Guardromon

As an android, Guardromon is a protector by nature, a mechanical defense specialist who faithfully fights for justice and protects the computer network. However, he tends to be rather foppish and frequently unlucky in his endeavors. When combined with the "Net Keeper", Giromon, he has the defensive efficiency of an iron wall. There are times when evil hackers utilize it to protect them. His name is sometimes spelled as Gardromon.

Guardromon's armored body is made of solid iron. He also has rocket jets mounted on his back.

The Guardromon were shown in a flashback with a bunch of Mekanorimon led by Dark Masters leader Piedmon when raiding a building that the Digi-Eggs of the 8 DigiDestined Digimon were held in, but a younger Gennai made off with them.

Digimon Adventure 02
Some Guardromon were under the control of the Digimon Emperor's Dark Rings in Full Metal City. One blew up the Digi-Port to the Real World before Kari Kamiya and Gatomon could make it through. Later on during this event, a Guardromon shot down Nefertimon before Flamedramon and Pegasusmon deactivated them all. After Andromon fought the control of the Digimon Emperor's Dark Ring, he blew up the Control Spire, reactivated and reprogrammed the Guardromon. One Guardromon was among the Digimon seen during the final battle against MaloMyotismon.
