Yes, but they fight as 1 team: double battle.
In Pokémon Omega Ruby and Pokémon Alpha Sapphire, the Pokémon that the two Mossdeep City Gym Leaders (Liza and Tate) will have once you challenge them to a battle and it will be a Double Battle will Lunatone and Solrock, Solrock will be at Level 45 and it will know moves such as Solar Beam, Sunny Day, Psychic and Rock Slide and Lunatone which is also at Level 45 and it will know moves such as Calm Mind, Hypnosis, Light Screen and Psychic.
== == Steven's house is in Mossdeep city two houses left from the gym by the two trees where the boy is.
In mossdeep city you have to go two houses at the left of the gym and you,ll find dive by steven.
It could be anywhere between Mossdeep and Lilycove. The dark sea parts can be dived into but you need HM08, which is dive. Get it from Steven in Mossdeep (he's in the house at the top-left corner of Mossdeep). Just talk to him and he will give it to you. But you need to defeat the Mossdeep Gym to use dive. The Gym leaders use Psychic/Rock type Pokemon. You need a Dark or Water type Pokemon to have an advantage against them. P.S. Believe me, I had a Wailord in level 40 and I still had difficulty defeating the Gym leaders. Remember, the Gym leaders are twins so they use two Pokemon at the same time. SO put your strongest Pokemon at the top of your Pokemon list. Good Luck!
The 7th gym is located in Mossdeep City and the leaders are Tate and Liza. This is the only gym with two leaders, so you'll enter a double gym leader battle. The gym is psychic-type, so use dark and ghost types. Their Pokemon are Claydol, Xatu, Solrock, and Lunatone. Also, the gym has certain panels to rotate certain tiles around and some teleporting tiles to teleport from room to room. One room has blue and brown panels and rotating tiles so NOTICE the green switch tile and then notice you can see the next room with rotating tiles. As you know there are four, so rotate it until the two statues aren't in the way anymore so you can get though there when you do get there. Your reward is 8400, Calm Mind and the gym badge. Good luck my friend!
Guess what you need at least 2 strong Pokemon because the gym leader is actually gym leaders meaning there is two that's because there twins so you have to have at least 2 strong Pokemon to verse them and win.
Then you will just fight with 1 Pokemon vs. Two foes Pokemon's Just like when you encounter a dual-fight with one Pokemon
Well~ Due to vagueness of the question, I will tell you two different answers. 1.) It's located in Mossdeep City, east of Lilycove, across the ocean 2.) Well, I can't really tell you much, except ACTIVATE ALL THE SWITCHES. I also guarantee you'll fight every other trainer apart from the gym leaders in the gym.
it was about two or three of the gym leaders
In mossdeep city you have to go two houses next to the gym and get TM dive by steven go on the black part around sootopolis and use dive.
talk to the lady in cianwood city she is the gym leaders wife she will give you fly.when you have defeated the gym leader on cianwood island, talk to the girl just outside the gym
The seventh gym is in Mossdeep City led by Psychic-type users Tate and Liza—yes, there are two, which means it’s a double battle. Their only two Pokémon are Solrock and Lunatone but easy as that may sound, it can be a nightmare if you’re ill-prepaared.
