I would suggest getting pickachu a high enough level to learn agility and getting a bunch of reviver seeds from sentry duty.
you have to defeat chimchar in the lava zone then he will appear there.
If your a Chimchar, and you know Dig, you'll do pretty good.If your a Pikachu, try Quick Attack, or maybe try some Sleep Seeds on Groudon, then attack it.
teach pikachu dig and then use it on dialga. it should do tons of damage my chimchar knew dig and did 350+ damage each time! killed dialga in 2 turn :)
Pikachu. It has a high attack, good against bosses (Excluding Skarmory) and it looks pretty cool. The downside is it learns moves S-L-O-W-L-Y. Plus Groundon has a fairly short temper with electric types... If you're in MD Explorers of Time/Darkness or sky, Chimchar always works for me. Just watch out for that Groundon.
Some Pikachu's can :P
you defeat maxie at his underground hide out
type in a password and go to the lava zone. to find this password and more go to pokeparkwii.com
Pikachu because it can learn discharge if you are a pikachu choose chimchar.... I love you kristin toedtman of bloomingdale NJ
