But I think that Cyber Subby won't be canon. It will be something like a secret joke character. Maybe in the challange tower.
I can't imagine how it would be canon. The original Subby becomes Noob so it's only the younger Subby who can become cyborg. I don't think they will destroy MK's one of the most iconic characters!
I feel like it will be an alternate story line within the story. We have the ability to alter lots of story elements, and I'm pretty sure Cyber-Subby and Human Smoke will have some sort of story.
