Graveler is a bipedal, boulder Pokémon. Its round body is covered with small bumps and it has a rocky crest above its small eyes and mouth. It has four arms, each with a three-fingered hand. Its second pair of arms is typically kept tucked against its chest. It was shown in Pokémon Snap that, despite having legs, it can revert to a legless form. This grants it the ability to float.

Graveler's preferred locomotion is rolling, as it is a slow walker. It often rolls down mountain paths at high speeds exceeding 60 mph (96.56 km/h), crushing objects in the way and stopping by running into huge rocks should it build up too much speed. It does not pay attention to obstacles, so it may potentially harm hikers as it rolls. However, it will explode if it rolls into a river. Graveler is known to be generally free and uncaring, not minding if pieces of itself break off since they can regrow over time. It climbs a mountain from base to summit, feasting on rocks all the while. Graveler's favorite food is moss-covered rocks, regularly consumming tons of them and making loud noises while eating. Upon reaching the peak, it rolls down to the bottom. Graveler live in horizontal holes that they gouge out in sheer cliff faces, and they are capable of withstanding volcanic temperatures. As mentioned in Pokémon Sleep, Graveler is known to rock back and forth while sleeping. It is believed that it dreams about rolling down hilly paths.

Forms
Graveler has a regional form: Alolan Graveler.

In the Alola region, Graveler looks similar to its regular counterpart, but with a silvery sheen. It lacks defined digits on its upper limbs and has two toes on each foot rather than three. There are several small, yellowish crystals scattered across its body and iron sand attracted by magnetism. This black sand creates crystal-like formations above its eyes, across the tops of the upper pair of arms, and on the sides of its face.

Alolan Graveler has a very quick-tempered personality. It feeds on rocks, with its preffered food being dravite, which creates the yellow crystals on its body and grants it electrical abilities. It often fights with others over food, and when two smash together, they generate a flash of light and a booming sound; for this reason, people refer to it as "the fireworks of the earth". Similar to its Kantonian counterpart, Alolan Graveler rolls down mountain paths; however, instead of flattening obstacles as it rolls, it sends them flying by zapping them with electricity. They can be found in the Canyon Biome of Blueberry Academy's Terarium, where Alola's island life is simulated.
