prof.Oak who is in south west of eterna city says some Pokemon evolve by becoming friendly with their trainer.
by getting the national pokedex.
Beat the Elite Four and get the National Pokedex
you have to see all of them. i had trouble finding a wormadam holding trainer.
No trainer has a ditto.. if you want Ditto for your National Pokedex, use the Poke Radar on Route 218
I am not going to list the list here, but here is how to open it online:1. In Google, type 'national pokedex platinum'.2. Press 'return' or 'enter'.3. Click or Double click on 'Pokemon Platinum- The National Pokedex'.Then the Sinnoh Pokedex will appear (even though it says National Pokedex, it's the Sinnoh Pokedex with the location and/or a trainer with the Pokemon)!
You have to battle every single trainer if not true improve answer
No, unless you have a National Pokedex you might find a trainer who has one in the Battle Tower.
National Pokedex: Kabutops is the 114 Pokemon in pokedex. Evolve from Kabuto. Get Kabuto from Dome Fossil. Give Dome Fossil to guy in museum in Oreburgh City. Leave building. Go back in and talk to him. Sinnoh Pokedex: Mantine is the 114 Pokemon in pokedex. Evolve a Mantyke with a Remoraid in your party. Get Mantyke by surfing on route 223 he is also in a Trainer's party Pokemon on Route 218. Get remoraid by using a good rod on route 222. See it on a trainer on route 213.
You get trainer stars by completing in-game task. You must complete the Kanto Pokedex, national Pokedex, enter the hall of fame, 200 jumps in the Pokemon Jump, and collected 200 berries in berry picking.
beat a trainer and search the Pokemon up in your Pokedex
When you complete the sinnoh pokedex go over to Sandgem town and give your pokedex to Rowan and Proffesor Oak will give you the national pokedex where you must SEE every Pokemon that exists even the Pokemon that arent in Pokemon platinum.
you get to fight ash, but he apears as pokemon trainer red.
