PK Thunder

The PK Thunder (Japanese: PK, PK Sandaa) is Ness and Lucas's up-B attack. When used, it creates a stream of lightning whose direction can be controlled using the control stick. It does around 8% damage and has the interesting effect of knocking the opponent in a direction opposite that of the lighting's direction; in other words, the thunder knocks the opponent in the direction that it was coming from. However, using the PK Thunder will result in Ness not being able to move or defend, seeing as the control stick is being used to move the PK Thunder.

The PK Thunder has many interesting properties. If the tail, rather than the head, of the PK Thunder hits the opponent, it will deal less damage and stun the opponent less, but also will continue flying around. This is known as a tail whip. If Ness is hit while using the PK Thunder, the thunder will cease to be in his control and will travel in a straight path until it expires.

The uncontrolled thunder can hit anybody, not just Ness's opponents. This means that one can actually use the PK Thunder as a barrier, using the tail to intentionally block oneself from flying off the screen after being hit. This is called a PK Thunder Barrier.

If Ness hits himself with the PK Thunder, he will be launched as a human projectile. This tactic is known as the PK Thunder2.

PK Thunder 2
Term used for hitting yourself with your own PK Thunder while you still have control over it. The Japanese developers called this move PK Jibaku (PK). The word jibaku means to be confined or encompassed by one's own words and actions.

This technique can be used by Ness and Lucas. Doing so will transform Ness or Lucas into a human projectile, which will move in different directions depending on what part of the body is hit. If the player makes contact with the opponent, he will deal a good amount of damage and knockback, although the SSB version is considerably stronger than the SSBM equivalent.

The PK Thunder2 is also Ness and Lucas' main method of recovery, given that it launches them fairly far in a straight direction. It is not easy to pull of this recovery, however.
