Pokémon is one of the most well known and beloved video game franchises, and the original 151 Pokémon are considered some of the best designs for characters in any RPG series. But like all projects, the lovable little monsters went through a lot of changes, and some were removed completely.

Early Concepts

Prototype Logo of the original name of the series, Capsule Monsters

Pokémon first saw the light of day as a personal project of Satoshi Tajiri called Capsule Monsters. In this early version of the idea, we can see many Pokémon that were simply redesigned like Rhydon, Slowbro, Gastly, Gengar, Blastoise, Staryu, and Lapras. However, some designs seem to be completely unused. Most of these Pokémon are simple sketches, and may not have been intended to be included in the final game.

  • Papyo - 

    Papyo

    Not much is known about this design, although it looks to be some kind of Bug type. Its Pokédex number is 211 (the number of Qwilfish in the final version).
  • Buhi -

    Buhi

    Again, not much is known about this Pokémon. It is similar in design to Pikachu and Mew, and its Pokédex number is 124, the same as Jynx in the final version. Coincidentally, this is also Caterpie's index number.

(author's note: will work on this more later, feel free to add to this list)

Generation I

The 39 Formatted Pokémon

At a fan convention in 2010, Shigeki Morimoto (the lead programmer of the first Pokémon games) confirmed that there were originally 190 Pokémon intended to be included in the release of the First Generation of Pokémon games. This is backed up by the fact that for the first 190 of the 255 slots in the hex grid of Pokémon, all slots possess either a valid Pokémon, or the same form of Missingno. All 191 slots and later contain garbage data that produce different glitch Pokémon in each slot.

If a certain glitch is performed when trading between the First and Second Generation games, Missingno. will appear in Gold or Silver as a Generation II Pokémon. However, in the same interview, Morimoto also stated that some Pokémon on the hex list in Generation I were not intended for those games (including Ho-Oh). This means that the Pokémon that filled those spaces when they were formatted are completely different from the ones seen in the index list.

A picture of one of the many forms of Missingno.

Interestingly, the original cries for the 39 missing Pokémon remain in-game, although the rest of their data has been removed. Several of their cries are noted to be extremely similar to several Generation II Pokémon cries, further supporting the theory that some of the scrapped Pokémon were recycled for Gold and Silver.

However, in 2019, a leak containing nearly all the unused designs from Generation I surfaced on the internet. Unfortunately, the leaker was unable to recover the front sprites due to the sprites having been updated for Blue, so only the back sprites were recovered. Of all the unused sprites recovered, only 6 were unrecovered entirely (with 2 of them having placeholder back sprites). It should also be noted that, unlike betas for later games, no gameplay footage or stills of the Gen I beta have ever surfaced.

Unused Sprites - Generation I

Number Image Japanese Name English Name Possible Type Notes
21 Omega Same as Japanese ??? Unfortunately, neither of the sprites for this Pokémon were recovered, so we'll never know what this was.
31

Gyaōn ??? Ground/Rock A Pokémon that resembles Godzilla. Possibly reworked into Tyranitar for Generation II.
32
032.png
??? ??? ??? An early back sprite for Nidoran♂. Most likely a placeholder for something else that was removed at the last second.
50
050.png
Barunda ??? Flying A balloon Pokémon first revealed in a biographical manga about Satoshi Tajiri. May have influenced the Drifloon line in Generation IV, as both of the line's members are balloon Pokémon. May have also influenced Jigglypuff, who shares its category.
52
052.png
Bu ??? Ice A yeti-like Pokémon. This was supposed to be the original Ice-type counterpart to Electabuzz & Magmar, and a male counterpart for Jynx. It's possible that it & Jynx were even intended to be version exclusives. Possibly inspired other yeti Pokémon such as Abomasnow from Generation IV and Crabominable from Generation VII. It's also possible that the concept of unevolved gender-specific counterparts used for Bu & Jynx was reused for Tauros & Miltank.
56
056.png
Deer ??? Normal A deer Pokémon first revealed in a biographical manga about Satoshi Tajiri. May have influenced later deer Pokémon such as Stantler from Generation II, Deerling and Sawsbuck from Generation V, and Xerneas from Generation VI.
61
??? ??? Either Normal or Water An elephant Pokémon first revealed in a biographical manga about Satoshi Tajiri. Its name was also shown, but unreadable due to being cut off. May have influenced Phanpy and Donphan from Generation II, as well as Cuphant and Copperajah from Generation VIII.
62
062.png
Crocky Same as Japanese Either Normal or Water A crocodile Pokémon first revealed in a biographical manga about Satoshi Tajiri. Had hair in the manga, which was later replaced with spikes in the beta. May have influenced crocodilian Pokémon such as the Totodile line from Generation II and the Sandile line from Generation V. It also may have influenced Dreepy from Generation VIII.
63
063.png
??? ??? Water A squid Pokémon. May have influenced Inkay from Generation VI and may have possibly been reworked into Omanyte.
67
067.png
Cactus Same as Japanese Ground A cactus Pokémon first revealed in a biographical manga about Satoshi Tajiri. May have influenced Cacnea and Cacturne from Generation III and Maractus from Generation V.
68

80

90.9983x90.9983px

??? ??? Water/Fighting A fish Pokémon and the evolution of 79.
81
081.png
Mikon ??? Fire A pre evolution of Vulpix that was later reused in Generation II.
86
BetaSphere.png
??? ??? Fighting A sumo Pokémon with what appear to be boxing gloves. May have influenced Makuhita from Generation III, as it also has a sumo motif.
87 ??? ??? Fighting A sumo Pokémon and the evolution of 86. May have influenced Hariyama from Generation III, as it also has a sumo motif.
94 ??? ??? Dragon A lizard Pokémon. Somewhat resembles Mew.
95 ??? ??? Dragon A lizard Pokémon and the evolution of 94.
115 ??? ??? ??? Like 21, neither of this Pokémon's sprites were recovered, so we'll never know what it was.
121 ??? ??? ??? Once again, neither of this Pokémon's sprites were recovered. (Perhaps 21, 115, and 121 were related?)
122
122.png
??? ??? Water A squid Pokémon and the evolution of 63. May have influenced Malamar from Generation VI.
128
127.png
Zudakku (possibly) Zuduck (possibly) Water A middle evolution for Psyduck that appears to have elements of both Psyduck and Golduck.
134
134.png
??? ??? ??? Appears to be an early back sprite for Meowth. Like Nidoran♂, this sprite is most likely a placeholder for something that was removed at the last second. The actual front and back sprites for this design were first revealed in a 2004 interview, but were too blurry to be seen clearly. Contrary to popular belief, this is not Konya, the Meowth pre evolution from Generation II, as its back sprite is too large. However, it's possible that Meowth's final back sprite was originally Konya's, because it doesn't match the front sprite very well due to its size and lack of Meowth's forehead coin.
135 ??? ??? ??? Yet another Pokémon whose sprites weren't recovered. Like 134, its actual front and back sprites were first revealed in a 2004 interview, but were too blurry to be seen clearly.
137
137.png
??? ??? ??? A pre evolution of Gyaōn. Like its evolution was based on Godzilla, it may have been based on Minilla (a baby Godzilla) from the 1967 film Son of Godzilla. Possibly reworked into Larvitar for Generation II, like how Gyaōn was presumably reworked into Tyranitar. It also resembles the Substitute doll.
140
140.png
???koiru ??? Electric A middle evolution for Magnemite, as Magneton was created first, while Magnemite was created very late in development. Replaced by Magnezone in Generation IV.
146
146.png
??? ??? Ground A final evolution of Cubone. It appears to be holding a baby Cubone. Its skull strongly resembles the one used in Marowak's later design, first seen in the anime.
156
156.png
Gyopin ??? Water A pre evolution of Goldeen that was later reused in Generation II. Had its own moveset and evolution data.
159 Kotora ??? Electric A tiger Pokémon that was later reused in Generation II. May have influenced Shinx from Generation IV.
160 Raitora ??? Electric A tiger Pokémon and the first evolution of Kotora that was later reused in Generation II. May have influenced Luxio.
161 ???tora ??? Electric A tiger Pokémon and the final evolution of Kotora. Unlike the other members, it wasn't reused in Generation II. May have influenced Luxray from Generation IV.
162

Puchikōn ??? Fire A pre evolution of Ponyta that was later reused in Generation II.
172
172.png
??? ??? Water A pre evolution of Blastoise, who was originally separate from the Squirtle line.
174 ??? ??? Dragon A lizard Pokémon and the pre evolution of 94. Bears a very strong resemblance to Mew.

181

??? ??? Water The original final evolution of Squirtle before Blastoise became part of the line.


Generation II

1997 demo title screen

The second Generation of Pokémon games - Gold & Silver - began development almost immediately after Red, Green, and Blue were finished. Like the first Generation, Generation II also had its share of scrapped designs. There've been 3 leaks containing unused Generation II designs - the first, dated 1997, is from the earliest demo version of the game played at Spaceworld 97, the second, dated 1999, is from the third demo version of the game (which looks closer to the final) at Spaceworld 99, and the third, dated 1998, is from the second demo version of the game. The sprites shown below are from the 1998 beta, but include designs from both the first and second demos. Oddly, the Index Order here starts at 300 instead of the expected 191. Why this is and why slots 191-299 weren't included is unknown.

Number Front Sprite Back Sprite Japanese Name English Name Possible Type Notes

Kokopelli.png

1525b.png
Gurotesu ??? Water A Pokémon resembling an eel/angler and the evolution of 301. Was the final evolution for this line in the 1997 demo.

303
Tumblr inline pk6h46I4cz1tgpnc7 400.jpg
Ikari ??? Water A shark Pokémon with an anchor attached to it and possibly a split evolution of 301. Was the middle evolution for this line in the 1997 demo. Most likely reworked into Sharpedo for Generation III while the anchor may have been reused for Dhelmise in Generation VII.
304
Proto Fennekin.png

306
Oddball2.png

1577b.png
Mizuō Quagsire Water Early Quagsire. Typing is Water/Ground in the final. Doesn't evolve (Wooper wouldn't be introduced until the 1999 beta). Japanese name is Nuō in the final. It's possible that Quagsire making its debut in the anime before Wooper may have been a reference to its being created first.
319
Boardeer.png

327
Beta-83.png
1558b.png
Norowara ??? Ghost A voodoo doll Pokémon and the pre evolution of Kyonpan. May have inspired Banette from Generation III, which is also a Ghost-type doll. The fact that Banette sticks needles into itself further proves this connection.

Its true appearance being hidden by the costume may have inspired Mimikkyu from Generation VII.

Gongu Tyrogue Fighting Early Tyrogue.


This table showcases the sprites from the 1999 demo. There were 2 demos, the second of which was much closer to the final game, so there aren't as many unused designs here. However, there seem to be a lot of swaps and replacements here (i.e., Madaamu being in one version, but getting replaced by Wooper in another version). The first 2 columns showcase the sprites that were in the first demo, while the 2 columns after them showcase the names and types in that demo.
