There are two ways of which I know, one, use the Exp. Share, which means (incase you didn't know) that in battle the EXP. Is shared between two Pokemon and what I do, is now I've beaten the elite four, keep fighting them and you level up really fast and get lots of EXP for it too
By defeating all 8 gym leaders.
You can do that by keep on battling with that Pokemon, or using a specific type of berry.
you cant do that in pearl but in platinum
There is no rental Pokemon in in Pokemon platinum
Pp max are items you use to restore your pp if it's low or zero.im not sure if you can buy them but I'm positive it will restore your pokemons pp fully
In the National Pokedex in Pokemon Platinum Mawile is Pokemon 303.
Right, You cannot get an pp max in Pokemon diamond or Pokemon pearl nor platinum!
You can do that by keep on battling with that Pokemon, or using a specific type of berry.
