Daigo Tachikawa (立川 大吾, Tachikawa Daigo) was a Native Worm that appeared in Kamen Rider Kabuto.
History[]
He was first seen asking Tendo to stop collecting the Zecters as it will put his and Hiyori's lives in danger. Tendo took it as a threat and prepared to transform, only for the Kabuto Zecter to calmly land on Daigo's palm. Because of his natural peaceful nature, he often tries his best to escape the Invader Worms, he uses his power only to defend the ones around him. He works at a nursery school and loves playing with the kids. After class one day, Daigo Tachikawa was nearly attacked by a Worm, but Kagami saves him. Daigo was given a chance to run away, but saw a mother and her child being threatened by Worms. So Daigo changed to his Native form and attacked the other Worms, letting the mother and child escape.
Having the ability to summon any Zecter, he summons the Drake Zecter with the Grip attached and transformed into Drake, destroying all the Pupa Worms and driving Cochlea Worm away. He was wounded and Kagami took him to Tsurugi's house. Tachikawa discovered Tsurugi's true form as Scorpio Worm after shaking hands with him and Tsurugi discovered like-wise. Using the Discalibur, Tsurugi begins to attack Tachikawa, saying he is a Worm and must be destroyed. Tachikawa counters by calling the Sasword Zecter with Yaiver swinging towards him, smashing the Discalibur, and escaped using the Clock Up feature. After Riku Kagami told both Tendo and Arata that both Kabuto and Gatack Zecter are created to endlessly fighting Worm, Daigo was nearly killed after Kabuto was out of control due to Red-Shoes system. But this isn't the main reason he died afterwards as Daigo was killed by a Cochlea Worm. His death had been avenged by Tendo when he transforms into Kabuto Hyper Form and finishes the Worm with Hyper Kick.
