What Pokemon can beat gym leader juan on Pokemon emerald?

Hmm. Well, considering he has Whishcash, Kingdra and the natural water type, you're best with Electric (Manectric, Plusle, Minun, Pikachu, Raichu etc) and Grass type (Sceptile, Nuzleaf, Even the Lotad family works if trained well... ) And for Kingdra, you're better off not using an Altaria or a Salamence since Kingdra is equipped with Ice Beam. You can even use a Swampert, as they have a lot of special defense and can even hold up against Kingdra. Just watch out for its evil Double Team. Hmm.
