Lol. If you were reading way back when this started, you'd know that there were Mewtwo fanboys in here. Take tocador for example. He blatantly stated that he was bias of this match up. I'm not a fanboy. Just because I main him doesn't mean I'm a fan. I'll be back later.
That was meant to be me taking a potshot at you and the Ness advocates. I don't think your fanboy because you main him, I have never thought that of anybody, ever. I think of people as fanboys when they flame other people for saying the character wins by default with a single move.
Quotingadum, if this is meant to be true to life, then the farther away Mewtwo is when Ness casts PK Flash Ω, the weaker it will be, and the less chance it has of realistically OHK'ing him. Its like a bomb, the farther away you are, the less damage it does to you physically.
If the dissipation of the energy of Light Waves were not a fact of the universe, they would go on forever and infinitely. If such were true, then a single light bulb or candle would be able to light up an entire continent at night.
Mewtwo will see the flash most definitely and it will most likely blind him, but the other stuff isn't really plausible. A flash of light making you feel strange? I don't think so. Mewtwo cry from a flash of light? Not likely in a mostly true to life battle. However, if Mewtwo can get a psionic hold on Ness, he could snap his neck if he applied enough force, but then again Ness has a chance of escaping by breakin M2's hold on him. PK Hypnosis would only really be effective if Mewtwo doesn't attempt to close his eyes, Mewtwo doesn't naturally learn Hypnosis, so he can't do the same to Ness.
Mewtwo however can use Disable, this move is a more powerful asset in a fight than you think, especially if he survives PK Flash Ω, he can then proceed to use Disable on the temporarily drained Ness and psionically lock it down. Then again, Ness has Beta at his disposal, which is a decent alternative. However, Mewtwo still isn't out of options either. He has a total of eight
offensive options aside from normal telekinesis. Ness is also armed to the teeth with many moves, but he will likely only attempt using the ones in the Ω range unless he starts becoming mentally drained, Mewtwo will also likely suffer from this problem.
Lets look at their attack options side by side.
Mewtwo Ness
-Confusion - Flash Ω
-Swift - Psi Rockin' Ω
-Future Sight - Hypnosis Ω
-Psycho Cut - Paralysis Ω
-Psychic
-Me First
-Aura Sphere
Those are the only ones Ness can use offensively in the Ω range. Those are the ones he will likely use the most; unless he is forced to use the weaker versions.. However, that doesn't rule out the use of Life Up Gamma, and Mewtwo's Recover.
Measure it up, who has more attack options? Mewtwo does, does that mean I think he would win? No, The entirety of their move sets, however, leaves them at a stalemate. Which is why I now say with confidence that they are at a complete draw.
