Let me tell the people that think that Toon Link is vastly different from Link. He's not. Infact, the only thing that separates them from being identical is thay Toon Link has multiple hit boxes on his moves.
Every clone is separated by this mechanic. Ganandorf, Falco, Roy, Luigi, and even Young Link (which Toon Link filled that spot.) So saying that they're different is like saying you changed your mentality on what's ok to be a clone, and what you see when someone sells out and just puts them in because of the money.
I didn't read a single word here thats correct at all.
let's start with Link and Toon Link.
Their specials are the same moves. However they all act differently.
Link't arrows are much faster but don't travel as far, His boomerang travels back with that wind gimmich while TL's one gives damage. Links upB hits 1 time grounded and does much more knockback. While TL's does multiple hits.
The only move that you could say is the same is really the down B because the only thing that they do not share is how the explosion looks.
Their Arials are not the same either. UAir is kind of the same. Dair makes TL go straight down while link keeps his momentum the way it is for most part. They are both going to spike but Link's didn't spike in brawl and TL's did. Nair, Bair and Fair are all completely different. So I am not even going to talk about this.
Smash attacks do look alike however they are not the same. Links Usmash does 3 hits and TL's only 1. TL's Dmash does not give Vertical knockback on the first hit but instead gives pure horizontal Knockback. Link's does give vertical knockback on both hits making it nearly impossible to hit both hits. The forward smash is is kind of the same as Dsmash. Links Fsmash deals pretty high knockback on both hits, However TL will never kill with his first hit and instead sets up the 2nd hit which is actually easy to DI to.
Tilts, Utilt I'll give you that move, they are very much alike. Dtilt can spike if using Link, However not when using TL. Ftilt could also be kind of alike, nobody uses that anyway. Dash attack was alike in brawl however Link has another one now, another move that is not the same any longer.
Now on to alllllllllllllllllllllllll the other stuff, Link falls faster, is heavier, has less airspeed, lower jumps, lower upB, Link does more knockback, link has better range overall, Does more damage overall. And TL is much much smaller. and that range comes back in most of the moves.
They are not the same, they won't be the same in the next game and they will never be the same in the future either.
If there ever has been 1 "Clone" that was made very well considering not playing like it's counterpart at all it would be TL.
now about the part that I made bigger. This is nonsense
Roy and Ganon have the same moves Marth and Falcon have. The only moves Ganon and Falcon do not share is Fair. How does one have more multihit moves then the other? Fair have 1 hit in both cases to.
Roy and Marth share every single move, so again which one do you think has more multihit moves? I would like to know.
Luigi especially in brawl does not work close to how mario works and the same would go for Falco.
Now Young Link. TL did not fill that spot at all, Young Link is not relevant in any way and was the exact same as Link. I allready made clear that Link and Toon Link however do not even come close.
You are like all people free to have your own oppinion but posting stuff thats far from true is not going to help anyone. I didn't even have to defend Lucina here because the others will do that but Clones are going to be in smash and in many cases do not come that close to their counterparts viability, whatever they are better or worse.
with that, have a nice day sir!
I've explained several times why Lucina represents an exception to the typical reasons to dislike clones, rather than being another Melee Falco/Ganondorf/Young Link, but I guess most people are only interested with basing their opinions off of the final moveset.
