Jeff

Jeff is one of the main heroes in EarthBound and the son of the scientist Dr. Andonuts. In EarthBound, whereas the rest of Ness's party can utilize PSI attacks, Jeff's attacks use guns and other gadgets, such as various types of bottle rockets and stat-altering devices.

In the Super Smash Bros. series, Jeff first appears in Super Smash Bros. Melee as a trophy, along with Ness's other companions, Paula and Poo. Starting with Super Smash Bros. Brawl, Jeff appears as an Assist Trophy. If summoned, Jeff prepares a set of five bottle rockets and launches them; the rockets home in on opponents. There are always four small bottle rockets followed by a big bottle rocket at the end. Occasionally, Jeff may set up a second round of bottle rockets to launch at foes.

In Super Smash Bros. Brawl, there is also a sticker of Jeff, which depicts his EarthBound artwork. It can only be equipped by Ness and Lucas. When equipped, it gives a bonus of +24 to all of their attacks. There game also features a trophy of Jeff.

Jeff returns in Super Smash Bros. for Nintendo 3DS / Wii U as a trophy. In Super Smash Bros. for Wii U, his trophy is unlocked by playing as Ness in Stage 3 of Solo Target Blast and getting a score of at least 200,000.

In Super Smash Bros. Ultimate, there is a spirit of Jeff. Like his sticker from Super Smash Bros. Brawl, Jeff's spirit depicts his artwork from EarthBound.
