A recovery is the attempt to return on-stage after being knocked off. Some tools to achieve this end are the second jump and the third jump (usually an up B attack).
It should be noted that some characters do not have an up B attack as their recovery, for example, one of Zero Suit Samus's recovery is her down B attack, the Flip Jump. Also, some characters have a Tether Recovery.
