4D Bottom - X:D

X:D (X Drive) features three Performance Tips, much like D:D, which are XF (Extreme Flat), a new Tip by the name of S²D (Stern Semi Defense) and S (Sharp), the Tips are quite small however.

X:D appears to be a hybrid of D:D and F:D/ F:S. As the Tips follow patterns but do not always use the same; it can occur from XF, S²D, to S or S to S²D to XF[1], but this automatic change only takes place when Diablo is in Ultimate Balance Mode, since Attack Mode only allows for manual changes, similar to D:D. S²D only appears in Ultimate Balance Mode however. The XF on X:D is more like a HXF (Hole Extreme Flat).

X:D's purpose in Ultimate Balance Mode is that as soon as Diablo gets hit, it switches to the next Tip in X:D, but it is unsuccessful most of the time. For S, the bottom of X:D creates a small protrusion shaped like Sharp's Tip, but not of the same height and more of a ball shape instead of a fine point, giving it better defence and balance. For S²D, the protrusion becomes smaller and appears circular, much like B or WB; even though S²D is meant to be SD's upgrade. Finally, for XF, the protrusion retracts inside X:D's bottom and now appears flat, used for XF's fast and aggressive movement. Also having the height of a 145, X:D regains balance fast, after each attack in sharp mode. The "stern" in it's name seems to mean that it is a rounded off variant of SD.

For Attack Mode, whose tip changes manually, people usually use the Sharp tip. The reason is because it can provide more stamina than that of XF, and can also hit other beys easier because of its slower movement, instead of just moving around the stadium and stop spinning just after a short period of time. You may say sliding shoot can solve this problem, but it cannot as XF is too wide and lacks grip. The bey will just move around on the outer part of the stadium right after the sliding shoot, and also because of the heaviness of Diablo. However X:D scrapes the floor too much in S and its also a mediocre bottom. It is a translucent light purple in colour. Overall, this is a mediocre bottom with no real use.

Attack: 3 - Defense: 2 - Stamina: 2
