I'm also not sure why this debate is relevant to the fight at hand. Are we arguing that Vader could somehow use it as an offensive ability against Storm? To what end? He'd have to be in any kind of range of her, which is unlikely, and there's no promise that the electrical current would even bother her physically.
If we're arguing that being able to use the ability could mean he would be able to withstand Storm's lightning strikes, that's just silly.
At no point was it suggested that Vader's ability to use Force Lightning would affect his defence, or lack thereof, towards a bolt of lightning.
I only brought it up as an example of how Vader's skills and weaknesses have been put under the microscope far more than those of Storm. It has just been assumed that she wins because "she can use lightning, which Vader is susceptible to;" it was essentially being treated as
deus ex machina and I was just suggesting that if Vader was able to use Force Lightning, which would be deployed faster than an actual bolt of lightning, or Storm was fighting a Sith/Jedi that can that it would come under far more scrutiny; a point that has been aided by how you have just assumed that Storm would be able to withstand Force Lightning rather than produce any argument as to why. Physically, aside from her mutant power, is Aurora Munroe just a normal human, with no defence against such attacks?
On top of that, at no point has her actual ability to hit a moving target been established nor has the idea that Vader can pulverise her with the Force, which she has no defence against, before she could conjure up said lightning been countered.
I have no problem with admitting that I think Storm
could defeat Vader but not in the scenario that has been presented so far for her ability to use lightning is much less of a
deus ex machina than it is
mors certa. Storm needs time to manipulate the weather and even if it is just a few seconds for the clouds to form and the friction to build up enough to produce an electrostatic discharge, that is more than enough for a ruthless killer like Darth Vader, especially when he has access to a power that acts more quickly than that of Storm and incapacitating telekinetic powers that she has no defence against.
