In this current demo for sure. His kill moves are great. Last demo it was hard. I did testing against another Mario in both demo's in the middle of FD with bad no DI.
My results
9a down smash: 125%
9b down smash: 95% (Holy crap)
9a up smash: 105%
9b up smash: 92% (Nice)
9a f smash: 120%
9b f smash: 98%
9a fair after down throw: 92%
9b fair after down throw: 130%
You trade a weaker fair for all your smash killing 20-30% earlier. I'll take it.

Why is downsmash so freakin scary

It actually isn't that bad. I realize this more as I use him. Proper DI could can survive to 110%. Even higher with better DI. That's reasonable for the range it has. Its knockback also mirrors Dr. Mario's Dsmash in Melee. It's very similar.

But it's hard as hell to even land the move in this game on good players. The move is so short ranged and predictable when it will be used. Honestly, if you get hit by it, you did something wrong in your spacing.

Dsmash is ridiculously strong, too bad it's range is so small.
Usmash has so much priority too, it's like one of the best anti-airs in the game.
I wouldn't fsmash is like PM or Sm4sh good, but it's still pretty strong for something so short in range.

He reminds me a lot of doc in this game. Minus the strong fair of course. Still Mario has a much easier time killing in this compared to Melee, Brawl, and 4. I think he's high or mid high in this game. Obviously range and recovery are issues but when he gets in :O.

His fair is actually strong as well and stronger than it was last demo.

I prefer Mario this way because from what I read up about him and used in the main games, Mario has strong comboing ability, but lacks strong finishers. His combos are not as good as last demo due to the nerf in hitstun, but he is still awesome and great at edge guarding as well. I'm trying to get better with Mario by practicing with him as much as I can.

@Zalo
Or they confirmed it with a fireball or read a roll.

Last demo fair kill from 90-110% off down throw. This demo it kill at 130-150 off of down throw. Look at the results I did above.

double post oops

I missed that, but it doesn't really work like it does in PM?

What did you perform this on human or CPU?

Both were tested in the middle of FD against another Mario with no DI.

Player or CPU?

CPU is gonna DI into the stage. While the AI isnt good for testing strategies and such, you can test how soon something kills perfectly fine.

One day, I hope mcleodgaming makes Mario taller... He's too short.

Ummm that's how Mario is in the main smash games and even in his own series.

His smaller size also means a smaller hurtbox.

He's definitely a little too short. You can definitely feel his range suffer a bit from it too. He's shorter than Sonic, Wario, Mega Man here; when he's at a more similar idling height as them in the official smash games.
