Snacks has a pretty good one. I just haven't fought a Greninja in so long I'd forgotten how bad he was. Just because Amsa is a good player in multiple games doesn't say much for Greninja the character. He is completely non-threatening. While I disagree with Zero's bottom of top tier/top of mid tier (every character is high tier to Zero), I agree when he said Greninja just isn't all that well designed, there's just not enough unique to his moveset. His pummel does 1%, I mean c'mon. Can he even duck under Wii Fit Trainer's sun salutation?Replace him with a turquoise Jigglypuff recolor, I say.
Edit: looked it up cause I was curious, turned out Amsa placed 33rd at EVO 2015 in Smash 4, so he didn't make it into top 32. Amsa hasn't had any great international performances since Apex 2015 (where he only got 9th, let's remember), I think he's more focused on Melee anyway.
People always mention aMSa, but he doesn't really perform that consistently. I guess because he's already known from Melee and is one of the few known international Japanese players. The next Umebura is going to have more international players, so we'll see if the Greninja players who haven't been able to leave Japan can perform.
It's supposed to be 2%, but still pretty crummy considering you're lucky to get 2 of them even at 140%+. In addition to grab having a slow startup while standing, but a normal startup while dashing. I don't know of anybody who wouldn't trade the extra range for a normal standing grab.
Greninja was a pretty poorly-designed character after the 3DS nerfs. His projectile frame data was as slow as Mewtwo and Samus's despite not being able to hold the charge, Substitute is still lame, he didn't have enough KO power. Then they improved his side tilt to not be useless and have massive endlag, but the biggest buff was to shuriken. The frame data could still be better, but the startup is 5 frames faster so now Greninja can actually camp and harass again, rather than every shuriken needing to be meticulously timed and spaced. As for the "Sheik-lite," that's a pretty common claim and doesn't really hold up when you've played enough Greninja. They aren't any more similar to each other than Sheik is to Fox or Zero Suit, they're just both ninjas. Greninja is much more evasive than Sheik, has longer range (other than Sheik's absurd forward air and needles but we don't talk about that), a better punish game, and KO setups. He's more like Fox or Zero Suit in that he needs to look for or create openings with tricky movement, spaced aerials, and a projectile, rather than Sheik who doesn't have to give a shit about any of that because she has needles.
But you and ZeRo both know the main problem with Greninja, he's just not uniquely threatening. He has good spacing and harassment and disjoined smash attacks and ridiculous movement but none of that is scary because his moves don't set up into each other. His up throw up air doesn't combo as often as most throw combos and doesn't work against some characters, nor does he have any way to decently punish airdodges when it won't combo because his forward air is so slow, his up air has no horizontal range, and his back air is so weak. His neutral air needs to hit with a sourspot to combo (why does it even have a sweetspot anyway?), and both his down tilt and neutral air have significant percent ranges where they don't combo (it combos into up smash on a decent number of characters at 80-90%, then no combo until 140%). Why does his forward air have a 16 frame startup if it doesn't even KO until 140%? Why is his up tilt so slow?
If they made Greninja's combo game actually work rather than being heavily percent, spacing, and character-specific, he would be a serious threat. As it is now, he's a really agile character with some good attributes who can finally compete again, but isn't as scary as he deserves to be.
Also his Up B shouldn't bounce off the stage, that's absurd.
