ZELDA
<Standard Special Move: Nayru’s Love>
Some sort of crystal forms on Zelda’s sides and revolves around her, shielding her body. It won’t last as long in the air as it does on the ground, so be careful.
The crystal is like a deflector shield. Projectile weapons will bounce off it.

Use it quick and watch it work!<Side Special Move: Din’s Fire>
A short burst of flame... Uh, but it’s not too powerful...

Pop!See, you can’t just use Din’s Fire like that.
First, you have to hold the special-move button and store up flame energy. Next, you have to remember to aim the flame by tilting up and down. Once you’ve stored up enough energy, Din’s Fire is unrivaled!

If you use it right, you can hit opponents even at this range!If you’re the target of this special move, you can learn the timing of the explosion pretty easily. Get in the air and perform a midair dodge (use the shield button while in the air) to try to dodge the attack.
Sakurai's words clarified: Din's Fire works much more powerful in a further distance. The hitbox becomes bigger and the knockback is stronger. This move can now kill at high percentages. This is a great improvement to Zelda contrary to previous reports that his move has been nerfed. And by the way, when you charge the move, it's the same as Melee. It isn't a stationary charge.<Up Special Move: Farore’s Wind>
This special move can be used for evasion and to get back to solid ground. You’ll fly in the direction you tilt the Control Stick at the moment Zelda disappears.

Now tilt the Control Stick in the direction you want to go.You can go to the side, up or down. It moves you quite a long way, and may be quicker than running. I think you’ll be using this move a lot in The Subspace Emissary.

Whoa! You might not always make it to a safe landing, so be careful!
ICE CLIMBERS
Play a little and you’ll soon find this out for yourself, but here’s some advice—when fighting as the Ice Climbers, making sure your partner, Nana, stays alive is key.

Your attacks suffer when you’re alone...

But together you’ll hit harder and score multiple hits!
The difference is even more dramatic when performing special moves.
<Standard Special Move: Ice Shot>

Popo fires off a lone chunk of ice that sliiides away.

With Nana by your side, your attack is doubled!
With two shots you can relax, safe in the knowledge that you don’t need to worry about your attack being reflected, since one projectile will cancel out the other upon being repelled.
This will be a constant source of headaches to your opponent.
<Side Special Move: Squall Hammer>

Popo spins around and around. It’s not useless or anything...

But this is much better! You can also rapidly press the special-move button to rise higher into the air while doing this move, a secondary function whose rate of ascent is also improved when you perform this move with both climbers.
<Up Special Move: Belay>

Popo’s just going through the motions here. He probably had to work out a kink in his shoulder.

When you use Belay with two climbers, they perform a feat that leaves you dazzled at the depths of their friendship! Belay has virtually no effect when performed alone. This is a real example of how you’ll need both climbers for success.
<Down Special Move: Blizzard>

This short-range projectile move freezes the enemy.

But with the two climbers together, you’re guarded from both sides!

Use it in the air and both climbers will face the same direction for double the power! Following up a small jump with a midair blizzard can come in pretty handy.
So playing Ice Climbers boils down to Nana. It’s all about Nana.
Like a team of skilled mountain climbers striving to reach the peak, you must honor and cherish the bond that binds you with your teammate as you fight together.

Ahem... And let’s overlook our friend’s occasional impulse to wander off, shall we?
