Kuno's not that smart. one line would be going to his head. kill ranma. and even with kryptonian powes he couldn't do it.

No offense, you know.
But...
This is one of the 10th most screw up concept ever concieved! right up there with Kuno as a Wu & Akane as a Sanjiyan!
If you want to infuse a guy with superpowers, pick a saner ppl. Like... Hiroshi or Daisuke!
Heck even Gosunkugi is a better choice! (Though not by much)
Next you'll be telling me that Ryouga's got a hold of the Green lantern's ring And that Akane is actually holding Thor's hammer all the time.
Not that you grammar is bad, just that the concept is screaming OOC all over.
Kuno as an overall justice figure is as believable as Happi the Priest concept. That's my final word on this.
My vote is to scrap this and start over with a more saner character. Take your time, there are pleny of Nuts out there that's suitable for the fusion. >_^

Are you making Kuno into Superman? I can't say that's a good choice. Personally, I have a hard time seeing anything but bad news happening from that. Kuno is majorly messed up in the head as far as I'm concerned.
But you are the author. The grammer and spelling appear to be good. Have a great day.

Honestly, although I don't like the idea of having or getting power one didn't work for, this story does have a good feel to it.
Continue it, and show us why you started it. (O.o Whatever that's supposed to mean...)
Alex: Hehe, I KNOW he wouldn't stand a chance against me!! HAHA!!
Alex Ultra: Alex, no one stands a chance against you... so just shut up.
Alex: But I wanna gloat!
Alex Ultra: Not now, I have a headache...
Alex: [Sulks]
