The 2.10.1 update has been added into the game to fix the above glitches.And the same can be said if the AI uses their specials, if you block, your character has a chance to deals UNBLOCKABLE damage as well (still need to be tested furthermore). Additionally, if the characters as said above use their UNBLOCKABLE special(s) on the AI opponent, upon the AI block, and after the special is finished, the Blocked AI can deal UNBLOCKABLE basic attacks and/or specials for a limited time.So far, Deathstroke/Arkham Origins, Superman/Godfall, Superman/Regime, all versions of Harley Quinn's bomb for her SP2, along with Harley Quinn/Arkham's passive (won't let her Arkham teammates deals unblockable on their SP2), Ares/Prime's SP2 can be blocked normally (and the block-disable passive would still work, and furthermore, if the opponent that has it tags in, whichever character that tags in next will have that passive) and Killer Frost/Prime are confirmed to have this. This is confirmed to be a glitch, and instead, if the opponent blocks, it will be dealt as regular damage when they blocked. Characters with unblockable special(s) are unable to deal UNBLOCKABLE DAMAGE (either as according to their passive or in their specials' descriptions).Challenge repeats of Superman/Dawn of Justice, Wonder Woman/Dawn of Justice, Black Adam/Kahndaq, Sinestro/Antimatter, Green Lantern/Red Lantern Hal Jordan, Lobo/Bounty Hunter, and Darkseid/Apokolips.
