Zatch Bell! Attack of Mechavulcan

A mysterious figure, Dr. M2, gathers a team of Death Mechanics and orders Death 18 to abduct Kiyomaro. The machines resemble gigantic robotic versions of Vulcan, signaling a plan to pull Kiyomaro into the future demon world.

Kiyomaro wakes up late and races to catch the bus to Coast School, leaving Gash behind. His friends try to warn him as the tension builds, underscoring ordinary life before the extraordinary threat arrives.

Death 18 swoops down and kidnaps Kiyomaro, lifting him away from the street in broad daylight. Gash and his friends watch in shock as the powerful robot disappears with Kiyomaro.

Inside Dr. M2's lab, Kiyomaro is trapped in an orange energy bubble. Dr. M2 explains his plan to take Kiyomaro to the future demon world, while Death 18 is sent to distract Gash.

On the way home, Gash reflects on previous Vulcan generations ruined in the past, reinforcing the idea that each is a true friend. Naomi, the town bully, misinterprets Gash and attacks, but Death 18 intervenes.

Death 18 repairs Gash's Vulcan, leading Gash to believe he's a fellow Vulcan named Yondaime (Fourth Generation). Gash and the repaired Vulcan ride into town in Yondaime's giant mouth.

In his lab, Dr. M2 shows Kiyomaro a future Vulcan prototype and explains how the Death Mechanics are meant to be fixed. Kiyomaro questions whether the Demon World ruler's battle still matters, but M2 remains noncommittal.

Gash and Yondaime take refuge under a bridge where they paint graffiti and meet Gash's demon friends. They form a small, joyful gathering before the looming threat returns.

Dr. M2 opens a portal to the future, causing a dark cloud to loom over the city and prompting mass panic as citizens evacuate. Yondaime's programming resists at first but eventually accepts helping Gash.

The four demons and humans board the mouth-propelled Vulcan into battle as a giant Vulcan forms from the castle. Megumi, Folgore, and Sunbeam arrive to help fight the giant, exchanging powerful spells in the sky.

Kiyomaro snatches Gash's Vulcan, reminding him that Vulcan is a toy, while Gash reaches a heartfelt realization that Vulcans are his friends and that Kiyomaro's real victory is their friendship. They resolve to protect the Vulcans instead of destroying them.

Kiyomaro, Dr. M2, and the four demons coordinate to lure the giant Vulcan's power into the reactor. They attempt to close the hole by feeding it Baou Zakeruga, but the plan initially falters as the reactor resists.

Yondaime flies up and attaches to the reactor, while Gash and Kiyomaro strive to guide the power. The Vulcan prototype carries Kiyomaro's recorded voice, providing a guiding message between them.

Gash and Kiyomaro launch Baou Zakeruga, which tears through Yondaime and activates the reactor, closing the time-space hole. The giant Vulcan collapses and reverts to the smaller Vulcans.

With the hole closed and the Vulcans returning to the skies, Gash asks if he will see Yondaime again. Kiyomaro promises to build him an even better Vulcan, symbolizing the enduring bond of friendship that drove their actions.
