Like the title says, this will sound really dumb, but I'll just explain to you what I think the deal is with this Noob Smoke "Fusion"

Alright here's the deal:

The Tekunin have already seized complete control over Japan, and now they're looking for more areas to conquer. They arrive in Antarctica, (Being retarted robots, they don't realize there is no where to conquer there) but they run into the newly reformed Lin Kuei. "The Cold War" breaks out(...being retarted robots, the Tekunin don't realize this name has been taken)

The Lin Kuei eventually run them out, but not before Sektor can capture Smoke. The Tekunin regroup in Japan and hire Noob Saibot to help them destroy the Lin Kuei, but Noob is tricked and is eternally bound to aid Smoke(Due to a new technonolgy they recently discovered), unless Noob and Smoke take out the Lin Kuei. Smoke unwillingly accepts, and they set off on their erotic journey...

Yes, I know I'm stupid...but it's as good of a guess as any.
