Muscle Control: Deltoid Roll
Rarity: Unique
Granted that rolling is a control type performance always rarer and harder than the bounce, then rolling one of the hardest muscles to gain isolated control over is admittedly extremely rare. So far, only one performer has demonstrated this control.
D is the only performer who has been able to perform deltoid roll.
Unsurprisingly, he was a performer of total six muscle groups (pecs, biceps, triceps, quadriceps, calves and deltoids), the majority of them incredibly rare, projecting astonishing muscle control over his entire body.
