I'm someone that isn't a huge fan of playing all the fighting games, but I love watching a lot of them and I love when characters from different properties join the fray and create fun potential as crossovers. Akuma in Tekken, Cloud in Smash, 2B in Soul Calibur, Halo Spartan in Dead or Alive, these tend to add some fresh new possibilities to games and I thought it could be fun to talk about characters we would love to show up in current or upcoming fighting games.
Smash Bros Ultimate
Sub-Zero - In the fighting game scene, Mortal Kombat has a long of a history and with Mortal Kombat returning to Nintendo with MK11 this year, I think the blue frosty ninja is a great pick and possibly a an easier choice compared to having Scorpion show up. His design would be very traditional, much like we saw of Scorpion in the new trailer, but he would have his new MK11 design, and the rest of his looks would just be the different classic ninja colors like Ermac, Smoke, Scoprion, Reptile, etc...The only possibility of this not happening would be due to every character having Japanese origins, the only possible outlier being K.Rool, but that was still a Nintendo property.
Banjo-Kazooie - This is literally my most wanted characters. I've always been a huge fan of the games, the first game being an all-time favorite, and with their history on the Nintendo 64, I think they are an important choice. They also aren't of Japanese origin and aren't something Nintendo owns, but I think this is the biggest addition they could have to the game and they have been a big hope by a lot of people.
Monster Hunter - We got a Rathalos, so why not put in a hunter from the game? It's a massively popular Japanese property that got a popular new entry, and it's a character that they've made work in Marvel vs Capcom: Infinite, so just bring that over. The character can be male or female like Robin and could have a few different armor sets and weapons based on the gear. A traditional Rathalos armor and whatever else is considered iconic for the series.
Mortal Kombat 11
Doom Slayer - I've seen people say they'd love to have Doom Guy or "Doom Slayer" as he is known now in Smash and I personally think that's a complete waste. For a game known for its brutality that only hit new levels with the reboot of the series, I can't think of a better game for Doom Slayer to show up in. The only problem could be his projectiles with guns, as that's been shown to be an issue in NetherRealm games in the Injustice series, but I think they could tone that down now due to him in the new game having a sword and maybe keeping his projectiles a little more close range like his shotgun and shoulder flamethrower, and he would have the best brutalities, X-rays, and fatalities. Honestly my most hoped for choice in MK11.
Spawn - This has been a request for the series for awhile now and knowing the character, it makes a lot of sense. Seeing what they've done with Injustice 2 characters (Hellboy, TMNT), I think it's more possible than ever now, especially with a Todd Mcfarlane teasing it and Spawn getting abit of a revival with an upcoming new movie. Plus who wouldn't want to see Spawn tearing people apart with his chains and supernatural cloak? Plus in MK11, with the gear system, he could be customized to look like different versions of the character as people know of how varied Spawn could be.
Ash Williams - Mortal Kombat has a history of horror icons in their games such as Freddy, Leatherface, and Jason, so why not Ash from Evil Dead? I could maybe see it not happening due to Bruce Campbell not wanting to see basically himself get brutalized horribly, but I think if they could get him to allow it and do the voice acting, this could be amazing. It could also make for amazing interactions with certain characters like Johnny Cage with their back and forth. Honestly rivals Doom Slayer for me in most desired because I just don't think there are other worthwhile horror icons that would be good and interesting, the only other one being Michael Myers who is boring as hell and wouldn't be much different from Jason. Apparently the guest characters are supposed to factor into the story, so Ash would be the best fit, especially when they can factor in the Necronomicron and Deadites into the setting so easily.
