This Shocker Combatman (ショッカー戦闘員,Shokkā Sentōin) was a character who changed bodies with Ikki Igarashi when he and his siblings lost to the Kamen Rider impression punishment game. This allowed him to temporarily become Kamen Rider Revi (仮面ライダーリバイ,Kamen Raidā Ribai) himself.
Rex Genome (レックスゲノム,Rekkusu Genomu) is Revi's Tyrannosaurus rex-based primary form accessed by using the Rex Vistamp in the Revice Driver.
Compared to Vice, Revi has higher punching and kicking power but lower jump height and running speed. In this form, Revi can transform his legs into those resembling the T-Rex, which grants him high jumping power and powerful kicks.
Rex Genome consists of the following parts:
Rex Revi Head (レックスリバイヘッド,Rekkusu Ribai Heddo): The head.
Rex Revi Top (レックスリバイトップ,Rekkusu Ribai Toppu): The head armor. The strong armor made of the rare metal Astmetalum (アストメタルム,Asutometarumu) is shaped like an egg to efficiently release impacts and protect the head.
Rex Revi Eye (レックスリバイアイ,Rekkusu Ribai Ai): The compound eyes. With the dynamic vision and wide viewing angle of the carnivorous dinosaur, which can be said to be the eyes of a hunter, it is possible to accurately capture the movement of any small target.
Revice Signal (リバイスシグナル,Ribaisu Shigunaru): The Genome regulator. It has the role of improving the accuracy of cooperation by adjusting the output and timing with Kamen Rider Vice, who becomes a buddy.
Rex Revi Crusher (レックスリバイクラッシャー,Rekkusu Ribai Kurasshā): The oral cavity. It has excellent respiratory efficiency and can take in the same amount of oxygen as normal even under low oxygen.
Rex Embreast (レックスエンブレスト,Rekkusu Enburesuto): The chest armor. The unique ability engraved with the symbol mark makes the user a T-Rex warrior. In addition, the R-factor incorporated into the Revice stamp was developed exclusively for the Revice system and is based on the Revice Genome, which has the best output balance.
Revi Genomic Suit (リバイゲノミックスーツ,Ribai Genomikku Sūtsu): The reinforced suit. Deployed at the same time as the Buddy Up, the genetic information of the species supplied from the Revice Driver is reconstructed, and by wearing it in an enhanced shape, the user is transformed into Kamen Rider Revi.
Rex Revi Shoulder (レックスリバイショルダー,Rekkusu Ribai Shorudā): The shoulders. This powerful armor that reproduces the tough body surface that repels everything is mainly made of the rare metal Astmetalum (アストメタルム,Asutometarumu) that is collected from meteorites, and the Genomic Suit transforms the genetic information of the species into a more competent shape.
Rex Revi Arm (レックスリバイアーム,Rekkusu Ribai Āmu): The arms. The energy supplied from the Revi Genomic Suit enhances the physical ability of the user, and they are strengthened by adding the toughness of the T-Rex.
Rex Revi Glove (レックスリバイグローブ,Rekkusu Ribai Gurōbu): The gloves. The strength of T-Rex's strong jaw is reflected in the grip strength, and it exerts the power to crush a large tree.
Rex Revi Leg (レックスリバイレッグ,Rekkusu Ribai Reggu): The legs. By partially swinging the Genome Shift (ゲノムシフト,Genomu Shifuto) that controls the composition balance of the Revi Genomic Suit toward the species side, the shape becomes very similar to the legs of the T-Rex, creating overwhelming destructive power.
Rex Revi Boots (レックスリバイブーツ,Rekkusu Ribai Būtsu): The boots. The structure named arctometatarsal possessed by dinosaurs specializing in running has been reproduced, dramatically improving running power. In addition, by receiving the operation of the Revice Driver and gathering high-density energy on the sole of the foot, the finishing move Rex Stamping Finish can be activated. This makes it possible to cancel the contract of a Deadman.
