PK Fire (ＰＫファイヤー) is Ness's side special move in Super Smash Flash 2. Ness releases a bolt of fire from his hands forwards. In the air, he shoots the bolt diagonally downwards (like Ki Blasts). If the bolt hits the opponent or an attackable item, it turns into a pillar of flames, making the target take damage for 2 or 3 seconds along with dealing a maximum damage of 22% if the opponent is stuck for the entire duration of the attack. It can be a damage racker as it damages opponents quickly. If it is landed on an aerial opponent, the move meteor smashes the opponent after the pillar of fire disappears. The pillar can drag the opponent down. If it hits an opponent's shield, it bursts into the pillar of flames causing continuous shield damage.
