After Larvatron dropped his disguise, Dex became Masked Rider and severed the robot's head with the Rider Kick. However, Larvatron had a backup head: a powerful four-way cannon.

Count Dregon had Nefaria send the Maggots to lure Hal and Albee towards Mothitron during their bug hunt. Once that plan worked, Mothitron used his moths to infect the two of them. Slowly, Hal and Albee, who were immobilized by the attack, took on the characteristics of an Insectovore (claws, green skin, bug eyes, etc.). Ferbus, though, was able to escape and warn Dex. Using a butterfly Ferbus had caught, Dex created an antidote. As Masked Rider, Dex took Magno and the antidote to Hal and Albee's location, but then he was ambushed by Mothitron. During the battle, Magno tackled Mothitron and took Masked Rider to the cave. Once inside, while looking for Hal and Albee, Dex was attacked by Mothitron again. Dex chopped off Mothitron's tongue, but Mothitron still overwhelmed Dex. Magno tunneled into the cave to save Dex.

Robo Rider was silver and black with green eyes. He also held two swords in battle. Robo Rider attacked the school causing Dex to transform and fight him. Robo Rider retreated and confronted Count Dregon on why he sent Edentada down to Earth.

During the confrontation, Robo Rider forced it back in the cave. It starts to cause earthquakes when it starts to get hungry for Masked Rider causing Count Dregon to send Nefaria to stop its hunger strike. Masked Rider finds the cave that Edentada is in and fights it before Nefaria arrives with Cyclopter, Double Face, and Gork to bring Edentada back.

Cycloptor said that it would be out of control, but Count Dregon says that he'll see how Termasect does with Masked Rider. Dex as the Masked Rider found Termasect and confronted him. After an attack from Termasect, Dex changed into his Super Gold form and summoned Combat Chopper (who was then transformed into Super Chopper).

- Voice Actor: Sparky Thornton
During a clean-up campaign in Leawood, Cyclopter's Reanimator Ray revived a fallen robot called Cyclotron.

In addition to interchangeable arms, leg cannons, and metallic wrappings emitted from a compartment in his torso, he also had the power to control any electrical appliance. Using two cars, he seemingly killed Masked Rider with a missile launched from his right leg cannon. Recyclotron then attacked Leawood with reanimated appliances. Hal took it upon himself to go after Recyclotron with a Catho-Destabilizer weapon he invented. Unfortunately for Hal, Recyclotron took control of the Catho-Destabilizer until Masked Rider arrived. After a fierce fight, Dex managed to kick off his cooling helmet and knock him down with the Rider Kick. Dex then destroyed Recyclotron with the Electro Saber.

Dex transformed into Masked Rider and used Magno to trace the mist back to the source. Dex engaged Fire Bug at the factory. Fire Bug dragged Dex into a room where it started a fire.

Hydrasect is a colorful female bee-like monster with wings on her head. Hydrasect had the ability to fly with her wings and shoot needles from her hands. When Nefaria told Count Dregon that they need an Insectivore that is cunning, Count Dregon considered using a shapeshifter called Hydrasect. When launched from the Spiderbase, Nefaria, the Maggots and later some Commandoids accompanied Hydrasect to monitor the progress. The Commandoids mistook a Scandislavian exchange student named Bjorgy as Dex (due to him wearing one of Dex's Jackets) and took him to the quarry where Hydrasect was waiting. Upon learning this, Dex transformed and went after them. When Bjorgy encountered Hydrasect, she thought he was Dex until he arrived. While Bjorgy hid, Dex engaged Hydrasect and managed to knock out her out of the sky for a short time. Upon throwing Dex into her chamber, Hydrasect shapeshifted into an even more powerful form known as Arachnida: a large 4-legged inhuman female drider who had a set of spider legs on her back and two spider legs for a left arm.

During the fight, Dex ends up hitting the Red Fusion Beam and ends up in the Spiderbase's tractor beam with Robosect. Dex broke free from Robosect's grasp only to be blasted from the tractor beam by Robosect. After being located by Ferbus, Magno, and Combat Chopper, Dex is informed by Magno that Robosect is detected in the sub-basement of Leawood's Ancient History Museum.

In Count Dregon's latest attempt to steal the Masked Rider powers, Double Face stumbled upon an idea to use a tractor beam to bring Dex up to the Spiderbase. To help out, Count Dregon has Nefaria have the Skull Reapers "escort" Dex into the tractor beam. When Ferbus is left behind at the motocross park, Dex heads there to save him only to be ambushed by the Skull Reapers. This tactic works as Dex ends up a prisoner of Count Dregon. Upon learning of Dex's capture, Magno and Combat Chopper emit some energy to overload the Spiderbase enough for Dex to escape. Count Dregon orders his minions to send the Skull Reapers down to help recapture Dex. As the Skull Reapers show up on their motorcycles, Dex transforms and fights them on board Combat Chopper.

Heliotoid
- First Appearance: "The Heat is On" (2/17/96)
- Voice Actor: Ed Neal
A robotic insectoid monster whose heat manipulation abilities caused an immense heat wave which caused Ferbus to fall ill. Heliotoid does this by getting its energy from the sun in which Count Dregon hopes that Heliotoid will become strong enough to destroy Masked Rider. To counteract with Count Dregon's plot, Hal started inventing the Quantum Cooler to help make things cooler. To keep it from being complete and thwarting Heliotoid, Nefaria and the Maggots were sent to make sure it isn't completed which doesn't go well for the Maggots.

During the second fight, Dex fought Cycloptor and Electrosect. While Cycloptor retreated, Electrosect started to drain Dex of his powers.

A jellyfish-like monster with lots of tentacles to attack with and a teleportation ability. When Count Dregon notices Dex using his powers to race to school, Double Face comes up with a plan which involved a Mass-Molecular Transfer Machine that they claimed from one of the planets Count Dregon conquered as well as a powerful crystal. To assist in a plot to capture the population of Leawood and enslave them on Edenoi, Count Dregon unleashed Tentaclon to hide the machine from Dex until it was ready. When Dex detected the activity, he arrived only to be ambushed by the Maggots unleashed by Tentaclon. After the Maggots were defeated, Tentaclon attacked. After a brief fight, Tentaclon disappeared alongside the Maggots, the Commandoids, and the Mass-Molecular Transfer Machine. When the crystal was charged up, Tentaclon had the Commandoids install the crystal into the Mass-Molecular Transfer Machine. When the test run is complete, it is sensed by Dex who manages to slip away. Dex ended up fighting Tentaclon again who kept teleporting in battle. When Tentaclon gets Dex in his tentacles, Combat Chopper saves Dex. When Tentaclon disappears again, Combat Chopper managed to detect him.

Dex detected Blue-Fanged Louse at the power plant and became Masked Rider to fight him. Dex managed to get overwhelmed by Blue-Fanged Louse even when Dex's Rider Kick energy is absorbed. When it absorbed the Masked Rider powers upon Gork's arrival, it was too much for the Blue-Fanged Louse enough to regress it to the size of a louse. This enabled Dex to get away on Magno. Upon hearing a suggestion from Gork, Dregon sent Blue-Fanged Louse and three Commandoids incognito as a band named "Battle Cry" at the Battle of the Bands contest. Battle Cry's music was causing immense tremors around the arcade. Dex discovered their true forms and cut the power enough for Blue-Fanged Louse and the Commandoids to escape. When Dex catches up to them, Blue-Fanged Louse assumes his true form and ends up attacking the city as it absorbs the energy attacks from the Spiderbase. Dex transforms and fights Blue-Fanged Louse.

While the Stewarts try to coral Ferbus even when he grows, Dex and Combat Chopper end up fighting Cycloptor on his upgraded Cannon Wheels. When Dex is on the defensive, Count Dregon sends Cyborsect to assist Cycloptor. The attacks of Cyborsect and Cycloptor's Cannon Wheels was enough to knock Dex off of Combat Chopper.

As Super Blue, Dex could easily maneuver against Twister Bug who managed to escape. During their second fight at the quarry, Twister Bug almost had Dex in his Super Blue form trapped by burying him alive in a large ant hill.

After some attacks from Dregonator, Dex then transformed into his Super Gold form whose Ecto-Ray attack wasn't enough to phase the Dregonator.
