First, why do the nanofibre's have to be stronger than Kevlar? Kevlar is already pretty darn strong, and thats not a special type of fibre. Its a layering of different materials together. Even if it's weaker than kevlar, it'd still be pretty darn strong for _any_ material.
Second, for the electricity to be generated in the muscles.. thats a little bit silly. For it to come from the main power source on the other hand, thats a bit better and makes more sense. Even for a magical entity.
Thirdly, for the net, lets say that it stops signals at their source. For a human, that would be around the spine and lower brain. For Vordak's character, that would be around it's power source. However, Vordak's power source doesn't send out little signals like a human would: it would send out fairly large amounts of electricity to make the fibred muscles move with any degree of force, much like a robot. I would say that the net may restrict the amount of force that it's muscles would be able to output, but not restrict it entirely as it isn't used to dampening signals of that strength.
So, what we have is a weakened Rauchnaut, but not a paralysed Rauchnaut.
Can everyone agree on that, if that is the only point in my list that you do agree on?
