| Pokedex Entries: |
| Red | It massive bones are 1,000 times harder than human bones. It can easily knock a trailer flying. |
| Blue |
| Yellow | A Pokémon with a one-track mind. Once it charges, it won't stop running until it falls asleep. |
| Gold | It is inept at turning because of its four short legs. It can only charge and run in one direction. |
| Silver | It doesn't care if there is anything in its way. It just charges and destroys all obstacles. |
| Crystal | It can remember only one thing at a time. Once it starts rushing, it forgets why it started. |
| Ruby | RHYHORN runs in a straight line, smashing everything in its path. It is not bothered even if it rushes headlong into a block of steel. This POKéMON may feel some pain from the collision the next day, however. |
| Sapphire | RHYHORN's brain is very small. It is so dense, while on a run it forgets why it started running in the first place. It apparently remembers sometimes if it demolishes something. |
| Emerald | Once it starts running, it doesn't stop. Its tiny brain makes it so stupid that it can't remember why it started running in the first place. |
| FireRed | Strong, but not too bright, this POKéMON can shatter even a skyscraper with its charging TACKLES. |
| LeafGreen | It massive bones are 1,000 times harder than human bones. It can easily knock a trailer flying. |
| Diamond | Its body is clad in a thick hide, and its tackles topple buildings. Unfortunately, it is not smart. |
| Pearl |
| Platinum | Its powerful tackles can destroy anything. However, it is too slow witted to help people work. |
| Stadium 1 | Its bones are 1,000 times harder than human bones. Using its durability and strength, it can destroy tall buildings. |
| Stadium 2 | It is inept at turning because of its four short legs. It can only charge and run in one direction. |
