Defense-S is a Performance Tip released as part of the Burst System as well as the SlingShock System. It debuted in western countries with the release of the SlingShock Single Pack Flame-X Diomedes D4 8 Defense-S.
Defense-S, as its name implies, is a SlingShock Performance Tip based off of Defense. However, unlike the original Defense, Defense-S' ball tip is significantly taller and it features two tabs on either side that are connected to the ball tip, which is meant for the activation of the Performance Tip's "SlingShock Mode". As a part of the SlingShock System, Defense-S can be manually altered to switch between "Battle Ring Mode" and "SlingShock Mode"; in this case, by sliding the tabs to the other side, and then pushing both tabs downwards, and vice-versa.
