PSI Rockin originates from EarthBound, released as Mother 2 in Japan in 1994 and on SNES in North America in 1995. It is Ness's signature offensive PSI ability, named after the player's favourite thing, with Rockin as the default. The attack's trippy visuals and sound became iconic among RPG fans, helped by EarthBound's cult following and Ness's later appearances in Super Smash Bros. Online, the clip survives on soundboards and in fan edits as shorthand for a powerful, mind-bending psychic blast from the 16-bit era.
