Chain grab

A chain grab (also chain throw) refers to a series of grabs and throws that the victim cannot escape. Generally, a player throws the opponent a specific direction (most commonly down or up), chases the enemy's directional influence, and grabs the opponent while he is still in mid-air and before he can tech. Sheik and the Ice Climbers are examples of characters who rely heavily on chain grabs. The usefulness of chain grabbing in Brawl has been reduced with the addition of Prat Falling. Generally, Fast-fallers, heavyweights, and large characters tend to be more vulnerable to chain grabs than floaty characters, lightweights, and smaller characters.

Controversy
Chain grabbing is a controversial technique within the community. Many players consider it an unsportsmanlike move because it can be inescapable when perfected by the grabber. However, tournament players generally see it as a valid technique which characters like Sheik, Marth, and the Ice Climbers need to overcome other deficiencies in high-level matches.

Examples
Characters with well-known chain grabs include the following.

Super Smash Bros. Melee

 * Sheik: can chain most characters to medium percents with her down throw
 * Marth: his up throw can be used against Fox and Falco, while his forward throw can be used against lighter characters like Peach and other Marths.
 * Ice Climbers: through desynching, an Ice Climber player can achieve devastating chain grabs against a large portion of the SSBM cast. The player controlled Ice Climber alone can chain grab people at lower percentages with their down throw.
 * Captain Falcon: can chain throw characters of medium to low falling speed with his down throw and can tech-chase fastfallers into another grab after an up throw, creating a de facto chain throw. Captain Falcon can also use his up throw to chain grab medium to fast falling characters at low percentages.
 * Mr. Game & Watch: Can chain grab with all four of his grabs to medium high percentages. Very versatile since all of his directions for grabs can be used for chain grabbing.
 * Peach, Pikachu, Pichu, Fox and others: many characters can use chain grabs against the fast fallers.
 * Mario and Dr. Mario can also chainthrow most characters in the game, depending on weight class, with either up throw or down throw.
 * Peach can chainthrow another Peach using her down throw.
 * Fox can chainthrow another Fox or Falco using an up throw usually from over 10% to death if the Fox player is good enough.
 * Mewtwo can chainthrow with its down throw, though it has very tough timing.
 * Link can limitedly chainthrow opponents at very low percentages with his forward throw, however it is easy to DI out of.

Super Smash Bros. Brawl
The following characters can be chain grabbed by both of Yoshi's methods. Ganondorf, Meta Knight, Falco, Squirtle, Lucas, and Sonic (Sonic is much harder to do, you need to react quickly when he releases or else he will escape.)
 * Bowser can chain grab by air-releasing the opponent.
 * Falco can chaingrab with down throw at lower percentages, usually giving around 42% to most characters, more to the heavyweights.
 * Ice Climbers can chaingrab grab by backward, forward, and down throws. There are many chain grabs that the Ice Climbers do such as grab spikes, footstool grabs, release grabs, and more; an Ice Climber player can make the chain grab infinite. A lone Ice Climber can only chaingrab by down throws at lower percentages.
 * King Dedede Chaingrabs with down throw, he can also chain grab by the wall infinitely. He does not need a wall to infinite some characters, such as Mario, Bowser, Samus, and Donkey Kong.
 * Kirby Chaingrabs with his down throw on fast fallers for the early percentages.
 * Marth can chaingrab with his forward throw on certain characters like Captain Falcon at low percents. His up-B can escape from most, if not all chaingrabs.
 * Lucario can chaingrab with his Force Palm for some characters like Captain Falcon. He can also chaingrab fast-fallers with his up throw at lower to medium percentages. He also do an AAA combo to a Force Palm, it works for heavy characters and some certain characters like Sheik and Wolf, etc. and stops around 37% and sometimes 50% on heavy characters. It only works if Lucario is at lower percentages.
 * Meta Knight Chaingrabs with down throw on fast falling characters like Wolf at low percents. He can do it to everyone, but requires good timing and humans will be able to escape it. Also, his back throw can be done in succession a low percents for nearly every character. His up throw can also be used against some characters.
 * Mr. Game and Watch Can chain-grab with his down-throw to medium percentages by hitting the enemy once with his standard A move, then re-grabbing.
 * Olimar can chaingrab with his down throw. However, this chain grab is very situational. It only works at low percentages, but if it can be pulled off, it is a guaranteed 30% on the opponent.
 * Peach can chaingrab by down throws, turning to the other direction and grabbing him/her, works at lower percentages and only fast-fallers.
 * Pikachu Chaingrabs by down throws on C.Falcon, Wolf, Fox, and King Dedede and forward throws on most heavyweight characters. Pikachu can also chain throw with his down aerial against some characters.
 * Pit can chaingrab with forward throws on certain characters like Fox and Bowser, it only works at lower percentages.
 * Yoshi: 1. Chaingrabs by using the A attack while grabbing. You chew (the attack) them until they escape. Then do a pivot grab and grab them again when they come back down from the air. Called Infinite Pivot Grabbing, although the name could change or have multiple names. 2. Chaingrabs by using a Forward Throw.
 * Zero Suit Samus can chaingrab most characters with her forward and back throws.
 * Wario can infinite chain grab with his down throw on characters like Bowser.
 * Note: In order to chaingrab well/correctly, you must perform a Dashing Shield Cancel Grab, not just a Dashing Grab.

Practicing
An easy way to master the chaingrab is to practice with Dedede's down throw on heavy characters such as Ganondorf against a wall, such as the ones in Shadow Moses Island. Simply grab the opponent, perform the down throw, and grab him again once he or she is on his feet. This is easier to do with a human player controlling the target you're trying to chaingrab for the sake of better cooperation. The idea behind doing it against a wall is so that rather than Ganondorf moving towards the edge (and eventually off of it) with each consecutive throw, you can do it indefinitely because the wall will keep him within Dedede's reach. Once you've mastered it with heavyweights, it's recommended you try it on lighter characters since it's harder to do against them.
