Druddigon is a large, blue, hunchbacked, reptilian creature with medium-sized wings shaped like thistle leaves. It has a set of glaring, ferocious irises. Its arms are longer than its legs, giving it a low-slung, sloping gait. It has a thick, medium-length tail and sharp claws on both the hands and feet. Its head is colored bright red, and has several blunt horns and spikes jutting out everywhere. It also has tall, conical spikes—similarly colored red; three on each arm, one on each shoulder, two on each leg, and four on its tail. It has a blunt, brutal snout, bearing a maw with no discernible teeth; instead, small fang-like protrusions sprout from its jaws. Its eyes are pale yellow. It has a series of olive-colored, football-shaped scutes running across its belly.
Its bright red head is very hard, being harder than rock. It nimbly chases prey around its den, using its outstretched claws to catch them. Druddigon is also carnivorous.
It's Sheer Force raises the base power of all moves that have a positive secondary effect by 30%, the secondary effects are ignored. However, this ability is not applied to moves that have a negative effect on the user, such as recoil, two-turn moves, and stat reduction after using certain moves. If a Pokémon with Sheer Force is holding a Life Orb and uses an attack that would be boosted by Sheer Force, then the move gains both boosts but the user receives no recoil damage.
