Critical Hit is one of Agent Unknown's Flame Sword moves.
This move involves Agent Unknown standing in place while spinning the Flame Sword in a backwards arc around him with two hands.
It then flashes with light before Agent Unknown swings his sword violently downwards, creating a massive fiery explosion in front of him before he sheaths his sword.
It can sometimes give enemies a one-hit skill, hence the name Critical Hit.
- This is one of the more powerful moves of the Flame Sword, but not the strongest.
