PK Starstorm

PK Starstorm (ＰＫスターストーム, Pīkei Sutāsutōmu) is ' Final Smash in Super Smash Flash 2. Ness uses his PSI powers to summon a barrage of psychic comets that rain from the sky, which can do 20% of damage if they connect with an opponent. The comets fly down in a fan shape, similar to in Super Smash Bros. Brawl.

Origin
The origin of PK Starstorm comes from the game Earthbound, known in Japan as Mother 2, where it is actually learned by Ness' companion Poo, a prince from Dalaam and not Ness himself. However, in the description of the PK Starstorm for Ness in Brawl, it is hinted Poo teaches Ness this attack.

Trivia

 * In earlier versions of the Super Smash Flash 2 Demo, the comets of PK Starstorm would alternate from one diagonal angle to another and would remain of the stage for a longer period of time.
