Doomslayer does have the added bonus of already having a Mii outfit over Master Chief. That shows that Nintendo is open to working with the property.
I think that's a little less promising when you look at how none of the third-party costumes from 4 actually became fighters in Ultimate. In fact, 4 added Virtua Fighter costumes, then Persona got in instead. 4 added SMRPG costume, then we got Dragon Quest.
I mean yes it's good that they weren't like "Doom is too M-rated to even set foot in Smash", but the correlation between costume and character seems pretty weak atm. For third-parties, at least.
The only real hurdle I see for Doomslayer is the amount of gore and violence in DOOM. It’s basically the same issue as Mortal Kombat but to a lesser extent. We did get Bayonetta as a playable character though and that series can be pretty bloody itself so I definitely think they can work around that. Same goes for Mortal Kombat if the lack of presence in Japan isn’t a barrier.
I think a bigger hurdle is that Doom is not big in Japan at all. You can tone down violence, but Smash so far has been explicitly averse to series that resonate in a highly lopsided way. That's what's ultimately going to keep Mortal Kombat out more than the gore.
And no, having a costume in Smash doesn't suddenly mean Japan is big on Doom any more than the west is now all about Goemon and Tower of Druaga. And yes, I'm aware there is a fanbase for Doom in Japan. There is a fanbase in the west for Sakura Wars. Doesn't mean those things aren't still niche as heck.
All good points. I wasn’t trying to argue that Master Chief can’t or shouldn’t get in, just that I think his lack of Nintendo presence would at least be a small factor in the decision.
I mean his lack of Nintendo presence probably would be one of the facets that is weighed in his consideration. It's certainly not his strong suit, and having a Nintendo presence would also help another of his shortcomings, his visibility and presence in Japan. Plus, with Halo game(s) on a Nintendo console, he'd probably be all the more requested for it, and have gained his (genuine) demand much earlier.
It's just that if it really is a factor of more insubstantial weight, his positives would presumably be able to outweigh it. Not that that would necessarily mean he'd get in, just that that wouldn't immediately cut him off at the knees, and he could still be seriously considered, possibly included, despite that.
If he was far and away the number one choice, I think that distinction wouldn’t really matter but he does have an equally iconic competing character that doesn’t have that problem. All things being equal, I feel like they would likely lean towards the character with a stronger Nintendo presence but I could always be wrong.
There is an argument to be had of equality in iconography between Doom and Halo as games (unfortunately for Doom, I think a lot of its advantages, like influence, are less important factors for Smash inclusion). But tbh, with Doom Slayer and Master Chief as characters, the scales are far more unequal. Master Chief is a much more prolific, identifiable presence than Doom Slayer. I mean, Master Chief is the mascot of one of the big three, and has been since their earliest days in gaming.
I don't think there's anyone who would elicit a bigger pop off in Smash at this point (outside Japan). In the west, Master Chief is up there with, like, Sonic and Link. Doom Slayer is by no means a slouch, he's very well known in his own right (despite people being a little mixed on what his name actually is) but... Chief is in a very, very lofty strata of identifiability.
I mean, Doom Slayer didn't start gaining major demand until Doom 2016 came to Switch. Crash didn't start gaining major demand until the N. Sane Trilogy came to Switch. Dante didn't start gaining major demand until his games were getting ported to Switch. Master Chief has his comparable popularity with almost no Nintendo presence to show for it, and had droves memeing about him in Smash as far back as Brawl.
So I don't think all else actually is equal.
