Digimon Tamers
In Digimon Tamers, the first Biomerged Digimon (termed 'Matrix Evolution/Matrix Evolved' in the Japanese version), Guilmon became Gallantmon when Takato Biomerged with him so they could fight Beelzemon together. The ensuing battle was fierce but Gallantmon managed to defeat Beelzemon. However, Gallantmon did spare the hostile Digimon on Jeri's pleas. Gallantmon eventally was a major power in the battle against the D-Reaper, playing a key role in confronting it, obtaining the ARMS "Grani" as his mode of transportation until it gave Gallantmon the power to transform into Gallantmon Crimson Mode for the final battle against the D-Reaper.

Runaway Locomon
After a Parasimon captured Rika, Takato and Guilmon Biomerged to save her. They were able to save Rika but found out that the Parasimon that controlled Locomon was trying to get other Parasimon to materialize in the Real World. Henry and Rika Biomerged with their Digimon to stop them but even after Justimon arrived to help, they were greatly outnumbered. In the end Takato refused to give up and enabled Gallantmon to power-up to Crimson Mode, who then used his Final Justice attack to seal the hole the Parasimon used, causing all of the Parasimon to die.

Digimon Frontier
In Digimon Frontier, a Gallantmon was seen at the Autumn Leaf Fair running an armory there who was unable to help Zoe find the Toucanmon and the guys' D-Tectors (In the Japanese version, this one didn't talk).

Digimon X-Evolution
In Digimon X-Evolution, he is a member of the Royal Knights but because he questioned the intentions of the host computer, Yggdrasil, he acted individually. He tried to convince his close friend Omnimon that they were being used and that their Lord Yggdrasil's Project Ark was more than it seemed but Omnimon refused to hear it. The two Knights engaged in a brief battle in which Gallantmon was killed as a result; from his final words, it seems like his impalement on Omnimon's blade was intentional. However, Gallantmon was soon reborn as Gallantmon X.
