Along with some other Diamond & Pearl beta sprites leaked in 2020, Lumineon's early design was significantly different compared to what it looked like in Gen 4's final build.

Lost Pokemon of the Week:

This bagworm and moth Pokemon were created during Gen 2's development, but didn't make Johto's final cut. More than twenty years after getting scrapped, they were made public when files leaked in April 2020.

Beta Cyndaquil:

When Cyndaquil was created in the middle of Gen 2's development, he wasn't originally meant as Johto's Fire starter. In fact, he doesn't appear to have even been Fire-type.

Beta Gengar:

With a beta sprite dating back to 1990, Gengar was among the earliest Pokemon ever created. What changed in development? Mostly his eyes, ears, teeth, and chonkiness.

Beta Mareep:

In Gold & Silver's 1997 demo, Mareep was originally pink and named Pachimee, which is Japanese for "spark bleat." But he was later changed to yellow and renamed Merriep.

Lost Pokemon of the Week:

Revealed by Game Freak in 2018, this Elephant Pokemon was originally created during Gen 1's development. He ended up getting cut, but a possible reference still exists in the game -- Raichu's Japanese Pokédex entry.

Beta Gastly:

Gastly was created around 1990, but didn't look like the Gastly we know today until around 1995 -- his beta sprite, as well as his Red, Green, & Blue sprites reveal what he USED to look like.

Beta Smoochum:

In Gold & Silver's 1997 demo, Smoochum was originally pure Ice-type and named "Rippu" (which means Lip). But she was later renamed, redesigned, and revised to Ice/Psychic type.

Lost Pokemon of the Week:

Mikon was originally created for Gen 1, but ended up getting cut due to lack of cartridge space. One year later, Mikon returned in Gold & Silver's 1997 demo... but ultimately, got cut from Gen 2 as well.

@_Audinair @SkinnySnubbull Well they're not fossils, but we've already got a mammoth, and those things only went extinct 3700 years ago. At this rate, there'll be human-based Fossil Pokemon a few generations from now lol. Now that I think about it, a Neanderthal Pokemon would actually be pretty awesome.
