I don’t know about that. It was shown in cinemas across the west, I saw it cinemas when I was little, and I'm now their target audience. Plus, with how crazy popular Omegamon is people surely checked out his debut and are thus aware of who Diaboromon is.

Plus, Diaboromon rarely gets figures, let alone articulated ones aimed at collectors. That alone makes him more desirable even for people who don’t care about gimmick figures but want something to face off against their Omegamon figure.

Personally, I think people got tired of the gimmick. It’s just shellformers. Very well done shellformers but still. A new release every two months was pushing it too hard, there were multiple future pre-order popping up before the first figure was even out.

Maybe they should just try plain old Figuarts next time. Something beyond the first three seasons for a change. I think the H Spirits would be awesome as SHF's. Just make Agunimon and Lobomon and see if they sell.

The original movie was that bad ?

It was great. The stupid pop-rock dub kinda ruined it but as a kid I didn’t care.

And if you liked the concept but could never get into Digimon there's Summer Wars.

there's a few of epic songs in 2000 and 2001 in this film.

Omegamon, one of the most popular Digimon in the franchise.
And apparently no one saw his movie. Either Digimon the Movie or Our War Game, apparently.

I find it a little hard to believe.

I saw the Digimon: The Movie when it came out in theathers twice to get all of the cards. I saw the first time with my dad, and my sisters on the opening weekend. The second time with my friends and we end up seeing Book of Shadows: Blair Witch 2 afterwards.

The original Japanese versions of the movie are not too bad for what they are. I saw Digimon: Adventure Our War Game like nearly a year later on a bootleg VHS tape with iffy subs (There was hardly anyon who subbed Digimon at the time). The dub fused three movies into one and try to link each other. The dub has a so-bad its good vibe to it in my opinion.

The soundtrack for that movie was pretty much any major song on the mainstream raido in 1999 and 2000. I'm surprise music from Creed and didn't show up in the movie. It was somewhat common for animated movies for kids to have rock and music soundtracks. The dub for DBZ Movie 4 & 5 (Lord Slug and Cooler's Revenge) also had popular music in their soundtrack. I also remember the Pokemon movie having a pop music soundtrack.

That's funny, the movie came out here in Brazil direct-to-video in VHS.

Unless you are a newer fan then you know who Diablomon is. Hell even the design itself should help sell the toy.

Digimon: The Movie I believe only got a domestic release. It made over 16 million, on a 5 million budget. That's a modest success but indicates a small viewership. I was a big Digimon fan as a kid, still am, but I never saw Digimon: The Movie in theaters and most of my friends did not as well. We weren't aware of Omimon/Omegamon until he was referenced in Adventure 02. So super die hard fans that saw everything and then some probably saw this film and the Japanese versions if they had the means to. More passive fans probably aren't that aware of Diabolomon. They may recognize it at a glance but it's not a figure they have ties to or desire to own unlike the classic characters from the tv series.

So my whole point was perhaps the mainstream fandom was exposed to Diabolomon at some point with the tv airing of Digimon: The Movie (most likely didn't see it in theaters), but have no attachment to it like they do the eight digimon that belong to the core digidestines. Diabolomon should follow an Omegamon/Omnimon figure.
