Ghost Bug and Dark
See, electric type moves are effective against water Pokemon. Thunder or Thunderbolt are powerful attacks very effective against water Pokemon such as kingdra. ACTUALLY, since Kingdra is a dragon type too, electric type moves are just normally effective. Dragon type is super effective against Kingdra. But then Kingdra would be supereffective against you too!
Well, you don't NEED a water type at all. I went through Pokemon Emerald with a Torchic/Combuskin/Blaziken (and possibly an Azurill) but possibly a Dark type Pokemon because they are super affective against Psychic type Pokemon. NOT a Poison type Pokemon because Psychic type Pokemon are super effective against Poison type Pokemon. I REALLY hope that this answers your question!!! :-)
The first guy has dark Pokemon. Fighting is super effective against dark. The second guy has ghost Pokemon. Psycic is super effective against, but beware: ghost is super effective against psycic. The third guy has ice Pokemon. Fire obviously is super effective against Ice. The last guy has dragon Pokemon. Dragon and ice are super effective against dragon. The champion has water Pokemon, but one of his Pokemon is water and ground. Electric is very good against water, but it doesn't effect his water and ground Pokemon. Grass is very good to use against his water and ground Pokemon.
Dragon vs Dragon is best its super effective against each other if you believe me you try it. or ice.
you should probably get a ground typeand train it. ground is super effective and electric attacks will not affect it. i would say... probably a sandslash, andteach it earthquake.
By training youre pokemon to lv 55 at least and have good stormy attacks that are effective against Wallace like grass electric and psychic in tentacruels case
the best team for battle dome in Pokemon emerald is a grass type(against swampert , and a rock type(against charizard and salamance)
Fight, Fire and Ground.
Dragon and Ice types are super effective.
A fire and a fighting type Pokemon is good against steel.
slate port does not have a gym
i have a fire pokemon blaziken and i think it was level 40 but now was 56. my pokemon's attack was not effective but it was defeated. use water pokemon
