Kamen Rider Ryuki Special: 13 Riders
Takamizawa was one of the people whom Kanzaki offered to join the Rider War. Takamizawa accepted, seeking to gain the power to rule the world and thus, Takamizawa became Kamen Rider Verde.
In the special, Verde was the one who killed Kamen Rider Raia. He later saw Shinji as a threat and went after him, teaming up with several other "evil" Riders to defeat him. In a fight with Kamen Rider Knight, Verde mortally wounded the Rider with his Final Vent, only to be killed by Knight's Final Vent right after.
