This papercraft is Ness, a 13 year old boy from Onett, and the main character of the cult classic SNES RPG EarthBound, the most successful game in the Mother/EarthBound franchise, the paper model was created by Paperlegend.
Ness appears as the sole representative of both the game and the series in Super Smash Bros. and Super Smash Bros. Melee. He appears in Super Smash Bros. Brawl alongside fellow Mother representative, Lucas, who hails from Mother 3.
Despite being buffed from Melee to Brawl, Ness is currently ranked 27th on the tier list. His unsafe recovery, unusually long grab release animation, and below-average match-ups have prevented him from reaching high tier. However, his powerful KO moves, good comboing ability, and powerful throws have gotten him into the F tier. [Source: ssbwiki]
