you have to trade from another game
you can find a Rhydon on route 226 :)
You need to evolve Rhydon. Rhydon evolves when you trade it when it holds a Protector. You find a Protector on Iron Island and Route 228. See related link on details on where to find Rhydon.
You can't find rhydon on a map or room so you must get a rhyhorn then train it to level 42 to get rhydon. You can find rhyhorn on certain rooms like FireredAddamsPokemonMansion.
Find a protector, and trade rhyDON, not rhyhorn, while rhyDON is holding it.
You can encounter a Rhydon on Victory Road on the first floor. A trainer on victory road will also have a Rhydon in his party.
get rhydon to lvl 38
30 something and it you cant find it in that game
you can find one in victory road.
On victory road you find wild Rhydon at about level 40. I don't remember where to find a trainer with one, but you could also battle a friend with one in the union room.
First, you must have Rhydon. Next, you must find the protector. Once you have them, give Rhydon the protector and trade it to another player. It will then evolve into a Rhypherior.
Do you have a high level rhydon, or just thinking of what rhydon evlolution is? Trying to evolve it? Hm... The answer is right here! Right now, and in the right place. If you have a protecter... You might be just lucky if you have a friend to trade the rhydon with the protecter. Hey! When you trade a rhydon with a protecter it's possible to trade pokemon, and the other user gets the different pokemon. Good luck!
Rhydon evolves into... RHYPERIOR!!
