Alpha-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.Omega-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.Y: It is inept at turning because of its four short legs. It can only charge and run in one direction.
Prof. Lotus' Notes: Despite Bulbasaur being Bulbasaur being the first Pokemon in the Pokedex. Rhyhorn was actually the first Pokemon ever to be designed.
