no you can evolve rhydon
You cannot get Rhyperior in Pokemon emerald as he is only in Pokemon diamond and pearl.
You get your Rhyhorn to evolve into a Rhyperior.(Pokemon 188 is Rhyperior)
Rhyperior is a 4th generation Pokemon and therefore yo are not able to attain this in fire red. Diamond and Pearl however do have Rhyperior.
you have to do the Pokemon league 100 times and then you have to catch a wild rhyperior without getting a rhydon trust me ive done it and its hard
rhyperior doesn't evolve it is the 3rd and last evolsion
No, Rhypherior is not a legendary. Although he is one of those rare evolutions of common pokemon, he is not legendary, due to the fact that he evloves from a reflector, and is not naturally classified as legendary by The Pokemon Team and Nintendo.
