Gallantmon X

Gallantmon X is a Gallantmon modified by the X Program.

Digimon X-Evolution
He is a member of the Royal Knights but because he questions the intentions of the host computer, Yggdrasil, he acts 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 and gave Dorugremon safe passage to Yggdrasil while joining the battle with other Digimon against an endless swarm of Death-X-Dorugremon. Later on, he met with Omnimon X on top of a mountain.
