well, of course, magneton is a problem, so try your best on him. go catch a shroomish and evolve it at level 23 and he gets mach punch which slams magneton and then use leech seed on his others and try as hard as you can
if this does not work, you should start again with this team, they match up like this
torchic-combusken///vs. magneton
shroomish-breloom///voltorb
ralts-kirlia-mabey even gardevoir///manetric
poochyena-mightyena///electrike.
if you use mach punch and breloom is strong enough you should beat voltorb with seeing selfdestruct. also, your team should be in the very low thirties
noob
Wattson is easy as long as you have a ground type Pokemon like Marshtomp and use ground type moves like mud shot or have a grass type Pokemon like Grovyle or Breloom.
If it is Rival's Grovyle, evolve your starter a lot.
You make sure Holmes isn't there and get a big stick.
Peekachoo
teach it ice or poison attacks
First beat the Mauville Gym leader, Wattson.
At new mauville after you beat your dad go to wattson and he'll give you directions
To beat Grovyle with Marshtomp, you can leverage Marshtomp's Water/Ground typing, which gives it a strong advantage. Use Water-type moves like Water Gun or Mud Shot to exploit Grovyle's Grass typing, as they deal super effective damage. Additionally, Marshtomp's bulk allows it to withstand Grovyle's attacks, giving you the opportunity to outlast and defeat it. Be sure to keep your health up and prioritize hitting hard with your Water-type moves.
You don't. You need a strong water type or a strong flying type to beat it, a ground attack will do well too.
lavaridge town, use your pokenav. just go north of where you fought wattson
You can't get him to join you... BUT... in the end, when you beat primal dialga, you will unlock the final special episode you can play the game as him. The whole gang'll be there, sableye, primal dialga, spiritomb, dusknoir, celebi and Grovyle. If you aren't talking about the one who was your friend when you were human, then there's a grovyle in mystery jungle. look at serribi.net (sorry if I misspelled it)
