I don't know if you can but I know that if you put chimchar, monferno, or infernape in the daycare with a ditto an egg will appear and it should be chimchar
How Do You Catch Chimchar In Pokemon Platinum?
You can but you have to go to stark mountain and saerch it took me a few days.
You can't cacth it.. Just start with it in the begining of the game. .
You can Trade , I think do it with action Replay ds , Do it as begginer pokemon or get a ditto and get a chimchar or monferno ar Infernape to make a chimchar egg.
Just start the game with getting chimchar from Rowan
Get it as your starter
I get a chimchar
This is not possible without a cheat. I can't say any more because there is no more. Trade or cheat are your two option's.
You can gte a egg for it thats what I got a egg from the day-care couple
Get a action replay and theres a cheat that lets you catch Trainer pokemon. Battle a Trainer on route 216 I think and steal there chimchar
You can't catch chimchar you get to choose a pokemon at the start chimchar piplug or turtwig
You can put a chimchar with a ditto and they will have an egg. But I know you can catch a turtwig on route... Uh... Where spring path is. In the long grass. I've got all 3 starter pokemon and about 6 of each starter pokemon. :) :P :D
