WarGreymon

WarGreymon is Mega form and Final form of Agumon.

Appearance
Unlike his other previous forms, WarGreymon's appearance takes form of a large dragonoid/humanoid form, donning gold "Chrome Digizord" Armor and possessing 2 clawed gauntlets called the "Dramon Killers/ Dramon Destroyers".

And despite being the shortest size among the 2 previous digivolutions, WarGreymon is the strongest among the three form, officially dubbed as "one of the strongest Digimons in existence", WarGreymon surrenders great size for greater speed and strength.
