bug
Have a good Fire and/or Ground Type...
Hmm.... By the Pokemon League I assume you mean the Elite Four? Aaron (Bug Type) Bertha (Ground Type) Flint (Fire Type) Lucian (Psychic Type) And the Champion is....... Cynthia (Various Types)
Bug, ghost, dark. Psychic moves do not effect dark type Pokemon what so ever, so if it is a gym, or league (if you have Pearl or diamond it is there is a psychic league person. it is the 3ed one) i recommend a dark Pokemon. i think the 3 league leader is actually a fighting type Pokemon user.........
Your best bet is: A Water type An Ice type A Flying or Fire(or Moltres) A Dark or Ghost type(or Spiritomb) A Grass type A Rock type Hope this helped!
First Elite Four member is Aaron, who uses Bug Type. The first Pokemon he uses is Dustox.
um i cant really tell you cause i don't exactly know but you can type teleportion to the Pokemon league it doesnt really matter if its in platinum diamond or pearl
if you choose the grass starter then your rival will have an infernape or when you go to the Pokemon league , the 3rd elite four is a fire type user . he will have an infernape.
