Guide to Underleveled Pokemon
Updated automatically every 5 minutes

Intro

This guide is meant to serve as a resource to finding and catching every possible underleveled pokemon. An underleveled pokemon is a pokemon that can be caught at a lower level than it evolves naturally. Some of these pokemon are quite easy to find, others are quite difficult and rival shiny hunting. This guide contains only the locations for the most underleveled pokemon available. For example the locations of a level 3 metapod are included but a level 4 is not. For this list, I consider pokemon that evolve when knowing a specific move, like Tangrowth and Tsareena, underleveled if they can be obtained at a lower level than their pre-evolution naturally learns the move. In the case of event-only underleveled pokemon, I list both the lowest event and non-event level. This list only includes pokemon that can be obtained through normal gameplay using intended game mechanics. This list excludes pokemon obtained in pokemon go. This is because virtually every pokemon can be obtained at level 1, sucking a lot of fun out of the challenge. Also the availability of certain pokemon in pokemon go can vary wildly in different parts of the world and based on what Niantic events are active which can make it frustrating for most players. If you notice an error, omission, or have a suggestion, please don’t hesitate to message me at reddit.com/u/pikmin34

Last Updated: November 13th 2024. Fixed error in Marowak entry. Spewpa added. Staraptor added. Strat to obtain Crobat at level 10 using PLA for evolution. New strategy added to get kingambit at level 21 instead. Fixed minor errors and clarified certain entries.

Encounter Tables and Slots

Before continuing it is important to understand encounter tables and slots. Every pokemon game has what is essentially a large list, called the encounter table, that stores the location, rarity, and level data for each wild pokemon. When a wild pokemon is to be generated, the game generates a random number and looks at the encounter table. Based on that number, the game looks at a particular entry in the table, known as an encounter slot, and generates a pokemon that corresponds to that random number. Depending on the information in the table, the rarity of pokemon at a specific level may be better or worse than simply dividing the aggregate chance to encounter that species by the total level range.

This is probably best explained with an example. Let’s say we want to get the level 25 Magcargo in FRLG. Most resources will say that Magcargo has a 10% chance over levels 25 to 45 to spawn in a rock smash rock in Mt Ember BF3. If we simply divide 10% by the 21 level range that gives us a 0.476% or roughly 1/200 chance to find the magcargo we want which is low but not terrible. Sadly, if we look at the encounter tables it's much more bleak than that. The encounter table for rock smash in Mt Ember BF3 looks like this.

Area

Slot 0 - 60%

Slot 1 - 30%

Slot 2 - 5%

Slot 3 - 4%

Slot 4 - 1%

Mt. Ember Ruby Path B3F

SLUGMA

15-25

SLUGMA 25-35        

MAGCARGO 40-45        

MAGCARGO

35-45        

MAGCARGO        

25-35

The Magcargo we want is in slot 4, which only has a 1% chance. We need to then divide this by the 11 range to give the actual chance of finding our magcargo. 1%/11=0.0909% of 1/1100. This unfortunately means well spend a long time searching and glaring at the level 40-45 magcargo constantly teasing us. In BDSP, a level 16 Magcargo is available which makes this hunt easier.

There are some times where this helps us too. Here’s an excerpt from the RB viridian forest table

Pikachu 5

If we want to catch the level 3 pikachu we’ll need for electrode. Our odds are 4% which is better than the 2.5% we would see if both levels were evenly distributed.

                

Gen I and II

The most notable feature in generations one and two is using in game trades and cross generational trading to get low level pokemon. Pokemon received from an in-game trade always have a level that matches the pokemon traded away, which allows for some very underleveled pokemon especially when the pokemon traded away is bred in generation 2. Nearly every pokemon caught in the wild in GS is also available in HGSS with similar encounter rates, so if you are picky about balls it’s best to hold off on these pokemon.

Gen III

There are no underleveled pokemon that need to be obtained in generation three. The only potential exceptions are Magmar and Electabuzz which were available as level 10 event pokemon which are unfortunately no longer available legitimately.

Gen IV

This generation four’s most notable feature is the pokeradar. There are several pokemon that can only be obtained in this way. When hunting for them, make sure to only look in patches shaking grass with white lines. HGSS contains most of this gen’s target pokemon although many are shared with gen 2

Gen V

Generation five features specific patches of grass or water that shake and have a unique sound effect when active. Entering or fishing in these spots has a chance of spawning rare pokemon, many of which are underleveled. Using the local multiplayer feature entralink in B2W2 allows you to unlock Pass powers which can be used to make rare pokemon more common and special spots more common. Due to this, it is best to hunt special spot pokemon in B2W2 whenever possible. B2W2 also feature hidden grottoes which have a rare chance to spawn some underleveled pokemon. This generation features what I consider to be the crown jewel of underleveled hunting, the level 1 Gyarados.

Gen VI

In XY, only hariyama is caught naturally. All the rest of the underleveled pokemon for these games are caught in the friend safari. The friend safari is accessible after beating the elite 4. The type and species of pokemon available in a safari are determined the friend’s you have added. In a specific friend’s safari, the first two pokemon are available immediately after adding the friend even if they don’t own pokemon X or Y. The third slot only becomes available by being online at the same time as the friend. In order to find a specific pokemon, it is best to add a friend at a community such as reddit.com/r/friendsafari.

In ORAS, the white flute is needed for the most underleveled pokemon. When played it reduces the level of all wild pokemon by up to 4 levels. It can be obtained from the glass workshop on route 113

Gen VII

Generation seven is by far the most aggravating generation in my opinion. The first issue is SOS battles. SOS battles are a unique mechanic in this gen which enables a wild pokemon to call for help which can occasionally be the next pokemon up in the evolutionary line but at a low level. However, this feature is very tedious and is marked by low spawn rates and huge level ranges for some pokemon. Using an adrenaline orb will increase the spawn rates but it is still quite frustrating. The other issue is pokepelago exclusives. Kadabra and Drifloon in SM and Flaaffy in USUM will rarely appear in isle abeens and can be recruited to your party. However these pokemon have a fairly low rate of appearing in the first place. Once they appear they need to decide to stay in your party but this can be soft reset for. Once they join you, There’s a 7 level range of availability which makes the proper, level 11 pokemon even rarer. On top of this they are only available before beating the second island so for most people will require a new playthrough. Also, the appearances are tied to the real time clock, so you can’t just adjust the 3DS time to spawn new pokemon. Without the use of custom firmware and a real time clock editor. It may take several months or even years of trying.

In LGPE most of your time will be spent looking for pokemon flying in the sky. If you set charizard, dragonite or aerodactyl as your following pokemon, you can fly and encounter flying pokemon from levels 3-56. Fearow, pidgeotto, pidgeot, dragonite, and charizard are all obtainable at level 3 as well as the legendary birds, but they are not considered underleveled.

Gen VIII

        With the exception of diggersby and ninjask, every single underleveled pokemon here is found in a raid. 2 switches and two copies of the game will be required. The first switch needs to progress to the end of the game, or at least until 5 star raids are available. The second switch needs to just reach the wild area but not collect any badges. Switch 1 should use a wishing piece to generate the desired den. If the species is not the desired species, inviting others to the raid, advancing the date on the switch by one, returning to the game, and backing out of the den menu will generate a new pokemon in that den. Switch 1 should host the desired raid and switch 2 should join it. Once the raid is defeated, catch the pokemon on switch 2 and it will be at level 20 due to the level cap of wild pokemon being 20 for badgeless players. There are well over 100 pokemon available this way. Note that the dens I have listed are absolutely not exhaustive, but they do represent dens with the best chance of finding that particular species. If going for a full set, it’s best to go for dens with multiple species you want to maximize efficiency.

        BDSP has a fair amount of new underleveled pokemon despite being a ”faithful remake” of gen 4. Most of the standard encounters are the same as the games they are based on, but the pokeradar and grand underground hold some new targets. In particular obtaining the national dex after getting the first badge unlocks all pokemon in the grand underground, even those that normally require certain point to be reached in the main story. To get it you must at least see all pokemon in the sinnoh dex, which can be done using trades or pokemon home. Then make sure you have visited Eterna City. Finally, talk to professor Rowan in his lab in Sandgem Town to receive the national pokedex.

        In PLA, Gamefreak took a good amount of care in making sure the levels of wild pokemon exceeded the evolution thresholds. There is a level 49 Hisuian Braviary in Alabaster Icelands and a level 31 Staraptor in the Cobalt Costlands. Apart from that, the only underleveled pokemon are silcoon and cascoon, but these are still outclassed by ORAS so there’s nothing else to hunt in this game. However, a level 25 Ursaluna is possible by bringing up an ursaring from crystal. One important detail of note is that many pokemon that have evolutions triggered by level up after a condition is met (ie. friendship) can be evolved by pressing x rather than level up once that condition is fulfilled.

Gen IX

One would think gen 9’s open world would lead to many opportunities for underleveled pokemon but, only three exist in the overworld (spewpa, donphan, girafaiai). A level 21 kingambit can also be obtained by use of pokemon home by catching a level 20 in swsh and fulfilling it’s evolution requirements in SV.

Encounter rates

Encounter rates in the table below refer to the actual chance of finding the underleveled pokemon taking into account both the rarity of the encounter slot and the level range. It is not simply the odds of encountering that species. In many cases, these rates can be somewhat convoluted and represent my best knowledge with the information I have available. For pokemon that appear in multiple places in a game, the place with the best rate is listed. In raid dens, the odds are the odds assuming the host has an end game save with access to 3-5 star dens and the den with the best chance is listed

Difficulty

Difficulty is somewhat subjective but the rankings are based loosely around the following criteria. The difficulty is also ranked as if you were playing as a purist. Obviously using RNG manipulation or external tools to alter the games’ state can make obtaining these pokemon much easier.

*  - Very easy. Encounter rate 10% or greater. No setup other than reaching that part of the game. Can often be found in a matter of minutes.
** - Easy. Encounter rate 3-10% or may need minimal setup. Time to encounter may be in the range of 10 minutes.

*** - Moderate. Encounter rate 1-3% or may need some setup. Will probably take around a half hour to find your target

**** - Hard. Encounter rate between 1 and 0.2% or a difficult setup. May take hours to find your target

***** - Very hard. Encounter rate is 0.2% or less or the setup to encounter it is excruciating. May take many hours or even days to find your target

Charizard

LGPE

****

Flying in the sky. Many routes Level range 3-56. Charizard is a special spawn. The best way to find it is to start catching a lot of pidgey in a chain. As your chain increases the odds of encountering a charizard also increase until you reach a max chain of 31. At this point, spawns will be very frequent. When a charizard spawns, if it is not the level you want, just run away. This will not break your chain. Do not use lures as this caps all spawns at level 57.

SM

*****

The level 11 kadabra is found as a visiting pokemon on isle abeens in pokepelago. It can only be found on a save that has reached akala island but not beaten the grand trial on akala yet. Upgrading to level 3 is recommended as it enables more pokemon to visit at once. A visiting pokemon has a 0.64% chance to be a level 11 kadabra. What makes this so excruciating is that you must wait a long time to get it to appear since you cannot just advance the clock on your 3ds.It will likely take several months of checking to get the pokemon you want.

It will evolve after the trade into a level 5 machamp. It is important to note here that trade evolutions cannot be canceled. This is important because of the implications it has on other in game trades. If the evolution could be canceled, the level 5 machoke could be further traded to obtain a level 5 haunter, gengar, and xatu in the japanese games.

B2W2

******

The Holy Grail of underleveled pokemon. It is found in the nature preserve which is difficult to access on its own as it requires seeing every pokemon in the unova dex. Once there, gyarados can only be found by fishing in a bubble spot which takes some time to generate. The level 1 gyrados can only be found in the 1% encounter slot. The level range in this slot is 1-100. This means that the overall odds are 0.01% or 1/10,000. Fortunately,pass powers will help you out Lucky Power S will make the bubble spots spawn much faster. Exploring power S will boost the odds of the 1% slot to 20% so your odds will be 0.2% or 1/500. That being said, it’s still a huge undertaking. Good Luck

Drifblim

11

SM

*****

The level 11 Drifblim is found as a visiting pokemon on isle abeens in pokepelago. It can only be found on a save that has reached akala island but not beaten the grand trial on akala yet. Upgrading to level 3 is recommended as it enables more pokemon to visit at once. A visiting pokemon has a 0.64% chance to be a level 11 drifblim. What makes this so excruciating is that you must wait a long time to get it to appear since you cannot just advance the clock on your 3ds.It will likely take several months of checking to get the pokemon you want.

Kingambit

21

SwSh+SV

*****

Significant setup is required to obtain a kingambit at the lowest possible level. First obtain a level 20 bisharp from SwSH and transfer it to Home. Next transfer it to a SV and teach it steel beam and have it hold a leaders crest. Head towards the bamboo forest near north province area two (This is possible even without upgrading your ride pokemon). Find a wild bisharp surrounded by wild pawniard and defeat it using the level 20 bisharp using steel beams recoil to knock both the wild bisharp and your bisharp out at the same time so no experience points are gained.
