Its body is clearly massive, and its fangs and claws conceal a deadly ability, but though its appearance is ferocious, it is a Beast Digimon which possesses the spirit of an honorable martial artist. It can nimbly dodge the opponent's attacks, turning them aside, as with its exceptional grappling sense it doesn't need to rely on its own attacks. Though Gryzmon never starts fights, once someone makes it angry it will stand up on its back legs and knock them down with its heavyweight forelegs, "Kuma Tsume". With just this blow, most Digimon suffer a mortal wound as strong as the power they possess. These "Kuma Tsume" appear to have been imitated in Waru Monzaemon's "Bear Claw" equipment. Its Special Move is a bold move in which it knocks down the opponent by utilizing their attack power, and conversely strikes them in a weak spot (Atemigaeshi).

明らかに大きな体、殺傷能力を秘めた牙と爪、見た目は凶暴だが正々堂々とした武闘家の精神を持った獣型デジモン。体の割に素早く敵の攻撃を避けたり、受け流すなど、攻撃に頼らない抜群の格闘センスを持っている。決してグリズモンから争いを起こすことは無いが、ひとたび怒らせると二足で立ち上がり重量級の前足「熊爪」を殴り落す。この一撃だけで殆どのデジモンが致命傷を負うほどのパワーの持ち主でもある。この「熊爪」を真似てワルもんざえもんが「ベアクロー」装備しているらしい。必殺技は敵の攻撃の力を利用して、逆に急所をついて一撃で倒す大技『当身返し』。
