When the audience needs to be shown how physically dangerous an enemy is, the creators invoke The Worf Effect, or maybe they throw a Sacrificial Lamb (or worse, a Sacrificial Lion) in the path of the bad guy. But when the producers don't feel like killing one of their characters yet, but still need to show the audience just how dangerous the situation is, they often resort to breaking the badass by having the hardest, coldest, roughest, toughest, most jaded and violent, seen-it-all character become shocked out of their wits by it. Expect Oh Crap or Mass "Oh Crap" reactions.
