See when it comes to "holding a sword is a new Digimon", they should just have the Star Sword as an attack for Shoutmon and X3 (to cover "Shoutmon + Star Sword, cuz that has a DRB entry lmao) and MadLeomon using the Chainsaw when attacking (the vpets actually did this). when its so minor I don't think they should be their own thing. When Shoutmon X4 puts the sword down, does he technically revert back to X3, or is he X4 still? what if he picks it up and puts it down 500 times?
In my personal headcanon, ShoutmonX4 have a magnetic (psychokinetic?) link to the Star Sword (same with Shoutmon+Star Sword..... though there being profiles for Shoutmon with every piece of equipment under the sun is another topic entirely). It would make sense, considering the Starmons were also involved in the same DigiXros process, technically making them a part of the same Digimon. So basically, he's Luke using the force to grab his light sabre (and that comparison is honestly coincidental and totally not because May the 4th was just yesterday).
there are some scrapped Digimon I definitely want to see like the scrapped enemy trio from V-tamer, all of the odd Pandamons from Digimon Legendary Skies, Technodramon, the Bemmon lone without a doubt, and especially Yo!Yo!Mon who the Digimon Twitter made artwork for recently so it's on Bandai's radar but then there's Digimon I cannot justify the existence of like Mach Leomon who is just Mad Leomon who prefers daggers as a weapon (although Mush-Upped Mach Leomon is good as I like mushroom boys) and Luminamon Nene Version and Shademon Nene Version who make me infinitely uncomfortable and should have never been designed how they are
Are the Nene fusions uncomfortable because naked loli, or because it comes dangerously close to counting a human character as a Digimon (or both)?
Really, though, Digimon Frontier was iffy enough, but at least those Digimon designs were pretty easy to adapt to the rest of the franchise since they're really more of a Digimon-derived Spirit possessing some kind of base, be it human or another Digimon (and hell, whatever human features are there, such as Wolfmon's visible skin, doesn't even resemble the children's physique at all, essentially making the designs 100% Digimon). But if a Nene fusion were to pop up as a raisable "Digimon" in some future media, that'd be awkward as fuck since you'd pretty much just be raising Nene, wearing a Digimon as clothes.
MachLeomon might be workable, though it would help if a colored appearance managed to differentiate it more from MadLeomon. But really, the only Xros Wars design I wanna see dismissed entirely (if you don't count the Nene fusions as Digimon) is that horrible insult to Huanglongmon. I can't express enough how much I despise that moment when the anime, not already content with playing so loosely with the level system we've all grown familiar with, just outright spits on the wider Digimon lore (though I gotta say,
Dorbickmon's final form isn't so bad, as it only looks like a souped-up version of Dorbickmon himself and fits in with most of the other Death Generals having a Darkness Mode). Can't really say I like
HiMugendramon much either (it was obviously a poor attempt at recreating Chaosdramon back when they were still trying to dodge the acknowledgement of evolution in Xros Wars).
Most the other Xros Wars designs, I don't mind one way or the other. I mean, I could live without something like
Appolomon Whispered,
DarkKnightmon's short-lived Baguramon fusion,
SkullKnightmon Naginata Mode,
Mervamon Wide Hi-Vision Sword, pretty much any of the Xros Ups, the variety of manga-only fusions that even Wikimon has trouble securing a decent picture of (aside from X6..... let's get the Shoutmon series completed), or even the actually pretty awesome
SuperDarkKnightmon ever being recognized again, though I wouldn't complain if they did happen to pop up at some point (oh, but do give us
BalliBastemon XD).
