It appears that Graveler is a living, bipedal boulder. Its skin becomes tougher when it evolves. It also has four arms, but mainly uses the longer two to lift things, using the shorter two as a defense against attackers.
They often roll down mountain paths at high speeds, crushing objects in the way. Despite growing legs, it can revert to a form similar in nature to Geodude, granting it the ability to float and lose two of its arms. If it breaks or shatters, it has the ability to restore itself overtime.
Graveler are notable for their habit of tumbling down mountains, heedless of any obstacles as they simply roll over them. Their preferred locomotion is rolling, specifically because it is a slow walker. With a free and uncaring nature, it does not mind if pieces of its body break off as it rolls. If Graveler gains too much speed, it stops by running into huge rocks. Graveler climbs a mountain from base to summit, feasting on rocks all the while. Upon reaching the peak, Graveler rolls down to the bottom.
Graveler can be often found on mountain trails or in caves. They are very common, appearing in Kanto and Johto.
A Graveler's diet mainly consists of rocks. They especially like rocks covered in moss.
