The younger of twin brothers living in Tazumili Village in the Nowhere Islands. He's a kind boy who can communicate with animals, but he's shy and never really got over the tragedy that struck his mother. He fights a warped dictatorship, hunts the Seven Needles, and crosses swords with his missing brother, Klaus. In the end, the young boy with psychic PSI powers grows up.
PK Starstorm (Lucas)
Lucas's Final Smash. He pulls a large group of stars from the sky and sends them smashing down among his enemies, causing damage to one and all. In Mother 3, this move was used by Lucas's traveling companion, Princess Kumatora. As Ness learned this move from Poo, Princess Kumatora taught Lucas when he learned he would appear in Super Smash Bros. Brawl.
An average boy whose life changed when he found a meteor and an alien on a nearby mountain. The alien warned him of a future threat, and adventure ensued. He can use psychic energy known as PSI and also wields a bat and yo-yo. This brave youth gives his all to defeat the evil Giygas.
PK Starstorm (Ness)
Ness as he calls down a host of damage-dealing stars in his Final Smash. Everyone on the screen must dodge like crazy to avoid getting hurt, but that's no easy task. This attack appeared in the Mother series, but it was Poo, not Ness, who wielded it. Perhaps Poo taught Ness the secret of the attack for use in Super Smash Bros. Brawl.
A self-centered, rotten brat who lives next door to Ness. As the events of the game progress, he's rapidly led astray and becomes Giygas's right-hand man. Afterward, he goes missing in time and then reappears in the Nowhere Islands of Mother 3. He leads the Pig Mask Army invasion but is eventually defeated by Lucas and friends.
A guardian statue standing inside New Pork City that's clearly based on Porky himself. Investigate it, and the statue will turn hostile and start a battle. And it has 100,000,000 HP! It has very high stats, so you'll never win if you attack it straight-on. Thankfully, there's an item called "New Year's Eve" that can reduce its HP to 1-- then you can defeat it with ease.
Dr. Andonuts's son, who attends a boarding school in Winters. He receives a telepathic message from Paula saying that she and Ness have been captured, and he sets out to rescue them. He's Ness's age but has the knowledge of an established scientist. He repairs broken items and makes them into other things. As his IQ increases, so does the number of things he can create.
A creature from a race of unknown origin that speaks its own unique language. Some say they came from outer space, but the facts behind their appearance are wrapped in mystery. In Smash Bros., they'll wait a bit after appearing before wandering off on their own. They can be picked up and thrown at foes for minimal damage. Their shield- breaking properties are high.
A badge you can put on to gain the ability to reflect all projectiles. It has exactly the same effect as other reflectors in the game, like the one Fox uses. In EarthBound, it was used to counter Thunder attacks. The lightning bolt on the badge is proof of its capacity. Its importance and usefulness made a deep impression on players.
