Digimon Adventure 02
Some Guardromon are under the control of the Digimon Emperor's Dark Rings in Full Metal City. One blows up the Digi-Port to the Real World before Kari Kamiya and Gatomon can make it through. Later on during this event, a Guardromon shoots down Nefertimon before Flamedramon and Pegasusmon deactivate them all. After Andromon successfully fights the control of the Dark Ring, he blows up the Control Spire, afterward reactivating and reprogramming the Guardromon. One Guardromon is among the Digimon seen during the final battle against MaloMyotismon.

Digimon Tamers
Separated from the others Rika's group encountered an Andromon who was trying to liberate a village of Gekomon from the control of Orochimon, who had enslaved them to mix sake for him (milkshakes in the English dub). Andromon was badly injured in the battle with the Tamers taking him to the Gekomon village, where they eventually managed to convince the Gekomon leader to give them some of the data packets from their drinks to heal Andromon. However, he had lost much of his energy from the fight and regressed into Guardromon as a result. He helped the Tamers rescue Jeri Katou from Orochimon by conducting a plan of stowing away inside the drink barrels to get onto Orochimon’s island undetected. After Orochimon was destroyed, Guardromon became a Digimon partner to Kazu who helped out in the battles with Beelzemon and the D-Reaper.
