"My soul is with the ZECT!"
―Yamato's last words.[src]

Tetsuki Yamato (大和 鉄騎 Yamato Tetsuki) was one of three Kabutech Riders of Kamen Rider Kabuto: God Speed Love.

With Ketaros Zecter, he was able to transform into Kamen Rider Ketaros (仮面ライダーケタロス Kamen Raidā Ketarosu, Masked Rider Ketaros).


Kamen Rider Kabuto: God Speed Love

A prominent and loyal member of ZECT, he is the user of the Ketaros Zecter. Yamato knows that anyone who has betrayed ZECT must be destroyed and is the given the mission to eliminate Neo-ZECT and follows Mishima's orders to create the Jacob's Ladder station. During the chase of Zect on Neo Zect organization, Arata came in the middle of the clash before the fighting started and told the groups to call the fight off so they won't harm each other and only focused on defeating Worm. Tetsuki Yamato, the leader of the Zect troops accepted Arata's favor and kneeled on Hidenari Oda, the leader of Neo Zect to have him and the rests of the Neo Zect to come back to Zect. Unfortunately, Hidenari stepped on Tetsuki and called him and the rests of the Zect members to be the pathetic dog and Hidenari Oda won't let himself alongside the rests of his groups to be like Zect. This lead to have Arata to be caught in the fight of Zect and Neo Zect with Tetsuki transformed into Ketaros and Hidenari transformed into Hercus. Daisuke Kazama also joined Neo Zect and transformed into Drake with Arata transformed into Gattack. The fight wasn't taking a long time as Souji Tendou/God Speed Love appeared and showed his strength as Kamen Rider Kabuto, beating both sides in ease and offered them his strength with a note that it would be expensive.

He later fights Kabuto at the station and they fight in outer space using Clock Up. After finding out that Kabuto's intention is to meet Kamen Rider Caucasus during their fight, they later fall off the station with Kabuto being saved by the Kabuto Extender while Ketaros dies, gloriously shouting "My soul is with the ZECT!" upon re-entering Earth's atmosphere, even though Kabuto's offer to save him was rejected.
