Paralyzing Your Opponent First

A useful condition in Dragon Ball: Sparking Zero is Paralyze. Landing an attack with this condition will leave the opponent in a defenseless state and stop their movement for three seconds. That’s more than enough time to throw out a rush super.
You can find quite a few characters with unique moves that paralyze the enemy. Examples include Majin Buu’s Paralyze Beam skill, and most versions of Frieza having the Psychokinesis skill. If the enemy is hunched over with purple electric sparks coming off them, then it worked.
