Post-Game content is available after finishing the Elite 4 and getting the credit roll in Pokemon FireRed and LeafGreen (FRLG). See all the post game content you can do, how to unlock the post game, where to capture Mewtwo, and more!
List of Contents
After defeating the Pokemon Champion and rolling the credits, the game will restart and you will be teleported automatically back in front of your house in Pallet Town.
| Post-Game Activities | ||
|---|---|---|
| National Pokedex | Get the Ruby and Sapphire | |
| PKMN League Rematch | Trainer Tower | |
The post game will unlock automatically, starting with the National Dex. In addition, the post game also unlocks more islands in the Sevii Islands. You can also go back to the Cerulean Cave to challenge Mewtwo and attempt to capture it.
Professor Oak will approach you as soon as you arrive back in Pallet Town and upgrade your Pokedex into a National Pokedex. This allows you to record Pokemon from other regions that you will likely encounter throughout your post-game adventures.
| 1 | Talk to Celio in One Island. You may take the ferry from Vermilion City to do this. |
|---|---|
| 2 | Go to Mt. Ember, past Kindle Road east of One Island. Mt. Ember is due north of Kindle Road. |
| 3 | After entering, immediately head east to see two Team Rocket Grunts guarding a cave. They are talking about a Team Rocket Warehouse, and they are only recalling one password: "GOLDEEN need log." Defeat both Grunts to enter. |
| 4 | Follow the cave path and head down the ladders until you get the Ruby. Note that you will need to have a Pokemon that knows HM Strength to progress. |
| 5 | Return to Celio in One Island and hand him the Ruby. Afterwards, he will then ask you get the Sapphire from another island. He will then hand you his own Rainbow Pass. |
| 6 | The Rainbow Pass allows you to go to more islands in the Sevii Islands, something only you can do in the Post Game. |
| 1 |
With Celio's Rainbow Pass in hand, go to Four Island first. In addition, your Rival will give you clues about Pokemon Eggs, alluding to the existence of a local Day Care on the island. Make sure to visit it and check it out! |
|---|---|
| 2 |
To the left of a Day Care is an item blocked by a breakable rock that you can use HM Rock Smash to access. Afterwards, head east of Four Island to see a body of water that you can use HM Surf on. Grab the Stardust to the left and go up to see a cave opening to the Icefall Cave. |
| 3 |
Once inside, enter the cave to the left of the waterfall to get items. Inside, the game will make you solve ice-related puzzles. For the first puzzle, just get the Ultra Ball and drop down on one of the ice floors to the north of the item. Choose the ice floor to the left. |
| 4 |
Here you will drop into an area with an ice floor. Climb up the ladder and fall on the ice floor nearest the ladder to get a Nevermeltice. Go back and climb the same ladder again and drop fall on the other ice floor farther from the ladder to progress. Don't forget to get the Full Restore to the left before climbing the southern ladder! |
| 5 | The southern ladder will bring you back to the entrance of the cave again, this time use a Pokemon that knows HM Waterfall and ride the waves upward. Go down the ladder you see northwest of the landing point. |
| 6 |
After going down the ladder, you'll see Elite Four Lorelei scolding a bunch of Team Rocket Grunts for taking some Pokemon from Four Island. Help her take them down! After the fight, one of the Grunts will tell you the Pokemon are in the Rocket Warehouse in Five Island. |
| 7 | Exit Icefall Cave by descending the waterfall and go to the Ferry Port of Four Island. From here, choose to go to Six Island first to get the Sapphire needed by Celio. |
| 1 |
To get the other gemstone that Celio mentioned, you have to go to Six Island. Go to the Ferry Port and select that destination when prompted. Be sure to go into the Pokemon Center to have an interaction with your Rival. He will allude that you can get Pokemon from other regions in Six Island that will help with your National Dex! |
|---|---|
| 2 | From the Six Island proper, head east to arrive in Water Path. This route is full of strong trainers with an average Pokemon level of 45 and above. Be sure to be ready! |
| 3 |
From here, head south until you arrive at a rocky area full of Trainers. Follow the road until you arrive in Ruin Valley Be sure to surf south before entering the rocky area to get a Dragon Scale. |
| 4 |
Once in the Ruin Valley, explore the area and catch new Pokemon in the grass. You may also fight Trainers to get more EXP as well. On the southwest part of Ruin Valley, look for an item blocked by two boulders that you can use HM Strength on. Open it up to get an HP Up. In addition, head north to the ledge to see an item near a Hiker Trainer. Open the boulders blocking the way to get a Full Restore. |
| 5 |
From there, continue southeast and follow the winding road until you get to a cave barred by a steel door. Interact with it and you'll see texts written in Braille that translates to the word "CUT". Use a Pokemon that knows the HM Cut to open the door! |
| 6 |
After entering the cave, drop down the hole to start your descent. From here, you will be greeted with a central stone that has more Braille texts that you have to read and follow. 1. UP - drop down the northern hole. 2. LEFT - drop down the left hole. 3. RIGHT - drop down the right hole. 4. DOWN - drop down the southern hole. |
| 7 |
After going down all four correct holes, you will see the Sapphire in the middle of the room. A Trainer will then fall down the hole and take the Sapphire while saying that he will sell it to Team Rocket and will even give you one of the passwords to the Team Rocket Warehouse, "Yes, nah, CHANSEY". You may also read the stone north of the room that reads: "Let the two glittering stones one in red one in blue connect the past. Two friends sharing power open a window to a new world that glows. The next world waits for you." |
| 3 |
Climb up the ladder and exit the cave. Be sure to check the southeast part of the island to get a Sun Stone blocked by a bunch of boulders. Afterwards, fly back to the Six Island proper to ride the Ferry again and go to Five Island for the Team Rocket Warehouse, to get the stolen Pokemon and gemstone once and for all! |
| 1 |
Upon arriving, head east until you reach Five Isle Meadow. This route is going to be full of Team Rocket Grunts, which means you are on the right track to the warehouse. To the right as soon as you enter the area, be sure to use HM Cut to open a path to a Max Potion. |
|---|---|
| 2 |
Continue following the path and use Surf on the eastern part of the path. Cross the body of water to get to Memorial Pillar. Continue following the grassy parts until you reach the southern tip and use Surf. Continue south to reach another island with a huge structure in the middle, with a guy next to it. The structure is actually a tomb of the guy's Pokemon, and offering Lemonade while interacting with the tomb will make the guy reward you with TM42 Facade. |
| 3 |
From there, return to Memorial Pillar and cross the body of water again westward to return to Five Isle Meadow. Approach the structure in the middle to access the Team Rocket Warehouse. Get the PP Up near the warehouse by using Surf on the southern waters of Five Isle Meadow. |
| 4 | Interact with the Warehouse Door, and the player will automatically enter the passwords you obtained from Mt. Ember and Dotted Hole. Enter the warehouse as soon as the door opens. |
| 5 |
The Team Rocket warehouse is a labyrinth of zoom pads that you have to navigate to get through. Make sure to try and experiment with the pads to get important items like TM36 Sludge Bomb, and other consumables. The goal is to get to the northeastern part of the room, where you'll need to fight a Team Rocket Admin and the Scientist who stole the Sapphire. ▶ Team Rocket Warehouse Guide |
| 6 | After clearing the Team Rocket Warehouse, go back to One Island and bring the Sapphire to Celio. With the Ruby and Sapphire in Celio's possession, this will allow you to trade Pokemon with the Hoenn games: Ruby, Sapphire, and Emerald. |
After the entire Ruby and Sapphire saga that spanned across four islands, we finally arrive in Seven Island where you can get some rare Unowns and more non-Kanto Pokemon. To access Seven Island, make sure to get Celio's Rainbow Pass from One Island and approach any Ferry Port and choose Seven Island.
| 1 |
Upon arriving, make a U-Turn to the left until you see a brown bridge crossing the water. Continue south to reach the Canyon Entrance. Talk to the purple-haired Trainer on the bridge to have a Pokemon learn Swords Dance. |
|---|---|
| 2 |
Continue down the path and fight Trainers along the way. Beware, though, as their Pokemon are at least Level 50! Follow the path and head southwest until you reach Sevault Canyon. |
| 3 | From here, just continue following the path and fight Trainers along the way. Make sure to pick up a Nugget south of the two trainers down the stairs, southeast of the cave entrance next to the grassy patch. |
| 4 |
Enter that cave entrance and solve the boulder puzzles. Near the entrance, push the boulders and patch all five holes using HM Strength. - First, push the two boulders nearest the entrance into the two southern holes. - Then, push the top-middle boulder to the top-most hole. - Afterwards, push the remaining two top-most boulders to the farthest east and west holes. - Lastly, push the two bottom boulders upwards and push them to the remaining holes. |
| 5 |
From there, exit the cave and continue exploring outside. Continue south past the Nugget, and follow the path until you see a house with a purple roof. You may optionally interact with the man with a Chansey inside. Make sure to pick up the Max Elixir on the southwestern part of the grassy patch. In addition, you should also pick up the item on the elevated area blocked by boulders and rocks to get a King's Rock. |
| 6 | Continue walking south of the house until you are blocked by a body of water. Use Surf and continue east until you see three mini-islands filled with wild Unowns. Try completing the entire alphabet with all the Unowns here! |
After taking on post-game Trainers and capturing more Pokemon, it's time to challenge the Elite Four and the Champion once again!
Players can return to Indigo Plateau to challenge the Elite Four and the Champion again, who are all equipped with National Dex Pokemon with competitive movesets and higher levels. Be sure to bring your A-Game again!
Alternatively, you can also challenge the Trainer Tower found in Seven Island, where it would pit you against Trainers that have the same Pokemon level as your highest level Pokemon. This is a lighter iteration of the Battle Tower where you can use recovery items during and after battles.
We generally don't suggest doing this though, as the rewards are abysmal for the effort you have to go through. Still, it's a good measure to test out your Pokemon teams and strategies you can employ in battles against Trainers of the same level as you.
First all all, try to complete all the Post-Game Activities noted in the section above. This will allow you to increase the locations you can access, allowing you to complete not just the Kanto Pokedex but also the National Dex.
En route to filling the National Pokedex, we suggest completing the Kanto Pokedex first. This is achievable, though you'd need to actually take time to trade Pokemon with friends who has the other version of the game.
FRLG Exclusives and Differences
Completing the National Pokedex is probably the final and most tedious task you'll have to do in Pokemon FRLG. Unfortunately though, you won't be able to complete the National Dex in the Switch version of the game due to the unavailability of the Hoenn games, but do try your best to fill it up!
All Pokemon in FireRed and LeafGreen (FRLG)
To acquire all stars in your Trainer Card, you'd have to finish five activities:
A bunch of new Post Game Pokemon, both Legendary and non-Kantonian Pokemon, are available to capture in the Post Game of Pokemon FireRed and LeafGreen. Try your best to catch them all to complete the National Pokedex!
| Post-Game Pokemon | |
|---|---|
| Johto Legendary Beasts (Roaming) |
Mewtwo (Cerulean Cave) |
| Deoxys (Birth Island) |
Ho-oh and Lugia (Navel Rock) |
| Unown (Tanoby Ruins) |
Non-Kanto Pokemon (Sevii Islands) |
| Legendary Beasts | |
|---|---|
Entei
|
if you chose the starter: |
Suicune
|
if you chose the starter: |
Raikou
|
if you chose the starter: |
The first post-game Pokemon you can get is one of the three Johto Legendary Beasts roaming around freely in Kanto. They will randomly spawn in grass around Kanto, and the beast that will appear in your save file depends on which starter you chose.
The Legendary Beasts will unlock after infiltrating the Team Rocket Warehouse in Five Island while trying to get both the Ruby and Sapphire.
The bug where roaming Legendaries could permanently disappear after using Roar has been fixed in the Nintendo Switch port of the game, so players no longer have to be wary when encountering them!
Mewtwo is probably one of the most popular Pokemon in the Pokemon universe, and can be fought and captured inside Cerulean Cave, north of Cerulean City. This cave is off-limits before becoming Pokemon Champion, and can only be accessed in the post-game.
Note that Mewtwo is a formidable Pokemon to encounter, having a base level of 70 when you encounter it. Make sure to bring lots of Ultra Balls and bring Pokemon that can paralyze it to make catching it easier!
In the GBA version of FireRed and LeafGreen, the AuroraTicket that allows you to go to Birth Island and catch Deoxys, is locked behind a distribution. In the Switch Version, it will automatically appear in your Key Items after beating the Elite 4 and the Pokemon Champion.
With the AuroraTicket in tow, go to One Island and talk to Celio to progress the process of going to Birth Island. Note that you'll have to give him the Ruby first before you can go to Birth Island from any Ferry Port.
| Deoxys Forms | |
|---|---|
Deoxys (Attack Form) |
Appears if you're playing Pokemon FireRed |
Deoxys (Defense Form) |
Appears if you're playing Pokemon LeafGreen |
Once in Birth Island, interact with the triangle-shaped object until it lands in the center of the island. Save your game, and initiate the battle with Deoxys! Note that you'll be encountering different Deoxys forms based on what version you're playing: Attack Form for FireRed and Defense Form for LeafGreen.
Like AuroraTicket above, the MysticTicket that allows you to go to Navel Rock will be in your Key Items. To actually use it, you'll have to go to Celio and get the Ruby first to unlock Navel Rock as a destination in any Ferry Port.
Ho-Oh can be encountered by going left on the T-junction of the Navel Rock cave. This allows you to climb up to the top of Navel Rock via multiple ladders and encounter Ho-Oh.
The order in which you choose to encounter both Pokemon does not matter, as you can go to the other one afterwards and catch them both.
From the same T-junction of the Navel Rock cave, go right instead. This allows you to descend via multiple ladders to the basement of Navel Rock and encounter Lugia.
The order in which you choose to encounter both Pokemon does not matter, as you can go to the other one afterwards and catch them both.
After the entire Ruby and Sapphire saga that spanned across four islands, we finally arrive in Seven Island where you can get some rare Unowns and more non-Kanto Pokemon. To access Seven Island, make sure to get Celio's Rainbow Pass from One Island and approach any Ferry Port and choose Seven Island.
| 1 |

|---|---|
| 2 |
Continue down the path and fight Trainers along the way. Beware, though, as their Pokemon are at least Level 50! Follow the path and head southwest until you reach Sevault Canyon. |
| 3 | From here, just continue following the path and fight Trainers along the way. Make sure to pick up a Nugget south of the two trainers down the stairs, southeast of the cave entrance, next to the grassy patch. |
| 4 |

| 5 |
From there, exit the cave and continue exploring outside. Continue south past the Nugget, and follow the path until you see a house with a purple roof. You may optionally interact with the man with a Chansey inside. Make sure to pick up the Max Elixir in the southwestern part of the grassy patch. In addition, you should also pick up the item on the elevated area blocked by boulders and rocks to get a King's Rock. |
| 6 | Continue walking south of the house until you are blocked by a body of water. Use Surf and continue east until you see three mini-islands filled with wild Unowns. Try completing the entire alphabet with all the Unowns here! |
To help you complete the National Pokedex, more non-Kanto Pokemon can spawn in the new Sevii Islands (Five, Six, and Seven Islands).
Do note that some of the Non-Kanto Pokemon here are unobtainable due to the unavailability of the Hoenn games for the Switch, but do try to catch as much as you can from the list!
