|This article is about a/an rider form used by several identities in the Kamen Rider Series.|
Kamen Rider Amazon Sigma may refer to any the following characters.
Amazon Origin (アマゾン素体 Amazon Mototai) is Amazon Sigma's initial form before equipping the Amazons Driver. In his case, it appears to be identical to his default form.
- "Sigma! (Mixture electric music)"
- ―Transformation announcement[src]
By using the specialized Amazons Driver made by Tachibana and his crew, it allows Jun to transform into Amazon Sigma.
Thanks to the newly developed Amazon Cells that are implanted in his body, he doesn't need to eat to restore his energy to transform again. Also, the belt allows him the ability to not feel pain, which acts both as an advantage and an disadvantage, as shown during his debut and his death.
- Sigma Header (シグマヘッダー Shiguma Heddā): Sensor Antenna. Able to detect noise and enemy presence in his surroundings.
- Amazon Eye (アマゾン・アイ Amazon Ai): Able to change focus at will and catch a target 1k meter away even if they are at high speed.
- Crusher (クラッシャー Kurasshā): Sigma's fang. Sharp fangs which can easily chew through steel.
- Converter Lung (コンバーターラング Konbātā Rangu): Sigma's chest. With the Amazons Driver's influence, the Amazon cells harden themselves to protect the core inside by cancelling almost all damage. It can also absorb heat and wind from the surrounding and convert it to stock energy.
- Shell Break Arm (シェルブレークアーム Sheru Burēku Āmu)：Arm cutter that can give the enemy severe damage to the internal hub.
- Shell Break Leg (シェルブレークレッグ Sheru Burēku Reggu)： Boot cutter that can momentarily activate the cell and enhanced motor function.
- Knee Hex (ニーヘクス Nī Hecusu): Knee protector that can observe the quake and strengthen the knee.
- Wilder Crust (ワイルダークラスト Wairudā Kurasuto)：A skin that can moderately fasten and stretch the joints and muscles, also can change the hardness of parts of the body to defend from an enemy's attack.
