I think Toshiro med diff. Cyber-Sub is a different story. Canonically all Sub has on Toshiro is probably the amount of damage he can take. There’s nothing I can think of that Sub-Zero has the edge on. I believe Cyber-Sub froze the world at some point (not sure if canon) so that’s why I said it depends. Human Sub isn’t known for such feats. Hand to hand Sub takes it but overall CQC I think Toshiro dominates.
