I'm actually digging some of these stuffs now.
The water and fire starter line looks like what we once knew in this list of
unused Pokemon design. Kurusu and Honouguma.
However, we knew they never came to appearance. Looks like Cyndaquile-Typlosion's base stats being similar to Charmander-zardon's are due to rushed nature of the game?
Honouguma line is just so pretty though, they can easily rival Fokko/Fennekin line.
And then there's this pretty angelfish which seems to evolve to uhh... anchored shark and whatever else the next one is? Looks like a branch evolution. That anchorshark seems to later inspire Sharpedo and Huntail, the angelfish is scrapped (nuu), and the anglerfish (touche, da pun) is redesigned into Lanturn.
Graceful Arceus, glad they scrapped that beta baby Vulbit-err, pix. But looks like they have planned many other baby mon like that little puppy that could be baby-Gardy/Growlith
?, laying baby Meowth (that seems like holed everyday coin), another Ponyta, baby
? goldfish, baby Mr. Mime (redesigned into Mime jr. later), etc..
Looks like baby Meowth is scrapped because anime once shown Rocket trio's Meowth as baby.
Some seem reused into future designs.
Beta-Noctowl looks close to barn owl that inspires Rowlet and Dartrix.
That kite-bird right before Quilfish
? seems to be redesigned into Mantine. While the scary face looks like it won't work really well in actual battle (due to it not viewable by opponent below). This "scary face" concept is taken by Masquerain later.
Some also diverged like Kamonegi-evo scrapped and reused into Swanna.
Some seemed to be redesigned to tone down the... controversial material.
After Houndoom
?, there's this critter-in-pelt thing, redesigned to Swinub line? Well, the idea of pelt monster is....
And also Octank/Octilerry was literally a tank soldier and Remoraid was literally a barrel/revolver-gun, which was redesigned to suit the demography.
That cursed-doll (Ushi no toki mairi) thing and Kyonshi (chinese zombie) mon was scrapped. At least we got Muuma / Misdreavous to replace them.
And in the end before Unown is what seemed to be a pretty Leafeon. But it's not placed next to Espeon and Umbreon, seemingly designed by others before scrapped and reused by Nishida into actual Leafeon later. While it looking grass seems to inspire Celeby to continue the Mew-clone / mini-mythicals.
And no Lugia. It seems like they didn't plan it being two-version game, being the planned last game to end Pokemon? (thank Arceus they didn't)
Oh, came to read the spreadsheet and... interestingly, beta-Scizor's
Japanese name is
Scizors (close to current English name), before renamed
Hassam.
That pretty Leafeon
is planned to be Leafeon. But it's placement is odd, not with Espeon and Umbreon. It's name リーフィ
Riifi / Leafie is even similar to エーフィ Eifie (Espeon), before later added an "a" into リーフィア Leafia along with グレイシア Glacia (Glaceon). Did Nishida originally designed it?
Thay also removed that Bomshika (that fireball seal). Amusingly, Water/Fire would had been really interesting while we here only have Volcanion to try that.
