Pokémon FireRed and LeafGreen/The Elite Four

'''The Elite Four are, technically, the last bosses of the game. Defeat them and you'll become the champion. However, you need to prepare well if you want to win.'''

Indigo Plateau
Your Pokémon should all be, at the very least, at level 45. The simplest possible team that can win the tournament comprises four Pokémon: one Fire, one Water, one Ice and one Electric type. A Water-Ice dual Pokémon, namely, will decisively reduce your workload.

If you want, you can come prepared with several Revives, Full Restores and Full Heals sold at the counter right at the entrance. Consider also making a trip to Celadon City for drinks such as Fresh Water, Soda Pop and Lemonade, as they are cheaper. Finally, if your Pokémon's moves get low on PP, you could use those Ethers or Elixirs that you've found along your path. However, you won't ever find or obtain any more of them, as they are not sold anywhere.

When you are ready, save your game and walk through the door. Lorelei awaits you!

Lorelei
Lorelei shouldn't give you much trouble if you have Electric Pokémon, as most of her Pokémon are Water types. She begins with Dewgong, which will use to block status problems for five turns and  to pelt your team with hail for five turns. Dewgong also knows and  which are both powerful moves and Ice Beam can freeze your Pokémon, although this is unlikely as the chances are only ten percent. An Electric type is the best choice here, although a Grass type can work, for as long as it's strong enough to take an Ice Beam move.

Cloyster is the most defensive of Lorelei's Pokémon, using to block attacks while slowly weakening your Pokémon with Hail, not too effectively. It also has, so switching Pokémon will result in any Pokémon that cannot Fly or Levitate getting hurt by the trap. Cloyster also knows to dodge attacks and strike on the next turn. Due to its high Defense, Special Attacks are best used against it.

Slowbro is the only member of Lorelei's team that is not an Ice type but it does have Ice Beam nevertheless. Slowbro also knows Surf and has, which will put your Pokémon to sleep on the turn after it is used. Slowbro has high Defense, although not as high as Cloyster, and also has to raise its Special Defense by two levels each time per use.

Jynx is the only member of Lorelei's team that is not a Water type. Since is, in this generation, a Special Attack, Jynx can hit quite hard with that move, but its preferred strategy is to cause Sleep with  or, against male Pokémon, infatuation with its. is hardly worth mentioning because it's such a weak move.

Lapras is Lorelei's strongest Pokémon and is not only bulky but is also holding a Sitrus Berry to restore health. Lapras has a brilliant moveset consisting of, , Ice Beam and Surf. Confuse Ray is especially annoying because there is a 50% chance that your Pokémon will hurt themselves, and Body Slam has a 30% chance of paralysis to make things even harder.

Bruno
Bruno's main type is Fighting, so bring in your strongest Flying or Psychic types for him. On the other hand, he has two Onix to counter any Flying type, so bring in your best Water or Grass type for them. He begins with the lower-leveled Onix, who uses to hurt your Pokémon and lower their Speed;  is still a powerful move as ever; and, which might also lower your Pokémon's Defense. This Onix also has to scare off your Pokémon, but if you are using a Water or Grass type, it is unlikely that he will get a chance to use it.

The second Onix is slightly stronger and can actually make use of its ability through, a very strong Normal attack which would normally cause recoil damage. While Bruno's first Onix might scare off your Pokémon, his second might trap them with, meaning that you can't recall your Pokémon until the move wears off. Like the weaker Onix, it also has Earthquake and Iron Tail.

Bruno's Hitmonchan can hit a Pokémon that uses Fly with. It also uses to send Physical Attacks back at the opponent with twice the power, making Psychic types the safest option against it. Hitmonchan also has Rock Tomb, and, which will always strike first.

Hitmonlee has, to make up for the fact that none of its attacks can hurt Ghost types. Its other attacks are, which doubles in power if the user is under a status affliction, and , which breaks any barriers.

Machamp is slow but has two moves to make up for this: Rock Tomb and, to slow down your Pokémon. Machamp also has to increase its already-sky-high Attack power and a reasonable Defense. Its final move is the powerful but fairly inaccurate. Machamp also holds a Sitrus Berry to restore health.

Agatha
Bring in your strongest Psychic type. All of Agatha's Pokémon are weak to the Psychic-type. However three of them are Ghost types which sort of counters that weakness. Her first Gengar is arguably the more powerful one, despite being at a lower level, although her strategy is to frustrate you rather than use raw power. Using, Confuse Ray and is a very irritating combination and the near-unavoidable  makes it even more annoying. A Pokémon with Safeguard can be a life saver against this Gengar.

Haunter has a fairly good moveset. injures Haunter by 1/2 of its HP, but curses your Pokémon so that it loses 1/4 of its HP per turn, and cannot be dispelled until the battle is over. Haunter also has the and  combo, which aside being a strong attack, the HP your Pokémon loses will heal Haunter. Finally, Haunter also has Mean Look, to stop you from switching Pokémon, which makes Curse rather lethal. Fortunately, Haunter is the weakest of Agatha's Pokémon, and a strong special attack should bring it down quickly.

Golbat has Confuse Ray,, and. You'll need to watch out for Poison Fang's side effect as it deals a severe poison damage similar to Toxic.

Arbok is quite powerful and it knows to lower your Pokémon's Defense by two levels, Bite to deal with Psychic types and Iron Tail and  to hit most other Pokémon hard, with Iron Tail having a chance of decreasing Defense even further and Sludge Bomb being able to cause poisoning.

Agatha's second Gengar is not as annoying as the first, but it does have more powerful attacks consisting of and Sludge Bomb. This Gengar also knows Hypnosis and. One might think that Dream Eater would be a better choice of move, but this Gengar has a Sitrus Berry to restore energy.

Lance
Lance starts with Gyarados, a very strong Pokémon that nevertheless has a massive weakness to Electric types due to its Water/Flying type. is its deadliest move, although it requires recharging after it's used. Gyarados also knows which always takes away 40 HP. and Bite are weak but can cause flinching.

Lance's two Dragonair are identical in every way except one of them knows Dragon Rage and the other knows. Their other moves are Hyper Beam, and Safeguard. Safeguard is fairly pointless as they both have the ability to dispel status afflictions, and it can't protect them from Outrage's confusing side effect.

Aerodactyl is very fast and can use Scary Face, just in case you use a Pokémon that's faster. It also has, which has a decent chance to raise its Attack, Defense, Speed, Special Attack and Special Defense all at the same time, and if it does Aerodactyl will be much more of a threat. Its remaining moves are and Hyper Beam.

Dragonite has a massive weakness to Ice types due to its Dragon/Flying type but is still very powerful. Its moveset consists of Outrage, Hyper Beam and Safeguard, like Lance's two Dragonair, and Wing Attack like Aerodactyle. He also has a Sitrus Berry to restore health.

Blue/Rival
If your starter was Bulbasaur

If your starter was Charmander

If your starter was Squirtle

No matter which Pokémon you started with, Blue will always use Pidgeot, Rhydon and Alakazam. Pidgeot is first and prefers to stall and weaken your Pokémon's stats rather than attack with its only damaging move:. It has to lower Accuracy by one level,  to lower Attack by two, and  to blow away Pokémon it doesn't want to fight. Use Electric, Rock, or Ice moves to exploit its weakness.

Rhydon is probably the weakest of Blue's Pokémon and any strong Water or Grass attack (such as Surf) can wipe it out easily. It attempts to make up for an appalling Speed with Rock Tomb, Scary Face and Earthquake. Rydon's Rock Head ability nullifies the damage that Take Down would usually inflict.

Alakazam is Blue's lowest leveled Pokémon but by no means the weakest. Alakazam is very fast and its techniques are quite deadly. can decimate almost any opponent at this point in the game since you can't get Dark types until after you've beaten the Elite 4. It also has which will strike two turns later,  to restore half of its energy, and  to make up for its appalling Defense.

Gyarados (present if Blue did not choose Squirtle), unlike Lance's, doesn't have Hyper Beam but it doesn't need it. He has Hydro Pump, Bite as well as Dragon Rage, but its deadliest move is. Fortunately for you Thrash will confuse it after two or three turns.

Arcanine (present if Blue did not choose Charmander) likes to use and also has  to deal with faster opponents. Bite is not much of a threat although it will hurt Ghost and Psychic types and can cause flinching. It also has Roar to scare away Pokémon it doesn't like.

Exeggutor (present if Blue did not choose Bulbasaur) will have a massive weakness to Bug types. It knows to increase its Special Defenses. It will also use, , and its signature move.

Blue's Starter Pokémon will always hold a Sitrus Berry. Venusaur may be the weakest one as it is virtually helpless against Fire types, especially since Venusaur will probably use, increasing the power of Fire attacks. However Sunny Day will allow it to use instantly and restore three quarters of its HP through. It will also use to increase its Special Attack by one level.

Charizard manifests a massive weakness to Rock types and an inability to hit them hard. It has to trap and damage your Pokémon, Aerial Ace which is almost impossible to avoid,  which has a good chance of causing a critical hit, and  which will really hurt any Pokémon that doesn't resist it.

Blastoise has enough bulk to hold its own against Electric and Grass types. It has to increase the already considerable power of  and can also use Bite. It is also fond of raising its Defense and then striking hard on the next turn with.

Professor Oak will then take you to the Hall of Fame where you and your Pokémon are honored for their victory. The Professor will then award you the title of "LEAGUE CHAMPION."
