Poseidon is a Greeed-like entity who posesses Michal Minato and becomes Kamen Rider Poseidon, and is the main antagonist who appeared in the OOO section of the Movie War Mega Max film.
Poseidon is a Greeed-like entity formed from the Cell Medals and Core Medals within Michal's body, turning him evil 40 years into the future. As Michal, he is given three Core Medals and the Poseidon Driver which he receives from the remnants of the Kougami Foundation in his time. He then becomes able to transform into Kamen Rider Poseidon. He then arrives to the present time in Michal's body to eliminate all Kamen Riders. The Kamen Rider Poseidon entity is eventually split from Michal's body in his Kamen Rider Poseidon form.
Kamen Rider Poseidon was defeated by Kamen Rider OOO Tajadol Combo's Providence Drop and Kamen Rider Aqua's Oceanic Break, with his Core Medals taken for Kannagi to transform into the Super Galaxy King.

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, who is actually a 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 Galaxy King. After Super Galaxy King's destruction, Poseidon's Core Medals fells into the Earth.
Just like OOO, the Poseidon Driver also utilizes Core Medals and is somewhat simpler-looking, shaped in a circle with outer design. Unlike the way OOO arranges his Core Medals to transform, Poseidon had his Core Medals put in an inverse triangular position on the Driver rather than being straight and diagonal, like OOO's. It does not require a scanner like OOO does.
Deepest Harpoon is an large crimson harpoon which serves as Poseidon's primary weapon.
Just like OOO, Poseidon uses three marine life Core Medals. But unlike OOO's Core Medals, these three Core Medals that Poseidon have are created by Kougami Foundation by Kosei Kougami, as well as the fact that one of the Cores does not have the same color as the other two. These three Core Medals does not belong to any of the Greeed, and it is only used to utilize the Poseidon Driver to transform into Kamen Rider Poseidon. Head:
- Same Medal:The light blue Shark Medal, enabling Poseidon to use the Same Head.
- Kujira Medal:The dark blue Whale Medal, enabling Poseidon to use Kujira Arms, it also gives Poseidon a whale shoulder design.
- Ookamiuo Medal:The dark red Wolf fish Medal, enabling Poseidon to use Ookamiuo Legs.
