After a bit of readjustment, I went to Mount Lanakila, where who else would show up but Gladion! He wanted to challenge me to thank me for saving Lillie and Lusamine. He started with Crobat, which dealt a little less than 1/4 with Acrobatics to Tron before being OHKO'd with Zen Headbutt thanks to the Expert Belt. Zoroark was next and finished me with the Z-Move. I brought in Reverse and took a Night Daze for slightly over half, while Superpower OHKO'd. Then he used Silvally, which finished me with X-Scissor. I brought in Syrup, only to be swiftly OHKO'd with Crunch. I brought in Tablet, and used the Z-Move, Bloom Doom, on base of Grass Knot, which…left him with 1 HP!!! Then his X-Scissor did 90% to me. I finished him with Psychic. Lucario finished me with Quick Attack. I brought in Arsonist and took a weak Quick Attack before OHKO'ing him with Flamethrower. Then he was finally happy, and gave me a PP Max, then declared that he's happy to have us around.
Then it was time to go through Mount Lanakila! As far as trainers went, there was one annoying female Ace Trainer whose Effect Spore paralyzed Tron, and her Clefable used Minimize - good thing I had a Z-Move ready! Tron also once again proved its derpiness with missing against a Veteran's Lickitung. And we had a slightly annoying double battle with two Black Belts with a Bewear. Near the end, there was a Veteran who was dumb and repeatedly used resisted attacks against Arsonist. The last double battle was no problem, aside from a few annoying misses.
Once we were at the top, there wasn't much to do before we were ready to enter the league! I decided that Acerola would be first, as surprising as it may seem.
I began with Syrup against Banette, and used the Z-Move, Stoked Sparksurfer, against Banette, to OHKO it.
Next was Palossand. Not wanting to switch in anyone else, I stayed in and used Charm before she OHKO'd me with Earth Power. I brought in Reverse and hit with Hypnosis, then used Night Slash for a little over half with a crit as she continued to snooze. Night Slash failed to finish her off, and she continued to snooze. She healed, and banking on that, I used Hypnosis and hit again, luckily. Night Slash scored a crit for over half, and the next one wasn't but still finished her.
Froslass was next, and I opted to stay in, and she used Confuse Ray, but I still hit through it and OHKO'd with a crit Night Slash.
Dhelmise came after, and for that I switched in Tron as she used Energy Ball for 1/6, but that was me zoning out, yet I went for Zen Headbutt for a little over 1/4 as her Shadow Ball got me into the red before Leftovers. Another Zen Headbutt got her below half, but she finished me with Shadow Ball. I brought in Tablet and finished her with Shadow Ball.
Drifblim was last. For that I opted to stay in and use Shadow Ball for around 40% before she used Amnesia. My next Shadow Ball got her below half, and her Ominous Wind did a little less than half my health. I brought in Psychadelic, and she used Focus Energy, allowing me to finish her with Crunch for the win (and the unneeded critical hit).
I decided that next would be Olivia, feeling that I had more than enough to handle her.
I began with Tron, and she was somehow faster than me and used X-Scissor for 2/5, but Meteor Mash was an OHKO thanks to the Expert Belt.
Probopass was next, and not wanting to be met with a Thunder Wave, I switched out to Syrup, and sure enough she used Thunder Wave, which failed. Thunderbolt did 1/5 or so, yet her Earth Power actually did less than half. Then I used Thunderbolt again and got a critical hit AND paralysis to get her below half, and she got fully paralyzed. With that, I used Nasty Plot, but she had other ideas, using Sandstorm. Thunderbolt left her barely hanging on, and even with Earth Power and the sandstorm I managed to live, and she healed, while Thunderbolt did around 1/3 before sandstorm finished me. I brought in Psychadelic and used Aqua Tail, which didn't finish her, and she used Thunder Wave. She healed again, and I got fully paralyzed before the sandstorm subsided. I was still faster, and did a little over half before she used Sandstorm again. I hit through paralysis and finished her, at least.
Cradily came after, and I switched out for Reverse. Her Energy Ball did over 1/3, then I used Superpower for slightly less than half as she used Rock Tomb for a light hit and a Speed boost. Yummy. Superpower then finished her and had me with +2 Attack and Defense and +1 Speed before the sandstorm subsided…
But then Gigalith's Sand Stream set it right back up. Superpower did around 2/3, then she used Bulldoze and left me around 1/4, then after sandstorm, Night Slash finished her with a crit.
Lycanroc was last, and I opted to stay in, and thanks to all those boosts, Superpower finished her.
Then we had Kahili to contend with.
I began with Tablet against Braviary and started with the Z-Move, Shattered Psyche, which OHKO'd. Alright, not bad at all!
Hawlucha was next, and I opted to stay in, and Throat Chop left me with 5 HP before I OHKO'd her with Psychic.
Then we had Mandibuzz. I switched Tron into a weak Brave Bird, then she used Flatter to give me a pointless Special Attack boost and confuse me. I hit myself in confusion for basically the amount that Brave Bird dealt to me, then she used Brave Bird again (why?) before I hit with Meteor Mash for an okay hit. Then she used Brave Bird again for whatever reason before I snapped out of confusion and got her low with Meteor Mash. Bullet Punch didn't finish her off, and she used Brave Bird once again (WHY???), leaving me low on health. She healed, and I hit with Hammer Arm for not much at all before she used Brave Bird YET AGAIN and got me into the red. Meteor Mash got her below half. Then she used Brave Bird ONCE MORE and finally finished me. I brought in Syrup and finished her with Thunderbolt.
Oricorio came after. For that I opted to stay in, and while her Revelation Dance did a little over half, Thunderbolt was an OHKO thanks to the Magnet.
Lastly was Toucannon. I chose to stay in once again, and Thunderbolt was an OHKO. Whew!
Lastly was Molayne. I had barely used Arsonist in this Elite Four at all, but I figured this would be his chance to shine.
I led with him against Klefki, who started with Thunder Wave as I led off with the Z-Move, which OHKO'd.
Dugtrio was next, and I switched over to Tron, who took an Earthquake and lived with 1 HP (!!!), which allowed me to get in a light Bullet Punch before he finished me with Earthquake. I brought in Psychadelic and used Aqua Jet, which bested him, but Tangled Hair lowered my Speed.
Magnezone was next. I opted to stay in and use Aqua Jet to break his Sturdy, dealt around 1/5 or so before Thunderbolt OHKO'd me. I brought in Arsonist, and Thunderbolt did slightly less than half only for me to get fully paralyzed. Then he used Screech (uh okay???) before I hit with Flamethrower and finished him.
Bisharp came after, and I switched Tablet into a Night Slash that OHKO'd. I brought in Reverse, and Superpower got the OHKO.
Lastly was Metagross. I chose to stay in and use Night Slash, which did a little over half, and I took a Meteor Mash comfortably before finishing him with another Night Slash.
So that was the Elite Four! Some interesting moments, but overall not too tough in the big picture. I entered the final room, and as I sat on the throne, it looked like Kukui was going to be my final opponent… "Just kidding!" It was Hau! He was ready for battle alright, so let's give him one!
I began with Psychadelic against that Raichu, something I was very worried about, but I had an idea. He used Thunderbolt, which I lived with 1 HP because of my Focus Sash, and OHKO'd him with Crunch. Thank you Strong Jaw.
Decidueye was next. Yikes! I opted to stay in and use Crunch, which did around 2/3, before he wasted his Z-Move, Bloom Doom, which OHKO'd. Yeah, nice going, genius! I brought in Arsonist and finished him with Mystical Fire.
Vaporeon came after. I opted to stay in and use Mystical Fire, which didn't do much at all beyond lowering his Special Attack, and he missed a Hydro Pump. I used Mystical Fire again to get him to -2, but then he hit and dealt a little over half.
But then he switched over to Noivern! I used Wish, then switched over to Tron, who took a Dark Pulse for over 2/3, unfortunately, but Wish propped me up. Dark Pulse got me low, while Meteor Mash did around half on the dot. Then he finished me with Dark Pulse. I brought in Syrup, and after Dark Pulse did over 2/3, Volt Tackle managed to finish him, and recoil didn't finish me.
Tauros came next, and after Intimidate, finished me with Earthquake. I had to bring in Tablet and use Baby-Doll Eyes, and Double-Edge then MISSED because of the Lax Incense! But then he hit for over 2/3, and took recoil damage, but Psychic got him low. He healed, so I took the opportunity to use Morning Sun, leaving me near 4/5. Then I used Baby-Doll Eyes again, but Double-Edge still did well over half my remaining health. I used another Baby-Doll Eyes before he finished me. I brought in Arsonist, who was a little over half dead, and he used Earthquake, which I survived in the red thanks to those Attack drops, allowing me to use the Z-Move and finish him off.
Afterwards was Vaporeon again. I went for Wish, then he finished me with Hydro Pump. I had only Reverse left, and he used Charm, which doubled my Attack. Then I used Superpower to get him into the red and boost my stats even further. He healed, but no matter! Superpower got him into the red and boosted my stats further. He healed YET AGAIN, and Psycho Cut got him into the red. His last Hydro Pump got me to 1/4, but my Sitrus Berry propped me up and allowed me to finish him with Night Slash.
Lastly was Crabominable, who was indeed faster than me. He used Ice Hammer, which thanks to my +2 Defense, I lived with 10 HP. That allowed me to use Superpower, OHKO him and complete the challenge!
So I watched the closing credits play over the montage, and that was it! I completed the game.
