Much like The Worf Effect, The Worf Barrage is that attack that's supposedly all-powerful, ultra-destructive, and super-awesome, but in reality only serves as the "that" in No One Could Survive That, because they just did.
This is the thing that proves how resilient or Badass the Big Bad or Monster of the Week is. Almost always produces large amounts of smoke or debris, allowing the hero to think the enemy was killed, before his shielded silhouette starts to show through. At least you hope it's shielded...
The trope is essentially an inversion of The Worf Effect — that trope shows how powerful a new force is by its defeating the strongest cast member, while this trope shows how powerful a new force is by a cast member failing to defeat it. Might prompt a What the Hell Are You? moment. Compare with It Only Works Once, So Last Season, Punch! Punch! Punch! Uh Oh... and No Sell. Contrast Unblockable Attack. If the attack wouldn't do anything to anybody, it's more likely to be a Fake Special Attack. Often followed by a retaliatory No-Holds-Barred Beatdown.
