As we all know, eons ago, Arch Angel's neurotoxin stuns were able to interrupt opponents specials. Due to how powerful this mechanic is, kabam made it not interrupt specials anymore. However, today in AW, I learned that if the stun triggers the exact same time the opponent throws a special, then their special will get interrupted.
