u kno canonically inferno and nightmare are the same person right?
I won't speak for the others, but in my case yes, I know. What about it though? It's as if I were to argue and say "Abyss and Zasalamel is supposedly the same being" when someone wants the former to return, but even though it's true, they were both present in SC3 and played quite differently.
People are talking about the "character" Inferno as the fire creature with random weapons and its unique helicopter moves. It doesn't really matter if he and Nightmare are the same being as both can still be canonically present again (like in SC1), especially since now it has a new host and isn't a "phantom" like in SC3.
I think the return of "Inferno" might be a bit unoriginal though and quite unlikely somehow. It's no big deal with me since I'd think of it as an extra.
To return on topic, I can't help but see that "mouth" on Nightmare's helmet. I personally don't really like that aspect of it, but on a more humor point of view he looks like an evil Optimus Prime.
As for the story, yeah I'm also interested in how the two will interact with each other after 17 years. I also hope that this story mode (developed alongside Cyberconnect2) will have a straightforward "canon" story similar to how it was in MK9, while keeping the arcade mode with the multiple "single character endings". Seriously, seeing Nightmare, for example, in action during story mode cutscenes other than the endings would be a treat.
