The Sevii Islands first appeared in Pokemon FireRed and LeafGreen. They served as post-game content with the inclusion of more Pokemon from Generation 3.
But this time, we’re going to show you how to get to the Sevii Islands in Pokemon Radical Red.
Yes, Pokemon Radical Red included these islands, but unlike in the mainline games, this location is a bit tricky to get to.
Reaching the Sevii Islands takes more than just finishing the game, but don’t worry because we’re here to help you with your quest!

Before Going to Sevii Islands, Finish the Game First!
You are still required to beat the game first by defeating the Elite Four and the Champion.
Once you have a Hall of Fame team, you can now do the requirements to get the Tri-, which is what you need to access the Sevii Islands.
How to Access the Sevii Islands in Pokemon Radical Red
There are several battles that you need to do to access the Sevii Islands:
IMPORTANT: Even before you finish the game, you can access some of the battles beforehand. This means that when you’ve already finished some of these battles, they already count. You don’t need to fight these battles again.
Talk With the Woman on Route 16


You must head to this woman NPC in the house on Route 16. You just need a Pokemon with Cut to access her house. The woman will tell you where to go in case you don’t know which battles you’ve finished.
The battles you already completed will no longer be mentioned by the woman. She will be a good aide if you want to know where to go.
Listed below are the battles that you need to do to get the Tri-.
Rematch With the Kanto Gym Leaders
Go and rematch the first 4 Gym Leaders in Kanto. If you don’t do it right away, Gym Leader Koga will not be accessible yet and will tell you that you need to rematch the previous Gym Leaders.
All of them are still found in their Gyms but are now armed with stronger Pokemon. They will reward you with some juicy items upon defeat.
Kanto Gym Leader | Location and Rewards |
---|---|
Brock![]() |
In Pewter City Gym, he will give you an Aerodactylite Mega Stone and TM71 Stone Edge. |
Misty![]() |
In Cerulean City Gym, when you beat her, she will give you a Gyaradosite and a Finizen Pokemon. |
Lt. Surge![]() |
You don’t have to do his puzzle again in the Vermillion Gym. He’ll give you a Manectite Mega Stone after you beat him. |
Erika![]() |
In Celadon City Gym. She will ask you to fetch medicine for her Gloom, which is available in Fuchsia City. Erika will battle you once you finish her quest. She’ll reward you with a TM86 Grass Knot and an Ogerpon. |
Battling the Johto Gym Leaders
The Johto Gym Leaders are scattered over Kanto. You may encounter them earlier, which is fine, and they’ll always be in the same locations armed with strong Pokemon.
Johto Gym Leader | Location and Rewards |
---|---|
Bugsy![]() |
On Route 25, which is north of Cerulean City, just below the Raid Den, which is also near Bill’s House. You may have encountered him early on by accident. He’ll give you TM89 U-Turn and 5 Nest Balls after you beat him. |
Chuck![]() |
Located in the Fighting Dojo on the left side of the Saffron City Gym. Upon defeat, he’ll give you TM 60 Drain Punch, a Black Belt, and a choice of either an Aqua Tauros or a Blaze Tauros. |
Jasmine![]() |
Located in the Cinnabar Labs, sitting inside. She’ll give you an Aggronite and Choice Band once you defeat her. |
Morty![]() |
Head over to Lavender Town, where Morty is inside Mr. Fuji’s House. Talk to him to start the battle. He’ll give you a TM30 Shadow Ball, Shed Shell, and a Soothe Bell. |
Pryce![]() |
This one takes place a bit later in the game since you have to fight him in the Seafoam Islands. You need to do a lot of things, like obtaining Surf. After you beat Pryce, he’ll give you a Glalitite and Choice Scarf. |
Whitney![]() |
She is located on Route 11, and all you have to do is head to the far right where there is the entrance to the split road leading to Routes 12 and 13. Once you beat her, she’ll give you a Normal Gem and an Eviolite. |
The Two Dumbass Trainers
There are two trainers having the Dumbass title. The woman on Route 16 will tell you to fight them.
Dumbass Trainers | Location and Rewards |
---|---|
Dumbass Kid![]() |
Located in a house in the northeast part of Saffron City. He is the one surrounded by the Mudkip evolutions. To start the fight, you just have to disagree with all of his questions. This will make him mad, and the battle will begin. He’ll give you a Mudkip after beating him. |
Dumbass Jojo Fan![]() |
This one is located in the Power Plant. There’s no puzzle to this fight, so just say yes, and he’ll battle you right away. You’ll be rewarded with a Machampite and Prison Bottle for all your efforts. |
Morty and the Gengarite
This is another requirement that you need to fulfill. The woman in Route 16 will tell you to go back to Morty to get a Gengarite.
When you get back to Morty in Mr. Fuji’s House in Lavender Town, he’ll simply ask you to show him a Pokemon with high enough Friendship/Happiness.
Morty will give you the Gengarite, and you’re good to go.
Heading to the Sevii Islands

Once all the battles are finished and you have the Gengarite, the woman in Route 16 will give you the Tri-.
Head to Vermillion City and talk to the sailor where the SS Anne used to be. You will then have access to Islands One to Three.
Choose to go to any of them, as you now have access to the Sevii Islands.
IMPORTANT: Right now, there are only three islands to explore because the game doesn’t contain the others. If you haven’t completed the main story yet, even if you have the Tri-, you won’t be able to access the Sevii Islands just yet.
In Closing
Getting to the Sevii Islands in Pokemon Radical Red does take some time.
These trainer battles are no joke, as they are armed to the teeth and will offer challenges. There’s no need to rush as well, since you still have to beat the main game.
It’s beneficial if you can fight and beat them ahead. The items they give can be useful to some degree.
Pokemon Radical Red has been completed, but who knows, maybe they’ll add the other Sevii Islands in the future.
