Opponents affected by disable debuffs shouldn't be able to use their blockbusters, specials, and tag ins until the debuff duration runs out. However, I've noticed opponents can sometimes override the disable effects and still manage to use their specials and tag ins. As you can see in the image above, Peacock was just inflicted with all 3 disable debuffs from my Parasoul but Peacock somehow could still use her taunt special and the Immunity removed disable blockbusters and tag ins but the disable specials one is still active (and obviously not working). When the disable tag in one doesn't work, something weird and funny happens: the opponent will activate their tag out animation but they'd tag themselves in again instead of another teammate. Here you can see the disable blockbusters effect is active but clearly doesn't work.
