Viral Cores

Viral Cores are miniature car-like devices created and used by the Zenjox Computer Network for the purpose of sustaining, empowering, and evolving their existence. They are evil counterparts of the Auto and Moto Chargers.

The Zenjox Computer Netowrk later gain access to the Neo Cores, completely red-colored variants of the standard Viral Cores which will allow them to combine both Attack-Bot and human biology into one.

Normally, Viral Cores are used by the Attack-Bots to evolve them from their weaker Low-Class forms into their stronger Advanced forms. Low-Class Attack-Bots can also use three at the same time, or two at the same time if they have already evolved into an Advanced Bot, to transform into a Giant Attack-Bot based on their motif. When Chase was originally Auto Rider, he could use the regular Viral Cores, presuming they were not too damaged, to read the memories of defeated Attack-Bots by inserting them into his Shift Brace. Like the Attack-Bots, the Viral Cores come in three types.

Chrome versions of the Viral Cores, known as Mech Cores, are used by Auto Rider's rival, Mech Warrior, to change into his Defender forms. Unlike the regular Viral Cores, these ones were created by Chase as a means to learn about their power.

Regular Cores

 * Cobra Core: A Viral Core that can give a new body for the Cobra-Bots‘ core, though when three are used instead, it allows the Attack-Bot to evolve into a giant cobra.
 * Spider Core: A Viral Core that can give a new body for the Spider-Bots‘ core, though when three are used instead, it presumably evolves the Attack-Bot into a giant spider.
 * Bat Core: A Viral Core that can give a new body for the Bat-Bots‘ core, though when three are used instead, it presumably evolves the Attack-Bot into a giant bat.

Mech Cores

 * Cobra Mech Core: A man-made Viral Core that summons the E-Circular Module and turns Mech Warrior into his Cobra Form, equipping him with the whip-like Tail Whip. When initiating Triple Form, Mech Warrior inserts this Core last.
 * Spider Mech Core: A man-made Viral Core that summons the E-Circular Module and turns Mech Warrior into his Spider Form, equipping him with the pincer-like Spider Fang. When initiating Triple Form, Mech Warrior inserts this Core first.
 * Bat Mech Core: A man-made Viral Core that summons the E-Circular Module and turns Mech Warrior into his Bat Form, equipping him with the crossbow-like Wing Sniper. When initiating Triple Form, Mech Warrior inserts this Core second.

Neo Cores

 * Neo Bat Viral Core (ネオバットバイラルコア): An advanced Bat Viral Core that can be used by a Bat-type Roidmude to combine with a human. First appears in Kamen Rider Drive Vs. the Terrifying Zunbo Ganbo Roidmude to evolve Roidmude 007.
