Exactly what op says, this makes him unique in that aspect, almost like Marth's Side Special!

Pic of the day. Little Mac's side smash attack is his straight right punch...but it can transform into an uppercut if you tilt diagonally upward, or a body hook if you tilt diagonally downward. The body hook is the most devastating of these moves and it doesn't blast the opponents away.

Bonus:The trick in activating these punches is to avoid tilting the controls diagonally from the get go--instead, tilt up or down right after the smash attack starts kicking in. You can also tilt up or down while you're powering up.

It would be good if every character has that ability (I guess that will be the case anyway).

I was suspecting that the big leap this gen in Smash Bros would be more complex movesets, This reinforces my little theory.

so far its little mac exclusive. Just think of Marth's Side Special. Its the only side special with different ways to execute the attack!

It makes sense for Little Mac to have these extra close-combat moves, so I don't see this happening for all characters (if any more at all)

NOOOOOOOOOOOOOOOOOOOOOOO. While these changes sound interesting to me I can't help but think it will be the undoing of smash. I have always been afraid that having a traditional fighting game developers make this game was  bad idea.

Oh is it just Little Mac?  I'm okay with that.    

Mac is sounding op

Most characters have been able to do this since 64.  You can tilt a smash up or down.  With Mac, it's a just a bigger change.

Have you seen his air time? Its utterly useless. Terrible recover, no hopz, and aerial attacks arent good.

I know what you mean, but clearly this is not the same.
