Behavior
One can say that Rhyhorn has rocks for brains because it can only remember one thing at a time. A perfect example of this is whenever a Rhyhorn starts charging, it'll forget why it did so in the first place.
Rhyhorn debuts in the Red, Green & Blue chapter in Raging Rhydon as Koga's Pokémon. After getting defeated by Red's Pikachu, Pika, it's forced to evolve with a mysterious injection.
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.

Although Rhyhorn's species is the "Spikes Pokemon," It cannot learn the move Spikes.
