I can't beat Groudon in Pokemon Mystery Dungeons: Explorers of Time.?

Question

I'm a level 25 Mudkip and my partner pokemon is a level 25 Pikachu. Help?

Answer 1

Have you tried using alot of sleep and stun seeds?

Answer 2

Keep using sleep seeds or stun seeds and keep battling groudon more and more until you beat em also carry revival herb and lots of oran berries.

Also level up until you reach level 35 because thats how i made it to when i kept doing missions and after that you can beat em easily but still you must carry oran and rivival herbs as well as max elixir when you run out.
