Curious, do we know what 2 were cut?
1st one is most famous one, Weregarurumon. Digivolution item specifically mentions If it had been finished, this would have been his debut in series. I think he would have been treated as Ver 0 Digimon like others who debuted in that game. Strangely, apparently Wikimon has a lot of his requirements and other data. I dont know if its false info, but it sounds possible it was hidden in data. To quote them:
” Were Garurumon is a Digimon that was removed from the game. It has no appearance and has a slighty different name in Japanese, ウェアガルルモン. It is intended to evolve naturally from Garurumon, Leomon, Yukidarumon, or Mojyamon with at least 30 g Weight, 4000 HP, 400 for Defense, Speed, and Brains, and 3 or less care mistakes. Its Finishing Technique appears to be Glacial Blast, the only Technique that was removed from the game. Despite this, there is an unobtainable evolution item to evolve any Adult Digimon into Were Garurumon known as Moonlight Mirror (月光の鏡 Gekkō no Kagami).”
Next one is odd. Its a digivolution item that digivolves to… Kaminarimon. You may wonder who is that? Common theory is that it was Thunderballmon, but Wikimon has conflicting info. Wikimon suggests that its an unsed digivolution item for Kunemon, that was scrapped for some reason. The item was called, Electric Ring, which does fit Kunemon, who has a black electric ring mark on his body. But the item is located within in middle of other Champion digimon digivolution items.
EDIT: Metaletemon, Panjyamon and Gigadramon are super strange. It was recently discovered that Metaletemon’s digivolution item was actually given away as a price in Japan! So they kinda were like event legendaries in Pokemon? There is no proof that Panjyamon or Gigadramon were released, but atleast Metaletemon was. Strangely all 3 had weird changes. Metaletemon was Vaccine, and others were Data, all of them conflicting data nowadays.
