You'll need to trade for it, because it isn't on the maps.
ryhorn
AHH by fire stone or king stone
You cannot get Rhyperior in Pokemon emerald as he is only in Pokemon diamond and pearl.
ive never heard of Pokemon indigo but you cant get rhyperior without trading.The quickest way would be to look for someone willing to trade a rydon at what ever level you want it with a protector at the global trade centre
Entei can be found in Nimbasa City in Pokemon Indigo.
Rhypherior wasn't created yet when Pokemon Ranger came out.
Yes, there is every Pokemon on Indigo. The easiest way to find Pokemon is to go to the ROOMS.
I doubt you will find Giratina on Pokemon indigo as it is not a generation 1 Pokemon (it isn't one of the first 151 Pokemon species)
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.
NERD!
You find it in pokemon! it's obvious!
