Sou Otogiri

For the Original Kamen Rider TheBee see Kamen Rider TheBee

Otogiri So (Phylloxera Worm) is an influential member of Zect and the user of TheBee. With a chip on his shoulder in regards to Kabuto for taking his right eye, he secretly concocts a new scheme to finally take down the rogue Rider and consummate his vengeance.

Phylloxera Worm Form
A Worm that assumed the form of Souji before losing his eye to him as Kabuto, the Phylloxera Worm assumed the alias of Sou Otogiri, becoming head agent of ZECT and user of TheBee Zecter to transform into Kamen Rider TheBee to get his revenge on Souji. The fact that he resembled Souji had Mayu confuse him to be her brother before he reveals his true form while carrying out the Kabuto Capture Plan to get his revenge while ensuring that the Worms gain the advantage over the ZECT Riders. He is destroyed by Kabuto's & Decade's Rider Kick as they tear down the Clock Down broadcast tower in the process. The Phylloxera Worm originally appeared in the SmaSTATION special Kamen Rider G in which Decade and the other Heisei Kamen Riders make a cameo appearance at the end.
