MasterGreymon is the lord of fire and the creator of the crest of courage. He is unmatched in terms of brute force and is extremely loyal to all friends of the Empire of Fire. He grew up with Magnamon while touring the Digital World to become Lord of Fire, and they have been friends ever since. Him and BarrageGarurumon have a rivalry going. Barrgae claims his accuracy would easily trump MasterGreymon's strength. They would have fought, but Magnamon stopped to ask for their help. He holds high respect for an Imperialdramon King Mode, for he is friends the two most powerful. He also has a deep hatred for demons.
