Agumon is partner to Lord of Water Toby Tripp & often counterpoints his partner. Although they are well both well-matched, Agumon is the more cautious one. They often have a strong bond and he always has the will to protect others even though he has to stop the others if they are brainwashed or something.
Agumon is much like his partner in that he can be kind and compassionate, but he is more serious than Tai. Though he can act rashly, Agumon is more cautious and less prone to getting into sticky situations, though he follows and protects his partner all the way. He can get philosophical at times as well, as he manages to help BlackWarGreymon question his purpose, and even maintains a strong bond with his dark twin. Agumon also shares Tai's main trait of being incredibly courageous.
