Gumdramon

Gumdramon is a Mini Dragon Digimon whose name and design are derived from "Gum Dramon". It possesses an elastic Shippodzuchi (尻尾槌) that can extend anywhere. Its body is also very soft and elastic, and it moves around dynamically using its whole body like a spring. It is also able to fly at its running speed with its tiny wings. Its personality is very mischievous, so it's a showoff. In order to attract attention, it dives right in the middle of any kind of dangerous situation and rages around, not stopping until it stands out from everyone. Its potential is concealing its considerable, unfathomable power, but is inhibited by the "Kinkoji" (緊箍児) it wears on its tail.
