Ryu Terui

Kamen Rider Accel (仮面ライダーアクセル Kamen Raidā Akuseru) is a fictional character in the 2009 – 2010 Kamen Rider Series, Kamen Rider Double, and is the series second Kamen Rider after the titlular Kamen Rider Double. The name comes from the English word "acceleration" and his motif is that of the letter A as well as a motorcycle.

Ryu Terui
Ryu Terui (照井 竜, Terui Ryū, portrayed by Minehiro Kinomoto) is a Superintendent appointed to the Futo Police Department's Paranormal Crime Investigation Division (超常犯罪捜査課, Chōjō Hanzai Sōsaka), and is Jinno and Makura's superior. Prior, Ryu lost his family when they were murdered by Isaka, driving Ryu to find the "Man with W Memory" with the aid of the mysterious Shroud while developing a hated of Futo and seeing it as a gathering place of all kinds of scum.

Though he and Shotaro Hidari clash at first, Ryu becomes an ally to the Narumi Detective Agency when it comes to investigating the Dopant crime wave, as well as picking up some of Shotaro's habits in dealing with Dopants even after losing it upon finally finding his family's killer: the Weather Dopant, Shinkuro Isaka. After obtaining the Trial Memory from Shroud and learning to use it, Ryu is able to finally take his revenge on the Weather Dopant, using the Trial Maximum Drive to destroy his Gaia Memory, after which Isaka dissolved as a result of his long term abuse of Gaia Memories. After Isaka's death, Ryu becomes more open to the others and continues his role as a Kamen Rider to fight off the Dopant crime wave prior to learning that it was Shroud who gave Isaka the Weather Memory, though she had no idea that his family would suffer as a result. Furthermore, Ryu learns he has a unique physiology, enabling him to withstand the intense power of certain Gaia Memories and was selected by Shroud because he can resist the Terror Dopant's Terror Field.

In his Rider form, Ryu tends to say "Now, let's break away!" (さあ、振り切るぜ!, Saa, furikiru ze!) whenever he assumes his Rider forms and states "Despair awaits you (all) at the finish!" (絶望がお前（たち）のゴールだ!, Zetsubō ga omae (-tachi) no gōru da!, as Accel) and ""[0.1-9.9] seconds, that is the time left until your despair!" (○○秒、それがお前の絶望までのタイムだ！, [0.1-9.9]-byō, sore ga omae no zetsubō made no taimu' da!, as Accel Trial) upon executing a Maximum Drive attack. The words on the back of his jacket read "[A] Spiritual state of nothingness makes even fire itself cool".

Ryu Terui makes a cameo appearance at the end of Kamen Rider × Kamen Rider Double &amp; Decade: Movie War 2010 proclaiming that Kamen Rider Double is not the only Kamen Rider in Futo City any more.

Statistics
Ability Perimeters: Like Kamen Rider Double, Ryu Terui transforms into Kamen Rider Accel through the use of USB flash drive-like objects called Gaia Memories. However, Accel only has access to a single form with which he fights through the use of the Accel Memory which he inserts into the AccelDriver. His Maximum Drive is the Rider Kick Accel Glanzer, after charging up to a point when Accel is engulfed in orange flames he executes a jumping spinning heel kick. This can be used with Kamen Rider Double FangJoker's Fang Strider to perform the Rider Twin Maximum finisher. While armed with the Engine Blade, Kamen Rider Accel has additional Maximum Drives.

Bike Form
The power of the Accel Memory allows Accel to change into a motorcycle-like form called Bike Form. This form is accessed by removing the AccelDriver buckle from the belt when the Face Flasher (フェイスフラッシャー, Feisu Furasshā) lights up. Bike form can also combine with Double's Boilder, Turbler, and Splasher units to become the AccelBoilder (Start Dash mode too), AccelTurbler, and AccelSplasher. In Kamen Rider Double Forever: A to Z/The Gaia Memories of Fate, Bike Form has its own Maximum Drive after the Engine Memory is inserted in the Accel Driver and Accel switches to Bike Form. The Maximum Drive is a super-powered dash as Bike Form through the target and it is called the Bike Engine Dasher

Accel Trial is the powered up form of Kamen Rider Accel. It is much faster than Accel's normal form, but its armor and overall power is weaker as a result. It makes up for its weakness by being able to punch and kick much faster, as well as increasing his overall movement speed (running, dodging, etc.) to a great degree. Once the Maximum Drive is initiated, Accel Trial can only be used for another 10 seconds before being forcibly reverted back to human form, but the transformation is retained if the Trial Maximum Drive is successful before the 10 seconds are up. This form's Maximum Drive is the Machine Gun Spike (マシンガンスパイク, Mashingan Supaiku) Rider Kick, a series of of multiple kicks in a row which leave a series of energy treadmarks in the form of a T, only limited by the amount of kicks Accel uses before time runs out.

While transforming from into Accel Trial, Kamen Rider Accel changes colors from red, to yellow, and then finally to blue as Accel Trial. The yellow colored form has been labeled as Kamen Rider Accel Yellow Signal Version (仮面ライダーアクセルイエローシグナルバージョン, Kamen Raidā Akuseru Ierō Shigunaru Bājon?) in the toy line.

Accel Driver
The Accel Driver (アクセルドライバー�Akuseru Doraibā) is Kamen Rider Accel's transformation belt. It is a third generation Memory Driver given to Ryu Terui by the mysterious woman known only as "Shroud". The AccelDriver resembles a set of motorcycle handlebars. By inserting the Accel Memory into the Mono Slot (モノスロット Mono Surotto) and revving the Power Throttle (パワースロットル Pawā Surottoru) on the right handlebar, Ryu Terui transforms into Kamen Rider Accel. By squeezing the Maximum Clutch Lever (マキシマムクラッチレバーMakishimamu Kuratchi Rebā) on the left handlebar and revving the Power Throttle, Kamen Rider Accel initiates his Maximum Drive (マキシマムドライブ Makishimamu Doraibu) finisher attack.

Gaia Memories
Like Kamen Rider Double, Kamen Rider Accel possesses his own set of Gaia Memories (ガイアメモリ Gaia Memori).
 * Accel Memory (アクセルメモリ Akuseru Memori): The Accel Memory, or Acceleration Memory (加速の記憶�Kasoku no Kioku), is Kamen Rider Accel's primary GaiaMemory. This enables Terui to transform into Kamen Rider Accel and access his primary Maximum Drive, as well as allow him to assume Bike Form.
 * Engine Memory (エンジンメモリ Enjin Memori): The Engine Memory is a Gaia Memory that gives the EngineBlade its various different powers. It is not a true Gaia Memory however, and its powers are linked to the Accel Memory. This allows the Engine Blade to have three different elemental abilities imbued in it, each based on a different type of engine: Jet (ジェット Jetto) which allows the Engine Blade to fire jet blades or a blade energy wave, Electric (エレクトリック Erekutorikku) which allows the Engine Blade to do high powered electric slash, and Steam (スチーム Suchīmu) which creates a wave or wall of steam.
 * Cyclone Memory (サイクロンメモリ, Saikuron Memori): Ryu is briefly lent Philip's Cyclone Memory to battle the Weather Dopant. When inserted into the Engine Blade, it allows Kamen Rider Accel to perform a wind-powered Maximum Drive.

Trial Memory
The Maximum Counter Trial Memory (マキシマムカウンタートライアルメモリ, Makishimamu Kauntā Toraiaru Memori), also known as the Challenge Memory (挑戦の記憶, Chōsen no Kioku), is a special Gaia Memory that allows Kamen Rider Accel to become Kamen Rider Accel Trial. While in Memory Mode (メモリモード, Memori Mōdo), the Trial Memory enables Accel to transform; the transformation is complete once the light on the traffic light-like Trans-Signal (トランスシグナル, Toransu Shigunaru) goes from red to blue (with a 3-second countdown sound effect). While in its stop watch-like Maximum Mode (マキシマムモード, Makishimamu Mōdo), once the Maximum Switch (マキシマムスイッチ, Makishimamu Suitchi?) timer button is pressed, Accel Trial has 10 seconds to perform as many kicks as possible before pressing the Maximum Switch again to activate the Maximum Drive. If the Maximum Switch is not pressed within 10 seconds, the Maximum Drive fails and Accel's transformation is forcibly and painfully reverted. To handle this, Accel normally tosses the Trial Memory into the air as the Maximum Drive begins, pressing the Maximum Switch as soon as it is caught and declaring the time received.

Engine Blade
The Engine Blade (エンジンブレード Enjin Burēdo) is Kamen Rider Accel's main weapon. The weapon can be wielded outside of Accel's transformation, though it is extremely heavy. Through the use of the Engine Memory, Kamen Rider Accel can perform different elemental powers by pulling the trigger. It also allows Accel to perform two unique Maximum Drive finishers with the Engine Blade. The first is the Dynamic Ace (ダイナミックエース, Dainamikku Ēsu) in which a concentration of energy in the shape of the letter A is sent out from the EngineBlade. The second is called the A-Slasher (エースラッシャー, Ē Surasshā) where Kamen Rider Accel performs three consecutive slashes that form the letter A in a horizontal or vertical plane, slashing through the Dopant to destroy it. The Engine Blade can be used with any of Double's Memories for a Maximum Drive. As Kamen Accel Trial, he is able to perform a variation of his Machine Gun Spike Maximum Drive by using the Trial Memory in combination with the Engine Blade's Maximum Drive. When Accel Trial combines the Engine Maximum Drive with the Trial Maximum Drive, he can perform the Machine Gun Slasher (マシンガンスラッシャー, Mashingan Surasshā) Maximum Drive, repeatedly slashing the target in the time limit rather than kicking.

Memory Gadget
Like Double, Kamen Rider Accel has his own Memory Gadget (メモリガジェット Memori Gajetto), an item powered by an artificial Gaia Memory called a Giji Memory (ギジメモリ Giji Memori, "Pseudo Memory") that allows it to switch between its Gadget Mode (ガジェットモード Gajetto Mōdo) and its Live Mode (ライブモード Raibu Mōdo).
 * The Beetle Phone (ビートルフォン�Bītoru Fon) is a mobile phone that switches between Cell Phone Mode (携帯モード Keitai Mōdo) and Beetle Mode (ビートルモード Bītoru Mōdo) with the use of the Beetle Memory (ビートルメモリ Bītoru Memori). It looks similar to the Stag Phone, except it has a blue Japanese rhinoceros beetle design. Prior to its appearance in the series, Ryu Terui used the Beetle Phone to spy on the Narumi Detective Agency.

Diablossa
The Diablossa (ディアブロッサ, Diaburossa) is Kamen Rider Accel's personal Ducati 999 motorcycle. It also has a holder for the EngineBlade. Its name comes from the Italian words "Diablo" and "Rosso" fitting as Ducati is an Italian company.[6]

Gunner A
The Revol-Interchange Gunner A (リボル換装 ガンナーA, Riboru Kansō Gannā Ē) is a robotic tank that serves as Kamen Rider Accel's support droid. Its AI allows it to operate on its own from Accel. The technology is similar to Kamen Rider Double's HardBoilder and the front unit can also combine with the Gunner A to become the HardGunner (ハードガンナー, HādoGannā).

Accel Gunner
Accel Bike Form can combine with to become the AccelGunner (アクセルガンナー, Akuseru Gannā). The Accel Memory links with the Gaia Cannon (ガイアキャノン, Gaia Kyanon) to release energy similar to a Maximum Drive called the Gunner Full Break (ガンナーフルブレイク, Gannā Furu Bureiku). It is also armed with the Gattling Wheel (ガトリングホイール, Gatoringu Hoīru), Bike Form's back wheel turned into a machine gun.

Accel Turbuler
Accel Bike Form, in battle against Ryubee Sonozaki's Terror Dragon, combined with the RevolGarry's Turbuler unit to form and fight as the '''AccelTurbuler. '''
