PK Starstorm (Japanese: PKスターストーム PK Starstorm), known as PSI Starstorm in EarthBound, is a PSI attack, introduced in EarthBound. It is a powerful attack, only taught manually to those who have earned it. In EarthBound it is learned by Poo and has the levels α and Ω. In Mother 3, Kumatora learns this move, it only has one level of power unlike in EarthBound.


Described as "shaking off the stars", the user sends a shower of shooting stars at the opponent. The attack damages every enemy on screen and cannot be avoided. A side affect with the attack is that it has the possibility of decreasing the enemy's PSI Shield strength by 1. In both games PK Starstorm is among the strongest PSI attacks in the games, In EarthBound it is only rivaled by PSI Rockin Ω and PK Freeze Ω, and in Mother 3 it is rivaled only by PK Love Ω.

In both games, PK Starstorm can only be learned at a specific point in the story.

PK Starstorm is not affected by elemental weaknesses.

Poo leaves the party temporarily with the Star Master to learn PK Starstorm α after they exit the pyramid in southern Scaraba, and later comes back with his new power in the middle of a fight against Master Barf in Deep Darkness. He gains PK Starstorm Ω at the Cave of the Past shortly before the party is turned into robots and transferred back in time to defeat Giygas.

PK Starstorm becomes Ness's and Lucas's final smash starting in Super Smash Bros. Brawl. According to trophy information in this game, Ness was taught the move by Poo, and Lucas learned it from Kumatora. The move has many meteors falling in random areas of the screen, dealing a significant amount of damage to those hit. Ness and Lucas's variants function slightly differently from each others': for Ness's version the stars are blue and fall angled outwards. For Lucas's version the stars are red and fall mostly straight down, but slightly inwards.

Both Ness and Lucas have PK Starstorm as their final smash in Super Smash Bros. for Nintendo 3DS and Wii U as well, only now they can have control over the where the meteors fall, albeit they are concentrated into a smaller area now.

In Super Smash Bros. Ultimate, PK Starstorm is once again Ness and Lucas's final smash, this time combining elements from its two previous appearances. Ness stars spawn above him and are angled outwardly, the player can slightly control where they fall akin to the previous game, albeit to a much lesser extent. Lucas's instead spawn offset of him from the left and right, and like Ness, the player can control where they fall. In terms of gameplay differences, Ness's version covers more of the stage and has more potential to hit multiple opponents akin to Brawl, whereas Lucas's has greater control over where they fall akin to for Nintendo 3DS / Wii U.

Additionally, in Ultimate, Paula and Poo appear to assist Ness when PK Starstorm is used, while Kumatora and Boney assist Lucas. Also when the move is used, stars that appear as they did in EarthBound and Mother 3 can be seen. The background will also change when the move is used and is different depending on the character: for Ness's variant the background changes to that of when the Sound Stone is used in EarthBound, and for Lucas, the background changes to that of the final battle against the Masked Man, which was also used during the fight against the Evil Mani Mani in EarthBound. All of these changes are purely aesthetic and have no effect on the gameplay.

  • Kumatora's PK Starstorm is weaker than Poo's PSI Starstorm Ω, even though she needs more PP to use it.
  • In the original Super Smash Bros., Ness has an unused voice clip where he shouts "PK STARSTORM!" in a similar manner to when he uses it as a Final Smash in later games. Final Smashes were planned to be in the game, but were scrapped due to hardware limitations.
