Kamen Rider Poseidon

"Same, Kujira, Ookamiuo!"
―Transformation announcement[src]
  • Height: 204cm[1]
  • Weight: 89kg[1][2]
  • Punching Power: 3.5 t.[1]
  • Kicking Power: 7 t.[1]
  • Maximum Jump Height: 45 m.[1]
  • Maximum Running Speed: 100 m. per 6.1 sec.[1]

Similar to OOO, possessed Michal puts three Core Medals on the Poseidon Driver, and transform into the evil Kamen Rider Poseidon. The chest design have an inverse triangular position, which are arranged in the order of the Same on the right, Kujira on the left, and Ookamiuo below the Same and Kujira, unlike OOO's straight and diagonal arrangement. Kamen Rider Poseidon is designed as the light blue Same Head, the dark blue Kujira Arms with a whale's head on right shoulder and whale's tail on the left shoulder, and the dark red Ookamiuo's legs. Kamen Rider Poseidon uses a crimson spear as weapon.

Kamen Rider Poseidon consists of the following parts:

  • Poseidon Mask (Shark Head) (ポセイドンマスク(シャークヘッド) Poseidon Masuku (Shāku Heddo)): The helmet.
  • Triangle Delta (トライングデルタ Toraingu Deruta): The symbol of Poseidon is embodied as a plate. It also functions as armor to protect the chest.
  • Whale Chest (ホエールチェスター Hoēru Chesutā): A large thoracic exoskeleton that protects Poseidon's chest. Largely developed exoskeletons overlap to form thick armor, protecting Poseidon's upper body from all attacks.
  • Whale Shoulders (ホエールショルダー Hoēru Shorudā): Poseidon's shoulder exoskeleton. They protect Poseidon's shoulders along with the Whale Chest. It has both robustness and flexibility so that it does not restrict the movement of the shoulder when swinging the long spear "Deepest Harpoon".
  • Whale Gantrex (ホエールガントレクス Hoēru Gantorekusu): An exoskeleton that protects Poseidon's forearm. The streamlined line drive makes it possible to minimize water resistance when swimming at the speed of light in water.
  • Whale Gloves (ホエールグラバー Hoēru Gurabā): Reinforced exoskeleton-like skin that wraps the five fingers. It has powerful power and is said to tear the armor of a 20 cm thick battleship.
  • Whale Guardias (ホエールガーディア Hoēru Gādia): An exoskeleton that protects the back of Poseidon's hand. The line drive that covers the surface amplifies the power sent from the core medal and improves the punching power.
  • Wolffish Finch (ウルフィッシュフィンチ Urufisshu Finchi): A reinforced exoskeleton that covers Poseidon's thighs. Although it is large, it is thin and lightweight, so it does not interfere with the movement of the lower body, and its defense power is greatly improved. In addition, when water passes through the line drive that covers the surface of the exoskeleton in water, it is discharged like a jet jet to convert it into a rearward propulsive force.
  • Wolffish Knee Dias (ウルフィッシュニーディアス Urufisshu Nī Diasu): An exoskeleton that covers Poseidon's knees and shins. The knees' fin blade has a sharp tip that suppresses shape resistance to the utmost limit and has the function of increasing the speed and power of kicking in water.
  • Wolffish Ankle Toes (ウルフィッシュニーディアス Urufisshu Ankuru To~u): An exoskeleton that protects Poseidon's ankles. It is composed of extremely flexible reinforced muscles inside, and can swim in the water with the same movement as the tail fin of fish.
  • Wolffish Soles (ウルフィッシュソール Urufisshu Sōru): An exoskeleton that covers Poseidon's feet. The sole fin blade located in the central part has the function of assisting a sudden change of direction in water and increasing mobility.

Kamen Rider Poseidon, is actually the Greeed inside Michal's body. The Greeed overtook Michal's body and arrived to the present. It has the ability to create Waste Yummy, like how Uva did. The Greeed split from Michal, after losing some Core Medals to Eiji and Ankh. He was able to form his own body by using Core Medals and Cell Medals, in the form of Kamen Rider Poseidon. Then, Poseidon has been defeated at the hands of Kamen Rider OOO Tajadol Combo's Providence Drop and Kamen Rider Aqua's Oceanic Break. However, Kamen Rider Poseidon's Core Medals are taken for Kannagi to transform into the Super GingaOh. After Super GingaOh's destruction, Poseidon's Core Medals fells into the Earth and as the location of the medals were unknown.
