Battle a few trainers until you get to about level 24 (so you can take 2 hits from absorb) and stock up on super potions.
Use mud shot to lower grovyle's speed on the first turn. Second turn use mud slap to lower its accuracy. Now use a super potion each turn until grovyle misses, then use mud slap to further lower its accuracy.
Repeat until you get six mud slaps in (four or five may be enough). By now it can't hit the back door of a barn and you can kill it off with tackle.
After you best the game (Beat Rayquaza) you go alone with your mudkip to the town square and notice that there is a hole in the ground, you go in it you ask to evolve it evolves you into a marshstomp or Swampert if it evolves you into a marshstomp just do it again and you will evolve into a Swampert
dusknoir was really easy because i was a 73, but most people are about a level 35 to 45 at that time. i just train at the marowak dojo a lot. p.s. i was a pikachu and my parters at that time were turtwig and grovyle
You first have to beat Story Mode. And to do that, you have to beat the final trainer in Stargazer Coluseum (I can't spell it) who is the Poketopia Master. I beat him using the Cool Boy with Haunter, Rotom, Mightyena, Sandslash, and two others I forgot. After you beat the Master, you can use Level 50 rule! (Or you can go to a Free Battle and set a custom rule to 50 All.
You can beat Skyla the gym leader with a higher level pokemon or with electric or rock type pokemon. And I do not reccomend using grass or bug types.
i beat it with lvl 37 and 38
If it is Rival's Grovyle, evolve your starter a lot.
noob
teach it ice or poison attacks
You can train it to level 29(which sucks) so it can learn leaf blade. Or catch a geodude in dewford tunnel. A machop or makuhita would work, too, to take out magnemit and magneton. If you still have absorb on a high level grovyle, keep using that. Even an aron would work well as electric moves would do little damage. Just keep trying, I had grovyle, and I couldn't beat the gym until he learned leaf blade.
To beat May, the best thing to get is a Roselia and train it really high. It learns Mega Drain @ lv.17
You can't catch him but there is a way to get one. First beat the Elite four and defeat Red. Once you have done that get one of the three Kanto starters from Prof. Oak. Next go to silph. Co and talk to Steven stone. He will ask what is your favorite gem colour. Pick green to get a Treeko. Level Treeko up to level 16 to get Grovyle.

You don't. You need a strong water type or a strong flying type to beat it, a ground attack will do well too.

You can beat level 38 on 40x escape by spelling out the word ESCAPE using the scoreboard (liquid crystal display, as on calculators).
I beat rupert using a level 14 teffla Areos 10 and a level 12 pelro it was quite easy
