Sakurai angle
The Sakurai angle is a special knockback angle programmed into certain attacks in Super Smash Bros. Brawl. While it reads in the game data as an angle of 361 degrees, the game treats it as an angle of 37 with a unique property - below a certain knockback, targets struck do not leave the ground. The Sakurai angle does not correctly tilt the impending angle indicator; it will remain at a flat angle.
As its angle is 37, the Sakurai angle is near the semi-spike threshold.
The angle's name is derived from the fact that it has a natural 11% chance of tripping, whether the move is given a trip chance or not. As Masahiro Sakurai is slightly infamous for making tripping existent in Brawl, it is hence named after him. It is unknown if the angle exists in SSB or SSBM.
