Name How to Unlock Picture Description
Ness Classic NessTrophy3DS.png Hailing from Onett, a small town in Eagleland, this young boy's ordinary looks hide his psychic powers. Ness fought against the evil Giygas in EarthBound, and in Smash Bros. he unleashes some of the same PSI moves. Watch out for PK Thunder, a guided attack that can also launch Ness like a rocket!
Ness (Alt.) All-Star NessEXTrophy3DS.png Ness may have psychic powers, but that doesn't mean he shies away from getting physical. His side smash packs a real punch if you hit enemies with the end of his bat, and it can even deflect projectiles! His up and down smashes also have a lot of range—Ness can land his strikes with ease!
Lucas Classic Mode LucasDLCTrophy3DS.png The younger of the twin brothers from Nowhere makes his triumphant return to the game of Smash. Hailing from the Japan-only game Mother 3, Lucas’s specialty is psychic projectile attacks. He can use these PSI attacks to do things like absorb enemy projectiles and deal supernatural damage!
Lucas (Alt.) All-Star LucasDLCEXTrophy3DS.png Lucas’s up special PK Thunder can hit enemies multiple times, but if you hit yourself with it, you can then tackle and launch opponents! Lucas’s up smash has the strongest launch power of any fighter’s up smash. The range for this attack is wide, and it’s strongest right after Lucas unleashes the attack.
Mr. Saturn Win 2 matches as Ness Mr. Saturn3DS.png Mr. Saturns are curious beings that speak their own language. They might not look it, but they're scientific geniuses! In this game, they tend to go for a stroll around the battlefield. Throwing one at an enemy won't do much damage, but Mr. Saturn will take a shield out very easily.
Franklin Badge TBA FranklinBadgeTrophy3DS.png While not the most flashy of accessories, the Franklin Badge is actually incredibly useful. When wearing it, any projectiles launched your way will be reflected harmlessly off you. There is no downside, so grab this as soon as it appears. Don't get too confident, though—the bonus doesn't last long.
Starman TBA StarmanTrophy3DS.png These alien henchmen serve Giygas, the chief villain of EarthBound. In Smash Bros., the assist trophy Starman will teleport around and fire off PSI moves like PK Beam γ or PK Beam Ω. You can defeat one summoned by an opponent, but they won't go down without a fight.
Jeff Andonuts TBA JeffAndonutsTrophy3DS.png One of the main party members in EarthBound, he attends Snow Wood Boarding School in Winters. Jeff takes after his inventor father, Dr. Andonuts, creating devices in his free time. One of these is the bottle rocket, which fires one large missile and four smaller ones. And sometimes one extra!
Devil Car TBA DevilCarTrophy3DS.png A fearsome enemy from the Mother series, this car attacks mercilessly, closing in on fighters before trying to hit them as it spins doughnuts. No, these aren't the kind you eat—they're the kind that hurt. Its exhaust fumes can cause paralysis too, so keep your distance until it's between attacks.
Magicant TBA MagicantTrophy3DS.png A magical world in Mother and Earthbound, brought to life by the memories of a certain character. In this game, Magicant is a cloud stage where giant tomatoes, metal octopuses, and even the Sky Runner may apper. Even the hulking Dungeon Man may show up. What an unusual battlefield...
Flying Man TBA FlyingManTrophy3DS.png The Flying Men are a team of five birdmen. Each time a Flying Man appears, he'll help the first person to reach him with Flying Cross Chops and Somersault Kicks. A small memorial stone will be erected for each one defeated. Once all five are gone, they're done fighting forever until the next battle.
Sky Runner TBA LilSaucerTrophy3DS.png A flying machine designed by Dr. Andonuts, it is given to Jeff to travel to Threed. It promptly crash-lands, rendering it temporarily out of service. On the Magicant stage, it can sometimes be seen floating above the clouds before it suddenly zooms back into the sky.
Dungeon Man TBA DungeonManTrophy3DS.png Thanks to Dr. Andonuts's genius, the dungeon creator Brickroad was able to become the first man-dungeon hybrid in history, complete with an ATM, pay phone, and hospital. He walks back and forth slowly in the Magicant stage, and his head can serve as a platform to ride on as you fight.
Lucas TBA LucasTrophy3DS.png Lucas used to be weak-willed, and cry all the time. However, he overcame unimaginable hardships, and must surely be out adventuring, or perhaps, he's found a partner and made a family of his own... No ... It's too soon. To fans of the MOTHER series, both Lucas and Ness will be young forever.
Porky Statue TBA PorkyStatue3DS.png A statue of Porky that Porky ordered built to honor the great exploits of Porky as acknowledged by Porky. It depicts Porky in his carefree childhood days in Onett, a comic book in one hand and a slingshot in the other. Be warned—this statue is also an incredibly tough enemy!
