Bomb recovery

Bomb Recoveries are used to extend the horizontal recoveries of Link, Snake, and Samus.

Samus

Samus' bomb recovery is performed by simply using her Down-B bomb lay in the air, and then laying a second bomb to hit the first and bounce herself upwards. Repeat as desired. This gives Samus the ability to recover easily from any attack, and when combined with techniques such as Samus' Grapple Beam and Rising Grapple, make edgeguarding her a serious chore.

Link

Link's Bomb recovery is reasonably difficult, but it is the best way to get the most out of your recovery with Link. Lord HDL defines it as follows:
"Bomb Recovery - Third form of recovery that involves tossing a bomb up while falling and immediately using spin attack to hit it in order to perform another spin attack or change direction for hookshot use. Cannot be done by Young Link."
There are three ways to perform the Bomb Recovery:

• While returning to the stage and falling, throw a bomb upwards, and immediately Spin Attack into it. The bomb should explode allowing Link a second Up-Special, or a Hookshot Recovery (if you are not facing away).
• Use his midair jump, and immediately throw the bomb up and Spin Attack.
• Simply drop the bomb while falling, wait a moment, and spin attack into it.

If you can predict it, you could also pull out the Bomb ahead of time and have it explode in his hand after you Spin Attack. Then he can Spin again. This is usually done accidentally, and is the only way for the Links to use Bomb Recovery in Brawl, since they can no longer slash their own bombs.

Snake

Snake's bomb recovery is very much like Link's. You use C4 on yourself, and you can use your Up-B again.
