Really feeling what they did with Noob Saibot on the update. His new mask and outro are sick. Really upgraded the character IMO. Only thing he's really lacking now is story. They haven't did anything to expand on him story wise since they revealed him to be Bi Han. Transitioning from UMK3 to MK4, they had him like he was going to be a major player in the story line. He wasn't. He ended up being a secret fighter. Then he resurfaced in MKD and not only was he the sub boss, but the Bi Han reveal was big as mentioned.
Noob has potential and being he is the original Sub Zero, but has been years since he's been significant. He's just been a henchman. We haven't seen him lead. For example, Cetrion says her alliance with Noob was only temporary. What alliance? Why was there an alliance?
He interacts with Scorpion and Sub Zero in story mode, but nothing significant happens. If they were going to kill Hanzo why not have it done at the hands of Noob Saibot instead of D'vorrah? Then he could've faced off against Scorpion. We don't even see Noob in the Nether Realm. Then he gets mopped up by Jax/Jacqui. Would've been much more crazy to see him protecting the hourglass instead of revenants. Dude is composed of an army of shadows and has had his powers enhanced by the soulnado, but the only time he does anything remotely interesting is his fight with Fujin.
