So much to unpack here. So many things that should have been left in. My thoughts:
I loved the water starter's final evo, wish they would have kept it.
Qwilfish's evo, that would have been awesome.
Grotess is awesome and Water/Steel is fun! Wish it would have stayed in.
So Crobat would have evolved from Golbat at lvl 44, interesting.
Baby Paras is adorable!
Animon (Ditto's evo) is such a weird pokemon but I love it. Weird that it evolves from a Metal Coat but isn't a steel type. Also, wonder what the stats are.
Baby Doduo is funny lol
Twins is SO weird but so friggin cool! Dark/Normal is awesome too! Wish it would have stayed in.
Girafarig with both bodies is cool! And Dark/Normal instead of Psychic/Normal is interesting.
Politoad's previous design was awesome! Also, it evolved from something called the Heart stone... weird. (Espeon also evolved from the Heart Stone).
Unown was originally a Normal type.
Slowking/Slowbros' Shells being an actual Pokemon is actually really cool! Water type, would have been fun!
Baby Mr.Mime is so cute!!!
Weepinbell evo that evolves from the Poison Stone. Really cool design!
Kurstraw/Pangshi is cool too! Based on a voodoo doll?
I like Murkrow's original design better.
Scyther wasn't originally a steel type, which makes sense since it was supposed to be in gen 1
Pinsir getting an evo...AH YEAH!
Warwolf is awesome and I want him in!
Original Porygon2 is weird looking.
Likk (Lickitung's evo) is pretty cool looking. Should be a branched evo with Lickilicky
Ho-Oh originally pure Flying?
Leafeon was a thing in gen 2, WOW!
Farfetch'd evo is awesome! Madame!
Poison Stone and Heart Stone were cool. Dragon Scale would have weakened Dragon moves I assume against the user. Kind of cool. Ice Bikini weakens Ice moves, Dragonite would be wearing that Bikini all day long!
Wow, just wow. Some cool stuff they scrapped!
