Hydrasect is a colorful female bee-like monster that mistook a foreign exchange student for Dex. Hydrasect had the ability to fly with the wings on her head. Hydrasect can shapeshift into an even more powerful form known as Arachnida, the second form of Hydrasect. Arachnida was a large 4-legged inhuman spider woman who has a set of spider legs on her back and two spider legs for a left arm. Arachnida can shoot strong webbing to entangle Masked Rider. The monster was unlike any Dex ever encountered. During combat with the monster, he learned that her spider legs were hollow. By snapping one, it instantly killed her.
- Hydrasect is based on "Bee Woman" from Kamen Rider J. Arachnida is based on "Kumo Woman" from Kamen Rider ZO. Hydrasect was also one of only two monsters to be used in U.S. Footage (the other being Robo Rider).
