Character History

Kamen Rider Kabuto

Initially duplicating a guard it killed, Rubor was part of a large group of Salis Worms that were attacked by a squad of ZECTroopers. It first molted with the other Aracnea Worms (Nigritia and Flavus), easily overwhelming the ZECTroopers and escaping. Later spotted by a pair of detectives, it killed them and duplicated one, strangely a Salis Worm again. It tried to attack a girl, but ZECTroopers arrived and intercepted it, forcing it to molt into Rubor again, easily fighting through them before Tendou arrived and transformed into Kabuto for the first time. He fought it in Masked Form, and though it Clocked Up, he saw it coming by aiming his Kabuto Kunai Gun's laser sights through the dust and glass shards in the air, tricking it into impaling itself on his Kunai's axe blade, destroying it.

  • It is unclear why this Worm was seen molting twice. Either the Aracnea sub-class has the exclusive ability to un-molt, or Worms staying molted simply hadn't been decided upon as of the first episode's production.
