While Let's Go! Pikachu and Eeevee are hotly anticipated, a surprise from Poke-years past has resurfaced.
The Demo for Gen 2, Pokemon Gold and Silver, was only playable at Space World, Nintendo's own trade show, in 1997.
Now...somehow...it's leaked! And with it comes a variety on the creatures we know and love, including -
Weirdos -



(Part of the Ditto line, Sloking's shell, and Hitmontop)


Unused cursed-panda puppet line.
The Legendary Dogs looking like DeviantArt OCs



Raikou, Entei, Suicuine
Raikou looks kind of like Midday Lycanroc.
Lots of baby'mon.





Meowth, Growlith, Gloom, Mr. Mime, Clefairy
The latter two would grow to be Mime Jr. and Cleffa.
Check out more on the proto page of the Unused Mon here (scroll to demo), on The Cutting Room Floor.
Maybe one day we'll see that Sonic the Hedgehog and MOTHER 3 demo?
