If I can ask, where can I find the "DIGIMON TAMERS COSTUME SHOW AT YOKOHAMA DREAMLAND" in the net or at least a better image of "Kurokomon"?
Also, some Digimon that I know that don't appear and others that I recommend to include:
Blue Nyaromon and Pink YukimiBotamon from D-project. Also like the Black AeroVdramon, there was a Purple Whalemon
In the battle games like battle spirits, when a person choice a Digimon and the other the same Digimon, the second person gets a recolor version, like a silver renamon for example
In the Xros Wars ep 23, there was also a Chick Karatenmon
In the Xros wars manga omake, there is two Digimon inspired by a character of another manga of the author, Hannahmon and KingHannahmon (also a xros of Hannahmon and Mervamon). Also, there is some curious design, like a bancho version of Cutemon
In Xros wars ep 54, when the Digimon is coming back to the digital world in the minute 21, there is a Mermaimon with incorrect colors
In new century, there is a "LordBakemon" as a different Digimon from the regular Bakemon
In Digimon Accel, there is a lot of Digimon that have a Blast Mode that never appear again, so they only remain as sprites
Between all the appmon infected with L-virus, the one that I recommend to include Rebootmon (Virus), that has a lot of relevance in a game
I recommend also include the golden version of Appmon part of Dantemon
In "DIGIMON ADVENTURE TRI. -THE AUGUST 1ST ADVENTURE-" there also four Etemon of other colors, that, including the original one, are called "etemon five"
In appmon manga, there the Appmon Kami of the protagonists get a power up with Minerva Power. Also, a true form of Minerva like the Leviathan's one
In twitter, in a concept art, there was a discarded digimon called "Gryphmon" https://twitter.com/bandai_digimon/status/961435254031437824
Another discarded one from frontier https://x.com/digimonweb_net/status/1110017853745319936
I should include Leo from V-tamer with the same trait as Zeromaru and Gabou, because he also got a card in the original tcg with his name and not just as a regular Leomon https://wikimon.net/Leo
Green Hangyomon https://x.com/RavelMonte/status/2056167904131907656
In this art of the original designs of Digimon, there was only one art that don't end in the final product, the girl https://x.com/JP_Excelsior/status/1254221628952674305
The Chronomon Robot from TS
And a lot of spoof Digimon: Snowballmon, Snowmanmon, petalalamon, the Angela Anaconda ones, the joke xros of hunters https://digimon.fandom.com/wiki/Category:Spoof_Digimon_species
Shoutmon X10 and Sakuradamon from the Xros Wars anniversary
Rokusho, Metabee, Tinpets and medals because Digimon ReArise and the VB
If I can say about Medarot, Mugendraborg, Apocaly The End, Magna Knights, Imperia Drago, Beelzebu Satan, Duke Night and a Metabee with skin of Gomamon
The unofficial KojiAngemon made by Volcano Ota https://x.com/JP_Excelsior/status/1249885213985046532?s=20
In a official MOBA, WarGreymon is a character and have two skins https://300heroes.fandom.com/wiki/WarGreymon

I hope this help. And yes, I am also a nerd of Digimon, I even know some conctest ones that didn't win but were mentioned in magazines like BanchoOgremon if you are interest about that
