Crimson Creeper

A black-haired crab monster with a strong-clawed right arm. He also has a toxic breath attack. While Dex was helping Albee train to beat the arcade ace Henry Wall, Count Dregon sent Crimson Creeper down with Double Face to capture Dex in order to steal the Masked Rider powers. Dex fought both of them in the first battle and called upon Combat Chopper for help. During a challenge against Henry Wall, Combat Chopper alerted Dex that Magno detected the Crimson Creeper attacking an amusement park. Dex chopped off Crimson Creeper's arm before he used his toxic breath on him. Dex counter-attacked with the Rider Kick before destroying Crimson Creeper with the Electro Saber. He fits the category of Double Face's unit.
