I already made my estimation of what I wanted his weight to be, and indeed it came close to 104 as well.
In PAL Melee, Mewtwo's weight was 89, that's 17 points higher than he has now. 17 points is a whole lot, as it's the difference between NTSC Melee Mario and NTSC Melee Bowser, one being a so called "middle ground" of weight and atritbutes, the other being the "extreme heavy weight".
I just find it weird that Sakurai acknowlegdes in PAL Melee that Mewtwo was too light in NTSC and Japanese Melee by buffing his weight, to give Mewtwo the biggest weight drop in Smash history for this game... 17 points of weight is something you'd take from characters as
if he where to get back... Not a character who's most major complaint since day 1 was his weight being too low...
If they'd add 17 points to his PAL Melee weight however, that'd be 89 + 17 = 106, which is just slightly above average, and just above the "regular but trained human scale" which is
and
at 104. And just below
with his armor, muscles and 107 weight ranking. He'd get the exact weight of
, who also relies mostly on punishes, trading, spacing, reflecting projectiles and knowing when to shoot his projectiles...
It's indeed extremely humiliating how Mewtwo is portraited again in Smash 4...
