MagnaAngemon is a humanoid digimon clothed in white. He has a cross-emblazoned forehead guard with wings on either side that cover his eyes, and he has the sign of peace on his belt. On his back are two large wings. When he goes into battle, he dons battle armor that makes him look just like other MagnaAngemon.
MagnaAngemon is the one who brings Taichi Yagami to the Digital World so he can help him and the other good Digimon fight Daemon. He lives in Holy Angel Castle and, along with Whamon, governs the Digital World. He is one of the Support Programs to help the "Vaccine" Taichi defeat the "Virus" Daemon. During Neo Saiba's invasion on his castle, he appears in his battle armor to get rid of some of the enemy digimon. To face Arkadimon, he attempts to use Heaven's Gate to seal him away, but Arkadimon breaks the attack, so MagnaAngemon reveals that he has the ability to digivolve to Mega, only that he sealed the power away so as to not make the other Digimon uncomfortable due to his aura. He digivolves to Seraphimon.
Upon Seraphimon's defeat, he reverts to his MagnaAngemon form to recuperate. When Neo attacks again, MagnaAngemon digivolves to Dominimon to help out.
- Excalibur: Draws the Excalibur blade from his right wrist.
- Heaven's Gate: MagnaAngemon's Gate of Destiny; draws a circle in the air to suck all enemies into another dimension.
After Arkadimon was able to break through his Heaven's Gate attack and then digivolve to Champion, MagnaAngemon digivolves to Seraphimon to fight Arkadimon. Unfortunately, Arkadimon is stronger and is able to defeat Seraphimon and revert him back to his MagnaAngemon form.
During Neo's second attack, MagnaAngemon digivolves to Dominimon against Daemon's army together with Leo as Regulumon and Hideto Fujimoto's Omnimon. While he is able to defeat most of Daemon's henchman, he is heavily wounded by Arkadimon in his Mega form but manages to survive.
