Alphamon

Alphamon
Alphamon is a Warrior Digimon whose name is derived from. While it is one of the "Royal Knights", it is said that to Holy Knights it is a being like a deterrent force, and in normal times it doesn't appear, so it is sometimes called the "Aloof Hermit" with a fluttering blue mantle, and is the Royal Knight that is assigned to the place called the "Empty Seat". In battle, it possesses the ability for the ultimate force, "Alpha inForce" (from Alpha Gain Force), which instantaneously replays the battle's past, so although Alphamon's attack are over in just an instant, you can't grasp how many attacks it actually unleashed, and in theory, you can only see the final blow that brought down the opponent. It can expand a magic square of DigiCode from its hands, which attacks and defends. It wields the "Seiken Gradalpha" (聖剣グレイダルファー), which is based on Grademon's "Souken Gradalpha" (双剣グレイダルファー)).
