Pikachu does not evolve by level in any Pokémon game, including Pokémon Platinum. Pikachu evolves into Raichu when a Thunder Stone is used on it.
go to the main mt. in the game and level it up by 1 and it will evolve
it does not evolve at a specific level, you have to trade it to a Diamond, Pearl, or Platinum game and level it up by one in mt. coronet
Ponyta evolves to Rapidash at Level 40 in just about every Pokemon game. :)
Togepi evolves when its hapieness metor is full. Then level it up and it will evolve into Togetic. Give it a shiny stone after if you want it to evolve into Togekiss From, The Game Wiz
Level20, As it always does in every other Pokemon Game.
It Dos Not Tell you in Pokemon Diamond Pearl and Platinum
Trade it to another game while holding the Up-Grade.
I know for sure on Pokemon Platinum Version that Remoraid evolves at level 25. I'm not sure if that's correct on Diamond or Pearl, but I know it for sure on my Platinum game. Me and my cousin both have Platinum. We were both playing it on DS and he got it to level 25 and it evolved into Octillery.
You have to evolve a Chimchar, which you can get at Professor Rowan's Lab at the beginning of the game. Chimchar evolves into Monferno at level 14. Monferno evolves into Infernape at level 36
swinub evolves into piloswine at level 33. to evolve it into mamoswine go to the move teacher in pastoria city, give him a heart scale and teach piloswine ancient power. level it up after that and it will evolve in to mamoswine From, The Game Wiz the only swinub i can find so far is a level 34
It evolves at level 18 and not 16. If you are playing a Mystery Dungeon game, it will not evolve until post-game.
