Drake Holme

Drake Holme is the aide of ZECT HQ's leader, Aaron Williams. He is also one of TheBee Zecter users. Later he was revealed as one of true main antagonists of the series and used the form of Gryllus Worm (グリラスワーム) in episode 48 of Kamen Rider Kabuto.

At times he does communicate with Trip Lister and Shuichi Tadokoro to brief the ZECT teams about the Worms. Eventually, he was upset with Yaguruma botching a mission and Tadokoro questioning him about ZECT's agenda. There's implication that he has no faith in Lister as Hornix, despite Lister being loyal to ZECT and is looked down upon by Kamishiro. He has no sense of taste, and finishes eating by taking a supplement. He forcefully became Hornix at one time despite the Hornix Zecter's attempt to reject him. He truly thinks Kageyama is an eyesore because he can only complain and has lost the Hornix Zecter. He also seems to have a connection to Rena Mamiya/Uca Worm and had always kept the Hyper Zecter with him. Renge manages to steal the case with the Hyper Zecter, but Uca Worm takes it back only to find that the case has been rigged with a bomb.

Mishima tries to destroy the Hyper Zecter with the bomb. After the explosion, he taunts Tendou for failing to obtain the Hyper Zecter. However, he doesn't realize the power of the Zecter as it manages to finds its way to Tendou, much to his chagrin. He then tosses his glasses to the ground in anger. He gradually loses respect for Riku Kagami's servile manner toward the Natives. After realizing Ned found out about the Red-Shoes system, he makes a pact with Ned and overthrows Aaron Williams as leader of ZECT. Using the Natives' pendants, he gains the ability to turn into Gryllus Worm, the strongest Native. He is defeated by Hyper Beetleborg's and Boron's Rider Kick and then destroyed by the meteorite explosion that obliterated the studio set.

The form Drake took on after using multiple necklaces to forcefully transform himself into the "strongest Native", able to contend with the likes of Shadowborg and Hyper Beetleborg and overpower them. He had the ability to shoot electric bolts from the protrusions on his shoulders, and was physically strong enough to swat away Boron and Beetleborg effortlessly. However, once Boron destroyed his shoulder protrusions, he was severely weakened, and he was destroyed by Hyper Beetleborg and Boron's (Double) Rider Kick.
