So who's excited about possible guest characters? I know some people hate them but guests are essentially a part of the series' brand now so they're to be expected. It will be interesting to see who makes it into SC6...
I'm against more Star Wars nonsense nowadays, but Kylo Ren being in just to recycle+merge Vader & Apprentice move sets would be good.
Kratos would be good bring back as a guest simply to bring Aeon's moveset back to the original owner, give Aeon his "Lizardman" style back. Also not many people got to experience Kratos on PSP, and they can update + improve him from his PSP/Aeon moveset to reflect his more recent games.
Dante from Devil May Cry was originally considered as a guest for SC3 as he was one of the most requested guests back in the day after SC2 came out with guest characters. Would be interesting if he were realized considering rumors of a new DMC game, though I don't think he would fit too well with SC's medieval theme.
On the Nintendo side if a switch version releases, there's the obvious re-inclusion of Link, or a Fire Emblem character would fit well I suppose, but let's not forget that Bayonetta was considered as a guest character for SCV, but due to over-complexity of her style and design, they scrapped the idea and simply had the Bayonetta artist create some costumes to be included in the game (such as Ivy 2P). She's in Smash bros so maybe it will be feasible to put her in SC6 after all, but she has the same issue as Dante of being too "modern".
If they go the route of doing an exclusive for each console like SC2 and there is an Xbox One version, I can see them putting a Killer Instinct character in, Spinal being the most fitting. What do you guys think?
