Black Canary can perform screams, or Canary Cry, by pressing
. The move is charged depending how long you wait, and if the meter is filled, a Level 3 cry is performed.
Set up a Versus or Single Fight (VE difficulty) and pick Black Canary plus any opponent. Then, beat your opponent down until their health is very low, 10% or less but not defeated, then hold the
button until you perform the Level 3 scream. If they KO after you perform it, the trophy will unlock.
