Rustboro City Gym – Roxanne
Pretty much every single trainer in this gym uses rock type Pokemon – including their leader Roxanne – so bring along some Pokemon with water, grass, ground or fighting type attacks. If you chose Treecko or Mudkip at the very beginning you’ll likely go through this gym like a hot knife through butter. If you started out by taking Torchic at the beginning of Pokemon Omega Ruby & Alpha Sapphire however, this gym can be a little more difficult. Unless you’ve evolved it to Combusken and taken on a Double Kick.
It’s always nice to have a back up though right? If you catch a Slakoth in Petalburg Woods, you can trade it with the boy in a house east of Rustboro Gym to get your hands on a Makuhita. This fighting type Pokemon is resistant to rock damage and able to dish it out with some full-on fighting type slamming.
Roxanne herself poses little threat as the first Gym Leader you face in Pokemon Omega Ruby & Alpha Sapphire. Her team consists of a Geodude and Nosepass. Bring along anything with water, grass, or fighting abilities and they will fall to the wayside with ease.
It should also be noted here that if you accept the Beldum Mystery Gift offered during the launch window for Pokemon Omega Ruby & Alpha Sapphire, its Ironhead skill is also super effective as it is of the steel type.
After defeating her you get the Stone Badge which means any Pokemon you use in Pokemon Omega Ruby & Alpha Sapphire up to level 20 will listen to you and TM39. This TM is Rock Tomb, a rock attack which also reduces the opponent’s speed.
Dewford Town Gym – Brawly
The trainers in Dewford Town’s Gym love Pokemon with a little fight in them. All of their Pokemon are of the fighting type so make sure you’ve got a few flying, psychic, or fairy abilities bouncing around in the party. Catching a Wurmple and evolving it into a Beautifly or Dustox will grant easy access to a pair of powerful attacks to make taking down Brawly a piece of cake. Both of them are able to learn Gust (flying) and Dustox has the added bonus of learning Confusion early on. Torchic along with its evolutions and flying Pokemon like Taillow can also offer easy access to flying attacks.
Brawly uses a level 14 Machop before switching to a level 16 Makuhita. They are both of the flying type and neither poses a huge threat alone if you’ve got any of the three attack types listed above available to you. While not the first Gym Leader, Brawly is perhaps the easiest of Pokemon Omega Ruby & Alpha Sapphire when you have some psychic or flying power behind you. Do take note however, he holds a super potion that can be used to restore 50hp to either of his team. Hit him good and hit him hard.
Like before, if you use the mystery gift Beldum it has a psychic ability named Zen Headbutt which will cause tremendous damage to each of these fighting type behemoths. Brawly’s gym is somewhat hard to traverse but if you walk down the clear routes after pressing each light switch you’ll progress through in no time. From the entrance head left, then right then left through the darkened portions to easy reach him.
After defeating the Dewford Town Gym you’ll obtain the Knuckle Bag which forces all Pokemon up to level to obey you and TM08: Bulk Up. Sticking this onto a Pokemon with high HP will make your journey though Pokemon Omega Ruby & Alpha Sapphire a little easier.
Mauville City Gym – Wattson
Right off the bat, all of Wattson’s Pokemon team are Electric type so don’t bring anything of the Water or Flying type up against him. If you do, a bad time will be waiting in your future. Against his first two Pokemon a fire type Pokemon will help as they are strong against electric and steel. The final member however is pure electric death so bring along a ground type to really cause him some issues. It’s likely you won’t have any ground type Pokemon right now in your journey through Pokemon Omega Ruby & Alpha Sapphire but there are some out there to be found. Nincada on Route 116 is a ground type and so is Geodude of the Granite Cave. Out of the two, get a Geodude and take the fight to Wattson.
Wattson’s Pokemon; a level 19 Magnemite, level 21 Magneton, and level 19 Voltorb, are all equipped with the same ability. This ability is Volt Switch. It allows them to deal damage to your Pokemon and then jump back into its respective Pokeball before calling forth another. Since they are all electric type attackers, expect an unhealthy amount of paralysis to land on anything that isn’t a ground type. If you are using any Pokemon that aren’t of this type, give them a Cheri Berry to hold or stock up on Paralyze Heals.
Gather up whatever ground type attacks you can muster so far in Pokemon Omega Ruby & Alpha Sapphire and settle in for a possibly aggravating battle as there aren’t many Pokemon at this stage in the game with the power to wipe the floor with Wattson’s electric family. Like Brawly before him, Wattson carries a Super Potion so if you don’t wipe out one of those crackling critters outright, expect it to be healed next turn.
Defeating Wattson and his Mauville Gym trainers nets you the TM for Volt Switch which you’ve likely already seen in action. You’ll also obtain a Dynamo Badge which unlocks new items to purchase, the ability to use Rock Smash outside of battle and dominion over all Pokemon under level 40.
Lavaridge Town Gym – Flannery
Flattery will get you nowhere, neither will a failure to prepare for Flannery’s fiery faction of Pokemon (yes I’m paid by the alliterative sentence don’t kill me). She may be a new Gym Leader but her flaming temperament is not to be sniffed at. Since all of her Pokemon share a fire type and the skills to match, bringing some water Pokemon into the battle is without a doubt the best way to deal with the heat.
Use those fishing rods you’ve been getting to fill up a party of water Pokemon. Keep in a couple of wild cards capable of psychic or flying attacks because several of the trainers within her Lavaridge Town Gym have a tendency to use Medatite. Earlier on in Pokemon Omega Ruby & Alpha Sapphire you’ll have been given the opportunity to catch Wingull or its evolved form Pelliper. Sharing both the flying and water types, these birds are able to soar through whatever Flannery’s understudies can muster.
If you’re really stuck for water type Pokemon, try loading up a fighting Pokemon with the Bulldoze TM (which can be purchased in Mauville City) for a highly powerful attack which can decimate these flame-ridden foes.
Her level 26 Slugma, level 26 Numel and level 28 Torkoal are capable of an especially powerful ability called Overheat which causes stupendous amounts of damage to the opponent at a cost of the user’s Special Attack stat. Don’t run the risk of being burned by this. Make sure whatever you have at your disposal is Super Trained in speed and holding a Quick Claw if possible.
Defeating Flannery will ensure that any Pokemon up to level 50 will obey your commands while allowing Strength to be used outside of battle throughout Pokemon Omega Ruby & Alpha Sapphire. As soon as the battle is over, head east on Route 112 to grab the nugget hidden behind a huge stone block. She will also give you the Overheat TM for use on your own fire type Pokemon to quell any enemies you face.
Petalburg City Gym – Norman
Norman’s the name, Normal’s the game in the Petalburg City Gym. Facing up to your father is often one of the scariest times for a growing teenager. Luckily in the world of Pokemon it doesn’t have to be. Norman uses a level 28 Vigoroth and long with 2 Slaking (1 at level 28 and the other at 30) to stop trainers dead in their tracks. What makes these such a trick for some teams though is not that they are incredibly powerful in any way, it’s that they’re completely Normal.
Normal Pokemon only have one weakness and that’s fighting attacks. Bring along any fighting Pokemon and Norman should be pretty easy. If you didn’t pick up the traded Makuhita from before or capture any Pokemon with fighting abilities before, going to Jagged Pass or Route 112 right now is a good idea. There are plenty of Machop running around there to be caught, along with several others throughout Pokemon Omega Ruby & Alpha Sapphire.
Get a fighting Pokemon or use something with Rock Smash and you’ll find your way through these big fluffy sods with relative ease. Make sure you’ve got the hitting power though. After one of Norman’s team has fallen, a move they all have called Retaliate increases exponentially in power. If you’ve got a Pokemon out the turn after one of Norman’s team falls and it doesn’t kill the enemy outright, expect it to faint.
After defeating Norman you are given a TM for this Retaliate skill. It has some good uses when in a team where you have a Pokemon with Self-Destruct but otherwise this ability isn’t exactly amazing. You’ll recieve a Balance Badge though, which forces any Pokemon up to level 60 to obey your commands. Don’t forget straight after this to pick up HM03, otherwise known as Surf.
Fortree City Gym – Winona
Flying Pokemon had long been a staple of any future Pokemon League Champion’s team. Not just for their power against bug, grass, and fighting types either. The move Fly has allowed trainers to soar around the world for decades upon their own flying Pokemon. As veterans of the franchise would expect, you can also use Fly in Pokemon Omega Ruby & Alpha Sapphire. To do that however, you’re going to need to defeat the Fortree City Gym Leader.
Known as Winona, she uses a fearsome foursome of Pokemon who all possess the ability to dish out flying damage. Her level 33 Skamory is joined by both Swellow and Pelipper of the same level. Her fourth and final Pokemon is a particularly vicious level 35 Altaria who is able to use a particularly powerful Earthquake. The reason I mention this is simple. Earthquake is a ground type ability which causes significant damage to electric Pokemon.
You’d be able to get through the majority of her team pretty easy with an electric Pokemon like a Electrike from Route 118 or the Cosplay Pikachu obtained from Slateport City after competing in a contest. Electric attacks won’t cause a great deal of damage to Altaria though so bring along a strong rock type Pokemon to finish it off. The Rock Tomb ability you got from Roxanne is more than capable of seriously harming this dragon/flying creature.
Don’t go all out with a rock type early on though. There aren’t many in Pokemon Omega Ruby & Alpha Sapphire I’ll grant you, but they will take a large amount of damage from her Pelipper. Go full-on shock at first with an electric type then bring the awe with a rock type.
Defeating Winona grants you the Feather badge which forces Pokemon up to level 70 to obey your orders and allows Fly to be used outside of battle. Winona also gives you TM19 which contains Roost. It’s a flying type move which restores the users HP by up to half its maximum health pool.
The Mossdeep City Gym is a strange one at the best of times. It’s full of weird and wonderful people using psychic type Pokemon, including the twin Gym Leaders Liza & Tate. Before even stepping foot into this Gym you should ensure you’ve got at least one well-trained dark or ghost type Pokemon within your ranks. Don’t bring along anything with a fighting or poison type though, because the psychic abilities used in this place will devastate Pokemon with them. If anything has a bug move or two they’ll also come in handy.
Liza & Tate battle you simultaneously in a pair battle. While this means you’ve got their level 45 Lunatone and Solrock at the same time, you can use a pair from your collections too. They are both rock and psychic types so they’re open to a wide variety of weaknesses including grass, water, and steel thanks to their rocky dispositions. It isn’t especially necessary but you should try to ensure that any attacks you intend to bring to bear on these two are physical attacks rather than special ones. Why? Well they will frequently cast Light Screen which reduces the damage taken form special moves for five turns.
They are both immune to ground attacks because this pairing has Levitate, but with a healthy use of attacks like Feint Attack and Dark Pulse you’ll be victorious in no time. Don’t split your focus on these two. Focus on one before taking down the other to reduce the amount of damage they can dish out.
Defeating this pairing nets you the Mind Badge which forces all Pokemon up to level 80 to listen to your commands and allows the use of Dive outside of battle. You’ll also receive the TM for Calm Mind, a move which boosts Sp. Atk and Sp. Def.
Sootopolis City Gym – Wallace
This is it. The final Gym Leader of Omega Ruby & Alpha Sapphire. Based in Sootopolis City, this Gym is full of water Pokemon and its Leader Wallace carries with him a team of 5 powerful watery critters. All being water types, they share a common weakness in grass type moves. The same could be said for electric types but his level 44 Whiscash shares water and ground attributes, making electric moves next-to-useless against it.
Grass Pokemon are not exactly hard to find throughout Pokemon Omega Ruby & Alpha Sapphire so if you’ve still not got one, go off for a short wander and you’re sure to come across one. These also have the added advantage of being incredibly resistant to pretty much every water type move Wallace can throw at you. Make sure to bring along some high-powered potions just in case anything gets through or deals critical damage.
His team comprises of a level 44 Seaking, Whiscash, Luvdisc and Sealeo, with a level 46 Milotic bringing up the rear. There’s no particularly special actions to look out for against these if you followed the previous advice of bringing something electric and grass.
Defeating Wallace grants you the Rain Badge which means all Pokemon, traded or captures, will obey you no matter what their level. You can also use Waterfall outside of battle. Where do you get Waterfall though? Well Wallace gives it to you for defeating him.
