Dracozolt is a hybrid fossil Pokémon. It has a small yellow upper body with two long wings shaped like lightning bolts on its arms. Dracozolt has a long neck that connects to a paravian-like head with closed eyes and a red spot on each cheek. The upper half is connected to the middle of the lower body, with an orange and yellow circle surrounding the neck. The lower body is colored pink and green. The legs are green with pink toes and stripes and the tail is green with pink stripes and spikes.
It generates electricity thanks to its powerful tail muscles. It allegedly overgrazed its plant-based food sources, causing it to eventually go extinct, though this is likely not the case due to Dracozolt being combined from two separate Pokémon that each had their niches before going extinct.
Dracozolt, like its counterparts, may be based on the concept of chimera in paleontology, which refers to fossils reconstructed from multiple different species or genus of animals, resulting in an inaccurate and mistaken understanding of the animals's biology. In the case of Dracozolt, its top half appears to be based on a dromaeosaurid, while its bottom half appears to be based mainly on a stegosaurian. Dracozolt and its counterparts may also reference the Crystal Palace Dinosaurs, a series of scientifically inaccurate dinosaur sculptures displayed at the Crystal Palace Park.
The Pokédex entries for all the Galarian fossil Pokémon mention them being the cause of their own extinction, which may be a reference to the outdated hypothesis that the dinosaurs were evolutionarily inert, which made them get bigger, stupider, and more sluggish, to the point they couldn't sustain themselves.
Dracozolt being unable to breed could be a reference to cross-bred animals, which are born infertile (unable to produce offspring).
Dracozolt may be a combination of dracō (Latin for dragon) and volt or jolt.
Patchiragon may be a combination of パチパチ pachipachi (onomatopoeia for crackling) and dragon.
