A tether recovery (ワイヤー復帰, Wire Comeback) is a type of recovery move in Super Smash Bros. Brawl, Super Smash Bros. 4 and Super Smash Bros. Ultimate that lets the player latch onto the edge of a platform with an extendable item or hook. If there is an open edge when it is used, the tether will automatically connect to it. Pressing the standard attack button after grappling an edge will pull the player towards it. Tether recoveries are effectively the successor to the wall-grapples in Super Smash Bros. Melee, though tethers can only grab onto unoccupied edges as opposed to any wall. Most tether recoveries are grab aerials, though some special moves and aerial attacks also act as tethers.
Contrary to what they may appear as, most non-grab aerial tethers are not a command grab; rather, they utilize a standard hitbox with a property of sweetspot edges, as with most non-tether up specials as well as other recovering moves; in fact, Fishing Rod, Grappling Hook and Sword of the Creator are the only non-grab aerial tethers that function as a command grab (although they have slightly different properties from standard command grabs).
Many tether recoveries have a larger range than regular recoveries and also home in on the edge, allowing for better control. However, in Brawl, if the edge is currently occupied when a tether recovery is used, it will fail to grab onto the edge (the player can, however, knock other players off the edge should the tether hit the opponent). None of the other players can grab the edge while a player is attached to it with a tether (prior to SSB4), making it a method of edge-hogging other players. A tether recovery can only be used three times without touching the ground; if it is used a fourth time, the tether will simply hover near the edge, and the player will have to make use of their remaining jumps. After grabbing an edge with a tether, there is a short cooldown before the player can tether onto an edge again. In Ultimate, tether recoveries also count towards the newly introduced ledge grab limit. Attempting to tether after the limit is reached will have the tether bounce off the ledge. Simply tethering the ledge will add to the limit, even if the user does not retract the tether to grab the ledge themselves. Doing so however will not add an additional grab to the limit.
As of Super Smash Bros. 4, multiple characters can latch onto a ledge at once if using their tether, but once players pull up to the ledge, normal ledge grabbing rules apply.
In Super Smash Bros. Ultimate, regrabbing a ledge with a tether recovery gradually decreases the intangibility on getup, as a part of the new universal ledge mechanic. However, unlike normal ledge grabs, tether recoveries do not remove the intangibility when hanging on a ledge for unknown reasons.

Note that characters that have tether recoveries as a special move cannot use their extended grab as one.
Several characters with tether recoveries had their movesets changed while Ivysaur was cut.

Link no longer possesses a tether recovery due to Breath of the Wild (which is the basis for his current design) lacking both the Hookshot and the Clawshot, although his counterparts Toon Link and Young Link retain the Hookshot as their grab. Brawl veteran Ivysaur retains its tether recovery up special, and newcomers Joker, Byleth, and Min Min use a tether recovery for their up specials.
