As the Fang Memory was designed for Philip, his and Shotaro's roles as Double are reversed in FangJoker, with Shotaro's consciousness transferred into Philip's body for the transformation, Double's left eye flashes whenever Shotaro speaks. This form is described as the {{nihongo|Wild Skilled Warrior|野生技戦士|Yasei Waza Senshi}}, as the transformation takes an extreme tax on Philip's body as he tends to lose control of himself when in this form during its first two uses.

It is also known as the {{nihongo|Evolved Perfect Warrior|進化完璧戦士|Shinka Kanpeki Senshi}}, as it also represents the perfect union between Shotaro and Philip. The sheer knowledge of this form wields allows Double to instantly analyze the opponent's capabilities. While not as physically strong as FangJoker, this Form seems to have better defenses as it easily withstood the Weather Dopant`s attacks without using the Prism Bicker.
 * Height: 195 cm
 * Weight: 82 kg
 * Punching Power: 5 t.
 * Kicking Power: 10 t.
 * Double Xtreme: 80 t.
 * Maximum Jump Height: 120 m.

During the transformation, the middle of Double begins to glow as the Xtreme Memory absorbs the Cyclone and Joker Memories and attaches itself onto the Double Driver. The Xtreme Memory opens up revealing a spinning X as Double rips open the center revealing the prism-colored center.

Unlike the other forms of Double, where Shotaro or Philip provide the body for their Rider Form, the Xtreme Memory absorbs Philip's body and fuses it with Shotaro's body in their Rider Form becoming one in body, mind and soul. Thus when either Philip or Shotaro speaks on their own, their respective side's eye flashes, and why they also appear together as soon as they break the transformation.

By gathering energy into his fists from either halves Double can throw powerful punches at the opponent.

In this form, Double wields the Prism Bicker which has its own Maximum Drives. Unlike the other forms of Double, CycloneJokerXtreme's motif also includes the letter X.

 * Prism Sword finisher:
 * {{nihongo|Prism Break|プリズムブレイク|Purizumu Bureiku}}: After inserting the Prism Memory into the Prism Sword and by pressing the Maximum Starter button on its hilt, Double can perform an energized slash or a wave of energy.
 * Prism Bicker finishers:
 * Through the Prism Memory's ability to link Philip's three elemental Gaia Memories with the Joker Memory, the Prism Bicker allows CycloneJokerXtreme to perform two quadruple power Maximum Drives:
 * {{nihongo|Bicker Charge Break|ビッカーチャージブレイク|Bikkā Chāji Bureiku}}: A powerful version of Prism Break. Double combines the power of the Prism Sword and the 4 Gaia Memories and delivers an enhanced version of the Prism Break slash. A variation of the Bicker Charge Break turns the Bicker Shield into a whirling disc of energy which Kamen Rider Double can ride like a surfboard, allowing him to perform the Maximum Drive against an airborne foe.
 * {{nihongo|Bicker Finallusion|ビッカーファイナリュージョン|Bikkā Fainaryūjon}}: Double combines the power of the Prism Bicker and the 4 Gaia Memories and delivers a powerful laser blast. A variation of Bicker Finallusion in which the Metal Memory is used in place of the Joker Memory creates a strong energy shield capable of withstanding a wide-area devastation attack from Claydoll Xtreme.

CycloneJokerXtreme's ending theme is entitled "Extreme Dream".

Shroud states that Ryu's hatred and rage is needed for Double to fight at its full potential. However this form was never utilized in the series as Ryu decides not to fight as part of this form while showing Shroud that they can fight with compassion rather than hatred. {{-}} {{!}}-{{!}} CycloneJokerGoldXtreme=  CycloneJokerGoldXtreme 1={{-}} 2={{-}} 3={{-}} {{nihongo|CycloneJokerGoldXtreme|サイクロンジョーカーゴールドエクストリーム|Saikuron Jōkā Gōrudo Ekusutorīmu}} is the second evolved form of CycloneJokerXtreme. This form is achieved when intense wind blows against Double and into the Xtreme Memory, and activates its full potential.

In this form, the Crystal Server turns golden, with a set of insect wings that flurishes out of Double's back, allowing Double to fly. Double uses this form again in Movie War Core to finish off Kamen Rider Core with Kamen Rider OOO Tajadol Combo.

This form's Memory Break finisher is the {{nihongo|Golden Xtreme|ゴールデンエクストリーム|Gōruden Ekusutorīmu}}: Double performs a flying, golden version of the Double Xtreme kick.

CycloneCyclone gains the power of wind while JokerJoker gains the power of agility and strength.

When Decade uses the Final Attack Ride Card, CycloneCyclone, JokerJoker, and Decade perform the three-way {{nihongo|Triple Extreme|トリプルエクストリーム|Toripuru Ekusutorīmu}} attack, where both Doubles use their traditional Drop Kicks while Decade uses his traditional Flying Side Kick.

It wields the power of all 20 Heisei Kamen Riders. In this form, Zi-O is adorned with statues of all the previous Heisei Riders, with his own on his crown.
 * Rider Height: 208.5 cm
 * Rider Weight: 120.0 kg
 * Punching Power: 55.8 t
 * Kicking Power: 129.2 t
 * Maximum Jump Height: 146.6 m
 * Maximum Running Speed: 100 m per 0.4 sec.

GrandZi-O is unique to the modern Sougo and is exceedingly superior to his other Zi-O forms. When compared to the ability parameters of other forms, GrandZi-O surpasses all others in every category by a considerable margin. Aside from its impressive parameters, GrandZi-O can use the Rider Relief statues around its armor to activate various abilities related to the main Kamen Riders of the Heisei Era. When GrandZi-O taps a Rider Relief once, he can create a time portal that summons a specific Rider from their timeline. However, GrandZi-O cannot summon Decade with the NeoDecadriver. When GrandZi-O taps a Rider Relief twice, he can summon any weapon from that Rider's arsenal. The Zi-O Rider Relief appears to be activated by head gesture and, when activated, suspends or releases all summoned Riders in temporal stasis, regardless of their position.

GrandZi-O is directly powered by the 19 Heisei Ridewatches in his collection. As a result, any anomalies regarding the Ridewatches, such as the temporal paradox caused by possessing the Drive Ridewatch that originated from Ohma Zi-O's timeline, will drastically compromise GrandZi-O's control over the corresponding Rider's power. This affects GrandZi-O's ability to summon the Rider, as shown during his summoning of Drive during his second encounter with Ohma Zi-O, who quickly seized control of the summoned Rider. Eventually, Sougo would acquire his own Drive Ridewatch from Krim Steinbelt, enabling GrandZi-O to correct temporal anomalies and paradoxes.

Other issues afflicting this form include GrandZi-O's inability to command and control Dai Mazines and having its power restricted to the powers of the Main Heisei Riders. These factors make GrandZi-O inferior to Ohma Zi-O in overall ability.

Should any of the Ridewatches become unusable, it will immediately cancel out GrandZi-O's transformation and the Ridewatch will disappear.

GrandZi-O consists of the following parts:
 * {{Nihongo|Grand Caliber A|グランドキャリバーA|Gurando Kyaribā A}} - The helmet. 'A' stands for 'Analog'.

Compared to other Riders in the series, Ohma Zi-O possesses the highest stats. While Ohma Zi-O's stats are somewhat balanced, he has a tremendous kicking power, which is higher than most of Kamen Riders. He also has high punching and jumping powers, though they're still lower than that of many Legend Riders. However, it should be noted that since he has full control over Legend Rider Powers, he can manipulate his stats using those powers if needed. The only form of Zi-O stronger than it is OhmaForm, but possibly only in terms of physical stats.

This form wields the powers of every single Kamen Rider in existence and can command the Dai Mazines. According to the original Ohma Zi-O, this form possesses the power to not only destroy time and space itself, but to recreate everything into whatever the user wishes.
