Dragapult's appearance is reminiscent of both ancient lepospondyls such as Diplocaulus and modern stealth bombers. It has a triangular, wing-shaped head, a relatively short body, and a long, laterally flattened tail similar to a newt's.
The dorsal side of Dragapult's flattened head and the anterior half of its body are a dark navy color which fades to a teal on its posterior end & tail. The lateral, wing-like crests of its head are pink. The ventral portion of its head and body are a light yellow-tan color, and its belly is marked with three pink chevrons angled toward its head. It has four hollow, triangular horns and narrow yellow eyes. Its limbs are relatively short and thin, and are clawed. The claws on its forelimbs are pink. Dragapult's tail becomes transparent and ethereal toward its tip.
Dragapult carries a pair of Dreepy inside its horns, which it will fire at its opponents like supersonic missiles during battle. It's said that the Dreepy it carries greatly enjoy being sent flying toward opponents at immense speeds. Much of Dragapult's behavior beyond this, however, remains a mystery.
Dragapult is the lightest pseudo-legendary Pokémon, as well as the tallest.
Dragapult is the only pseudo-legendary Pokémon that cannot learn Earthquake.
If Dragapult Dynamaxes, it will temporarily disappear before reaching its largest size.
Dragapult may be based on the Diplocaulus, an extinct amphibian with a similarly-shaped skull. A complete tail has never been found in a Diplocaulus fossil, which may explain Dragapult's ghostly, translucent tail. Its head also resembles a B-2 Spirit, a stealth bomber aircraft. Its name and propensity for holding and firing Dreepy may be a reference to projectile weapons, such as catapults and crossbows.
It may also be a reference to the paternal care behavior present in many amphibian species. The Dragon typing may be a reference to the Olm, a type of salamander native to central and southeastern Europe that was believed to be a dragon offspring by locals.
Dragapult and Doraparuto may be a combination of dragon and catapult.
