As for his throws, his down one can lead to jabs, dtilt, dsmash, or if you tech chase, another throw even. As for his three up throws.... They chain with the chute at early percents.... And you can use Uair to keep them airborne or smack them with upb. I don't like the throws either.
You know that his sideb has long endlag and cancels with A moves or a double jump. Also, if you time it right and use sideb as he lands, the move will have normal endlag, allowing it to chain it with itself, though that is tricky to do, for me at least.
Other things notable are his amazing dtilt that needs no explanation, as well as his super fast utilt. His ftilt is also decent since it's now fast and has small endlag, so it chains with itself a bit. His chute has great range above him, and it beats most dairs of the entire cast. His regular Nair retains it's vbrawl use, and it's still good for that, as is his fair and bair.
His fair might actually be worse than his vbrawl version. Normaly, the hitbox stayed out for a long time, but that benefitted him a lot in minus since he his really fast. Now, it requires that you time it more carefully since it's hitbox doesn't stay out as long. I personaly feel that this nerfed him a lot, which is really lame since he is a c tier character at best anyway. There is also the fact, that the animation doesn't end when the hitbox is gone, so you can't visually see when the hitbox is gone.
His dash attack is only good for hitting people that spot dodge. It's really weird having a fast character with such a slow dash attack. That's why you will be throwing out sliding smashes and grabbing from his dash half the time. This is okay for him since his attacks are really fast, so you can smack people that try to dodge you. Thing is, he gets walled by shields easily. Outside of his Usmash, dsmash, and certain judge hammers, he can't inflict shield pressure at all with his attacks, so learn how to dash and grab people, even though his throws aren't that great.
Also, his final smash is a freaking octopus, and he dies in a few hits and gets juggled easily. Did I miss anything?
Oh yeah, his dair is a great spike and cancels early with a double jump or into upb easier. It also combos with the cute super easy when it hits grounded foes.
His upb doesn't give him as much invincibility on startup as it does in vbrawl. I'm also not sure it goes higher than in vbrawl, so this move may be worse than vbrawl a upb.
Back to his dash attack, it has a weird cancel where if you do certain A attacks, like his smashes, near the end of the move, he will do the attack and slide super far. I can't get the timing down for this.
Also, his rolls and dodges are bad. Be careful.
That pretty much covers him.
