Alphamon

Alphamon
Alphamon, a Holy Knight Digimon, is not just one of the Thirteen Royal Knights but also their legendary leader. He is a Digimon of great power due to his possession of the "Alpha-Gain-Force". However, this very same factor has deemed him "Lord of the Empty Seat"; as he is destined to rule the Royal Knights but to be forever absent from their ranks. Thus his fate leaves to make only temporary appearances wherever his aid is needed.

Alphamon wears a blue cape similar in design to Omnimon's. He wields the "Alpha Inforce", which is an ability that allows the user to gain the power of invincibility by repeating attacks the user wouldn't have understood before, thus rewriting the course of history. Therefore, while many see the opponent being deleted in a final blow, it is really Alphamon laying on attacks that successfully delete the opponent. Moreover, variegated attacks and defensive maneuvers can be shown through a magical square that appears from his hands, which is carved in "Digi-Code".

Alphamon's name is a reference to "alpha", the first letter of the Greek alphabet. This creates a thematic link with himself and Omnimon, whose Japanese name is Omegamon&mdash;effectively, a reference to the concept of the Alpha and Omega.
