T-pose
A T-pose, sometimes known as a bind pose or reference pose, is the default unanimated state of a model in 3D graphics. This pose is often with all of a model's various parts straightened out or flattened for ease of animation. For most characters, this results in a pose where the legs are straight and the arms are pointing sideways in a T-shape.
Description
In works that use three-dimensional computer-generated graphics, such as animated films and video games, character models are created, textured, and rigged before any animation work is done. The "bind pose" is the model's default pose used during development, which is then deformed to create animations. As expected, the Super Smash Bros. series uses bind poses to animate its characters, and players can potentially view the original bind poses using external programs, such as BRRES Viewer.
In most cases, bind poses take the form of a "T-pose"; the character's arms are stretched out horizontally on either side, resembling the letter "T". The vast majority of characters in Smash use standard T-poses, but certain characters have variants due to their body characteristics. Yoshi and R.O.B., for instance, have their arms extended in front of their bodies, while Ganondorf's armour in Melee forces him to take on an "A-pose" instead of a T-pose. Although Link's model uses the standard T-pose within the files ofSmash 4, if his bind pose is forced to display through glitches, it will instead appear as a more dynamic battle pose.
Characters that use model effects for facial expressions (such as Sonic or Kirby) may appear with unusual facial expressions when viewed in their bind pose. Sonic's eyes, for instance, will always appear closed, while Kirby's mouth will be forced into the "O" shape used for his Inhale.
In gameplay
Bind poses are generally only intended for game development and, in theory, they should never be seen in the actual gameplay of a final product. In Super Smash Bros. Brawl, however, some attacks will cause bind poses to appear for a single frame, such as Olimar's Pikmin Chain and Ganondorf's Beast Ganon; seeing these bind poses, however, requires almost perfect timing with the pause button, as well as external help by slowing the game's pace down considerably.
Hacks and glitches are the most common method to seeing bind poses appear in gameplay, as they act as a failsafes for animations that do not exist, thus helping to prevent game crashes. Moveset swap hacks, for instance, are particularly notorious for featuring numerous bind poses, as bind poses are used when the two involved characters' special moves have an unequal number of frames or if the two animations have different names. Furthermore, hacking ordinarily non-playable characters into brawls, such as Giga Bowser, will cause their losing poses to be the bind pose on the results screen, due to a lack of "applause" animations. In Smash 4, a glitch could also force bind poses to appear on the results screen if the Home button was pressed 1 frame before the beginning of the victory pose, as it could prevent the game from properly loading such poses; this glitch was later patched out in version 1.1.0. Versions 3.0.0 and 3.0.1 of Ultimate have a glitch that can be done in Stage Builder that allows the player to put any character in a bind pose; it's done by inhaling or swallowing an opponent with Kirby or King Dedede while testing a stage, and then resetting by pressing, L, R, and A, along with Start to pause the game, as the pose is only visible for a single frame.[1]
