It isn't at all. It knows only a few things, but it actually contains some wrong information.
Additionally, it contains a lot more missing information, especially in the movies department.
The part on down tilt, it says:
"Mewtwo crouches and sweeps its tail in a semi-circle. Mewtwo's fastest tilt, though severely lacking in knockback. Good as an
out of shield option."
I can't believe they didn't add the fact that it is Mewtwo's best combo starter. At all. Who cares if it's severely lacking in knockback if it combos into a lot of Mewtwo's moves?
On forward air, it says:
"Mewtwo performs a dark energy-infused swipe. One of the fastest aerials in the game, having 5 frames of start-up and high knockback, making it one of Mewtwo's viable KOing options. Although its low range makes it difficult to connect, it can be used as a follow-up from a down throw. KOs at around 143%."
It is not one of the fastest aerials in the game. And, it's not hard to connect at all. It doesn't really have low range to it. Plus it's so easy to follow up after a down tilt.
Hell no it cannot be used out of down throw. That's only if your opponent is a dork.
On down air, it says:
"Mewtwo backflips and then performs a downward arcing stomp while its foot is infused with dark energy. It has been significantly buffed from
Melee, as it now sports somewhat fast start-up (Hitting at frame 15, which is 1/4 of a second in
SSB4), very high knockback scaling and is an extremely powerful
meteor smash when sweetspotted. Grounded opponents are sent diagonally upwards with high knockback, which further makes it a viable KOing option overall and one of the best aerials in the game. KOs at around 134%."
It's not one of the more viable KO options of Mewtwo. And, how is it one of the best aerials in the game? I can understand it's a pretty good one, but one of the best in the game is way, WAY too far fetched. It is unexplored, sure, but right now it is obviously not one of the best aerial moves in the game.
On down throw, it says:
"Mewtwo telekinetically slams the opponent to the ground and spins to whip them with its tail. Lowest knockback out of Mewtwo's throws, making it used mainly to set up combos into a forward smash, forward tilt or forward aerial."
Whoever was the writer of this must be just as bad as all the other For Glory Mewtwo's just because of this. It doesn't combo into those things at all and it only barely combos into a forward air.
On up throw, it says:
"Mewtwo telekinetically swirls the opponent around its body before launching them upwards. It was the strongest up throw in the game until update 1.0.8, when
Charizard's up throw surpassed it when it was
buffed in that same update. Despite this, it is still one of Mewtwo's most viable KOing options, especially while under the effects of the
rage mechanic. KOs at around 142% against most opponents, although lighter opponents are KO'd even earlier."
Excuse me? I will say that Charizard's has more KB, but Mewtwo's is still the best because of the angle. Why didn't they put it in there?
On somewhere else on the wiki page...
"Mewtwo has received a mix of buffs and nerfs in the transition from
Melee to
SSB4. As of update
1.1.3 it is debatable whether it has been buffed or nerfed, due to it being a low-tier character in
Melee. Although Mewtwo's buffs are significant, Disable and Confusion in particular, they do not properly compensate for its nerfs to its approach, combo game, and survivability, and its major flaws from
Melee being retained, or even worsened. However, since both its buffs and nerfs are significant, it is hard to tell whether Mewtwo, as a character, is better than it was in
Melee or not."
Are you freaking kidding me, man? Do they not realize how much better Mewtwo is now? There isn't even a debate whether Melee Mewtwo or Smash 4 Mewtwo is better. It's undoubtedly Smash 4 Mewtwo. Now stop thinking like that, damn.
How do they not compensate for it's nerfs? I'd also like to talk about when it says its combo ability was toned down.
Do they not realize that Mewtwo's combo ability is actually better than many characters in this game when you put all of his combos together? I think Smash 4 Mewtwo has more combo ability than Melee Mewtwo.
It's not hard to tell at all if Smash 4 Mewtwo is better than Melee Mewtwo. Melee Mewtwo is a piece of garbage thrown in a garbage disposal. This one is no garbage.
There's more to this, but I think you get the point. SmashWiki is incredibly flawed and I highly doubt whoever wrote the wiki page for Mewtwo knows as much as any good Mewtwo around here.
Wanna correct it with me?
