Digimon 02
He debuted when the Digimon Emperor cut a swath of destruction across the Digital World with Kimeramon. Magnamon then engaged Kimeramon, heavily damaging Ken's fortress in the process. But Kimeramon eventually got the upperhand. Wormmon, in a last attempt to stop his friend and make him see the error of his ways, managed to free Magnamon and then gave him his lifeforce. Magnamon, re-energised by Wormmon‚Äôs sacrifice, used his Magna Explosion attack to destroy Kimeramon.

Hurricane Touchdown/Supreme Evolution! The Golden Digimentals
He appeared, along with Rapidmon, to fight Kokomon in the form of Kerpymon. Their attacks did little damage, as Kerpymon continuously healed himself after each injury and then swallowed the two Digimon. Inside of him, guided by the small part of him that was still untainted, Magnamon and Rapidmon killed Kokomon to end his suffering on the Digimon's behalf.

V-Tamers
Yolei, Cody, T.K. and Kari within Parallelmon helped Davis to remake the Digi-Egg of Miracles and Veemon became Magnamon and destroyed that monster.

Digimon X-Evolution
One of the Royal Knights loyal to Yggdrasil, Magnamon was the one who captured Dorugamon {By kidnapping Tokomon X}. He brought him to the super computer so it could extract his data for Project Ark. Magnamon would go by any means to fulfill his mission, no matter who stands in his way. Of the three remaining Royal Knights, Magnamon is the most loyal to Yggdrasil: he attempts to rationalize his Lord's actions when even Omnimon starts to demand answers to troubling questions considering the true nature of Project Ark.

But he relucantly stood down when Dorumon turned out to be the reincarnation of Alphamon.
