.G on herself to create a Living Connector to use the memory instead of a Gaia Driver which limits the powers of the memory. Unlike Nevel's form which is blue with red markings, Samantha's is an orangish-red & possesses greater speed & power due to being Level 3. The R in the name stands for both Red (the forms color) & Revenge (Samantha's feeling towards her father & sister). But when Harmony evolves into ClayDoll Xtreme, Samantha went after other plans to empower herself further such as the Jewel Dopant. However, the Nasca Memory was destroyed in a fight against ClayDoll Xtreme.

History
Role of Healing Princess

Working as a DJ at Windy City's local Wind Wave 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, which was very popular among the citizens of Futo. Besides frequently broadcasting her hit single "Naturally", Wakana also announces rumors of happenings in Futo in her show. She also travels around Futo for her show, such as in episode 13 and 14 when she wanted to discover the best place for sweets in Futo. Her fans included Philip, Akiko Narumi, Shotaro Hidari (until he discovered her true personality), Mikio Jinno and Sachio Sawada, as well as numerous citizens of Futo. While she puts up a shy and kindly persona on the show, her true personality is the complete opposite. Her stint as the Healing Princess however, was not without problems. In episode 13, she assumed her ClayDoll Dopant form to kill a stalker Gaia Memory dealer who attempted to force her to marry him. The same episode and episode 14 featured her being the target of a stalker known as Mr. Question, later revealed to be her manager Tsuyoshi Ageo whom she had abused frequently. Wakana also had problems with another Wind Wave DJ, Motoko Saeki, who used Ageo to try to get rid of Wakana. Motoko found out about Wakana's identity as the ClayDoll Dopant, but was killed off by Kirihiko Sudo before she could expose Wakana on air.

In episode 13, Wakana is impressed and takes a liking to Philip. She is very honest with him and is delighted when she catches a glimpse of him appearing in the reality television show Fuuuuuutic Idol alongside Shotaro as the Kamen Singers in episode 23. In episode 24, Wakana also agrees to help Philip catch the Radio Tower Clown by claiming that she wishes to meet the Radio Tower Clown.

Weather Dopant
Dr. Mark Leitner was the 42-year-old head physician at the Leitner Medical Clinic. Ten years ago, finding no meaning in his life, he encountered Sebastian Gardenar attacking a group of people as the Terror Dopant. This brings maddening joy to the doctor & he made a point to get the Terror Memory for himself, experimenting on himself with numerous Gaia Memories with various Living Connectors on his body before Shroud gave him the Weather Memory in the hope that he would be powerful enough to eliminate Sebastian. As the Weather Dopant, he was armed with the whip-like Weather Mine & control over the weather: intense sunlight, heavy rain, lightning, tornadoes, & freezing snow.

He originally tested these abilities in a series of freezing, electrocution, & near-drownings which included Ace's family, to whom he was only known as the "man with the W Memory". Leitner does not use a Gaia Driver, as he feels he doesn't need the protection provided, as he was unaffected by their corruption due to him being already intensely psychotic, & the limits imposed on the power of Gaia Memories due to the Driver annoy him greatly. The Weather Dopant can also withstand Maximum Drives, as he has augmented the Weather Memory with other Gaia Memories' powers. This skill & his knowledge of Dopant physiology makes him an ally to the Museum, due to his experiments he burns a lot of calories & eats enough in one sitting for several people as a result. He modifies Harmony Gardenar's Gaia Driver to maximize her potential as the ClayDoll Dopant under Samantha's request.

After his identity was discovered during his failed attempt to add the Invisible Memory to his arsenal, Leitner takes refuge in the Gardenar estate where he convinces Samantha to take out her father so she can control the Museum & he can get the Terror Memory. Though he originally sees Samantha as merely one of his pawns & research material, he admits to having developed feelings for her. During his attempt to absorb the Quetzalcoatlus Memory, the Weather Dopant was finally defeated by Kamen Rider Accel Trial's Machine Gun Spike Maximum Drive, shattering the Weather Memory. Shortly afterwards, Leitner's excessive use of Gaia Memories causes his body to become covered in Living Connectors that dissolve him away into nothingness as he tells the Kamen Riders that Shroud will be their end.

Shroud later expressed regret to Ace for giving Leitner the Weather Memory, having no idea of what a monster he would become with the Memory.

Leitner does not use a Gaia Driver, as he feels it only limits the power of Gaia Memories, & he is unaffected by their corruption as he was already intensely psychotic. The Weather Dopant can also withstand Maximum Drives, as he has augmented the Weather Memory with other Gaia Memories' powers. This skill & his knowledge of Dopant physiology makes him an invaluable ally to the Museum.
