Digimon Tamers
Gallantmon Crimson Mode appeared towards the end of the series, when the group was battling the D-Reaper. Gallantmon found himself overwhelmed in his battle, and seemed to be at its mercy. But then, Grani, whose body was deteriorating, arrived. Claiming that his time with Guilmon and Takato had allowed him to feel as though he was truly alive, he lent them the last of his power, transforming Gallantmon into his Crimson Mode. With this newfound power, they were able to defeat the D-Reaper's Agent-01.

Later, when the swarm of Parasimon attacked the real world, Gallantmon again mode changed, and used his Crimson Light attack to destroy the Digital Zone they were coming from.

Gallantmon Chaos Mode
Gallantmon Chaos Mode is a "opposite number" to Gallantmon Crimson Mode, created for a toy release by Bandai of America. While its status as an official Digimon is in dispute, its colorscheme suggests that it is ChaosGallantmon's answer to the normal Gallantmon's mode-change.
