No, unless you have a National Pokedex you might find a trainer who has one in the Battle Tower.
I have beat the game and have not found any trainers with a mawile.
Ash did but the tears of the pokemon brought him back to life.
no nobody in Pokemon platinum have a doexys.
Find the whirlpool tm give it to totodile (if you have it)or any other water pokemon.
No, only in Pokemon gold and silver. Maybe one day they'll remake those games.
No
There is no Lumineon in diamond
yes
The Sinnoh League Champion "Cynthia" has a Spiritomb.
use a master ball if you haven't got any u cant
Totodile is one of the three starter Pokemon in Pokemon Heart Gold and Soul Silver. To get a Totodile in any other Pokemon version you must trade it from Gold or Silver.
cheat
Im not sure but u can catch krabby during swarm.
If you really want to, use your masterball because it never fails. Masterball fails on other peoples Pokemon. I learnt from my mistakes... you cant catch trainers Pokemon it wont work with any type of poke ball(it would've been cool if you can catch trainers Pokemon though=)
Sorry No you can see some of the johto league Pokemon on Pokemon diamond and pearl if you go to the battle tower. ive seen a totodile and a cynaquil already. ;)
If you start off with Totodile, your rival will have the Chikorita evos.
An Ace Trainer in Victory Road on floor B1F has one. Sorry, scratch that, the Metang only appears in Pokemon Platinum.
