With the Elite Four and Champion defeated, I was able to take the S.S. Aqua to Vermilion City in Kanto. Once in the new region, I traveled to every city and defeated every trainer I could find, saving all of the gym leaders for later. While doing this I did all of the necessary sidequests, mainly fixing the Power Plant, waking up Snorlax, and getting the Magnet Train Pass. Eventually I had been to every corner of Kanto, so I decided to go ahead and take on all of the gym leaders. In order, I defeated Janine, Lt. Surge, Misty, Brock, Sabrina, Erika, and Blaine. Once I had earned all of those badges, I spoke to Blue on Cinnabar Island, flew to Viridian, and defeated him to earn my final gym badge.

After defeating Fantina, I flew to Jubilife City and surfed west to Canalave City, where I defeated my rival and the sixth Gym Leader, Byron. Then I dealt with Team Galactic at Lake Valor and Lake Verity. To get to Lake Acuity, I first had to travel to the northern tip of the Sinnoh region, Snowpoint City. After the slow trek through the snow to get there, I immediately went to the gym to defeat Candice, earning my seventh badge. Then it was time to deal with Team Galactic for a final time. I ran in to Jupiter at Lake Acuity, then flew to the Galactic Headquarters in Veilstone City. I worked my way through the headquarters and defeated Cyrus and Saturn to release the mirage Pokemon. Next I flew to Oreburgh City and spelunked through Mt. Coronet to reach Sky Pillar. With the help of my rival I defeated Mars and Jupiter, then took on Cyrus by myself. Finally, I caught Palkia with my Master Ball. Having saved the world, I flew to Pastoria City and traveled east to Sunyshore City, where I retrieved Volkner from the lighthouse in order to take him down and earn my final gym badge of the SInnoh region!

After defeating Ramos, I went south onto Route 13 and defeated Team Flare in the Kalos Power Plant, restoring power to Lumiose City! With the power back, I was able to revisit Lumiose and take on the gym, where I defeated Clemont and earned my fifth badge. Then I went on to Route 14 where I defeated my rival and visited the spooky house. Once I reached Laverre City I took on Valerie to get my sixth badge. I took on Team Flare once again in the PokeBall Factory, then proceeded east to reach Dendemille Town. After I got there, I backtracked a little to the Lost Hotel, where I caught my final team member, Klefki! After defeating the trainers I skipped on Rotes 15 and 16 and the Lost Hotel, I went to Frost Cavern to deal with Team Flare once again. With Team Flare gone and Mamoswine back on Route 17, I was able to ride it through the thick snow to get to Anistar City, where I defeated my rival and Olympia, earning my seventh badge. As I left the gym, I got a weird message on my Holocaster and flew straight to Lumiose City where I infiltrated Lysandre Labs and witnessed the activation of the ultimate weapon in Geosenge Town. I flew there, defeated Lysandre again, went through a lot of Team Flare Admin battles, caught Xerneas, and defeated Lysandre a final time. With Team Flare dealt with, I flew to Anistar City and traveled southeast to Couriway Town. There I defeated Professor Sycamore before traveling south to Snowbelle City, defeating Shauna, Tierno, and Trevor along the way. Upon arriving to the city, I discovered that the gym leader was away, so I traveled through the Winding Woods to find Wulfric hanging out in the Pokemon Village. I got him to go back to his gym where I defeated him to earn my eighth badge!
