Ness originates from the highly acclaimed game Earthbound or Mother 3 in Japan. Ness's first appearance in the Smash Brothers Series was in the original Super Smash Brothers for N64, making him one of the 12 original characters still in the series!
Also from the Earthbound series comes Lucas! Originally introduced in Super Smash Brothers Brawl, Lucas quickly became a fan favorite. Left out from the roster of Super Smash Brothers for 3DS and WiiU, fans were outraged. Luckily their sounds of sorrow were heard, as Lucas is now a purchasable DLC for the game! The Classic stage Onett is another staple from the Earthbound series that has past the test of time. This stage features hazards like cars driving by which are able to hit characters and cause tons of damage. Also this stage was one of a kind as it had no downward out of bounds limits.
