So you may have become the Champion, saved the world not once but twice, and explored the entirety of Alola. What else is there to do in-between training your Pokémon to Level 100 and completing your Pokédex? Well, how about revisiting some of your favorite locations and seeing what’s changed? Starting with Melemele Island.
After completing Episode RR, if you interact with Meowth in your house on Route 1, an amusing event will occur. One of your mom’s neighbors will come along with her Meowth, resulting in a "battle" between your mom’s Meowth and the neighbor’s. Once the dust has settled, you’ll receive a PP Up .
Trip to the Lab
From time to time, you can battle Kukui at the end of the Pokémon League. But if you’d prefer to meet him outside of battle, you can simply visit his lab on Route 1. The first time you speak to him, he’ll reward you with a Lucky Egg if you’ve registered at least 50 Pokémon in your Pokédex.
This valuable held item boosts the experience points from defeating a Pokémon by 50%, making it easier to Level Up your Pokémon. Also, if you leave the lab and return, the Professor has another gift for you: TM90 Substitute . As explained, it creates a decoy by expending 25% of the user’s maximum HP.
If you visit the lab after completing Episode RR, Kukui and Lillie will divulge the findings of their research on Z-Moves to you. Afterwards, if you talk to Lillie, she will offer to become a Multi Battle partner in the Battle Free. This time around, she will assist you in battle with a Comfey and Ribombee.
That’s everything you can do on the ground floor. If you head downstairs and approach the punching bag in the nearby corner, you’ll receive a surprise visit from Kukui’s old friend, Molayne, and his Machamp. You don’t get anything from this visit, but it’s nice to see Molayne again, outside of the Pokémon League anyway.
Rematch with Hala
Previously in Sun and Moon, Hala was one of the Elite Four members, but he’s since been replaced by Molayne. That said, you can fight Hala at his full strength by heading over to Iki Town and finding him near the entrance.
Island Kahuna Hala
Likewise, Hala’s Machop has evolved into its final form, Machamp, which boasts excellent Attack and reasonable bulk, but has low Speed. This one can use Cross Chop for STAB, and Fire, Thunder and Ice Punch to combat a variety of common Types. Psychic and Fairy-types are the safest choices.
Bewear is an evolved Stufful with similar stats to Hariyama. Its Fluffy Ability weakens contact moves, but makes it weak to Fire. For attacks, it has Hammer Arm for STAB, Brutal Swing and Shadow Claw to hurt Psychics and Ghosts, and Dragon Claw as a party trick, maybe? Hit it with Flying, Fighting or Fairy-types.
Poliwrath is one of Poliwag’s fully evolved forms, possessing well-balanced stats outside of its mediocre Speed. Hala’s can use Waterfall and Brick Break for STAB, Poison Jab to knockout Fairies, and Payback to beat up Psychics and Ghosts. Grass, Electric and Flying-types are all favorable picks.
Finally, Crabominable has stunning Attack, but suffers from the typical problem of low Speed. It can use Ice Hammer and Close Combat for STAB, Stone Edge to down Flying-types, and Earthquake to bash up Flying-types. It’s also equipped with Fightium Z. Psychic and Fairy-types are strongly recommended.
Topple Hala and he’ll reward you with the unique Z-Crystals for the two starter Pokémon that you didn’t choose . So if you chose Rowlet, for example, you’ll get Incinium Z and Primarium Z. Of course, to actually use these Z-Crystals, you’ll need to get trading for the other starters.
A Final Lesson
Near the beginning of the game, you had to study at the Trainer’s School for a short while. Although you’re definitely a Pokémon master at this point, there is one more important lesson to learn. First, head to the top floor of the school building and speak to the guy at the end of the corridor. He won’t budge without a fight.
Black Belt Duane
Through the door, you’ll meet the principal of the school. She’ll recognize you as the new Champion and doesn’t waste time in laying down the gauntlet.
The tough-looking Granbull is weak to Poison and Steel. Meanwhile Stoutland knows Fire, Thunder and Ice Fang, and can use Retaliate to damage Rock and Steel-types. It’s weak to Fighting-types of course. Finally, Arcanine has Reversal to counter Rock-types, so Water or Ground-types are advised.
Show Asuka what it means to be a Champion and she’ll offer you a King’s Rock in respect of your prowess. If held by a Pokémon, all attacks have a small chance of causing a flinch. It can also be used to evolve Poliwhirl and Slowpoke into their alternate forms if they’re traded while holding it.
