Lucas

Lucas is the protagonist of the Japan-only game Mother 3 from the Mother series. In this game, he lived with his twin brother Claus and his parents Hinawa and Flint, in Tazmily village located in the Nowhere Islands. Soon in the game, his mother is killed and his brother is lost, because of the Pig Mask Army, led by Porky.

Super Smash Bros. Brawl
Lucas appears in Super Smash Bros. Brawl as a playable character, one of the two representatives from the EarthBound series. Lucas's special moveset is almost exactly like Ness's from the previous games, but with a few minor tweaks. His neutral special is PK Freeze, which sends up a snowflake that freezes opponents caught in its blast when Lucas sets it off. His side special is PK Fire, which sends out a lightning bolt directly forward that explodes when it hits. His down special is PSI Magnet, which sets up a barrier in front of himself that absorbs projectiles to restore damage and attack when the barrier is dropped. His up special is PK Thunder, which sends out a ball of lightning that can attack opponents and propel Lucas forward. His Final Smash, also shared with Ness, is PK Starstorm, which sends groups of stars raining down on the stage in an inward direction. Lucas does not actually learn any of his special moves in Mother 3; rather, they are all learned by Kumatora.

All his normal moves and Smash Attacks are completely different, with the exception of his side smash attack which operates similarly to Ness's bat, though Lucas uses a stick instead. In addition, Lucas's grab is the Rope Snake, a weapon used by Duster which also acts as a tether recovery. His home stage is New Pork City.

Lucas was originally meant to replace Ness in Super Smash Bros. Melee. However, Mother 3 for the Nintendo 64DD, then unofficially known in America as EarthBound 64, was cancelled, to be later revived for the Game Boy Advance in 2003 and released in 2006, only in Japan.

Role in the Subspace Emissary
In the Subspace Emissary, Lucas is shown as a weak, shy and timid figure, similarly to his appearance in the beginning of Mother 3.

Lucas first appears alone in the Ruined Zoo. He is attacked by The Pig King Statue, but Ness arrives to save him. They proceed to fight Porky, but then Wario arrives with his Dark Cannon and attempts to hit Ness with it. Ness dodges his attacks, so Wario tries to attack Lucas instead. Lucas doesn't move out of the way, so Ness ends up taking the hit himself. Lucas, scared, runs away and meets the Pokémon Trainer, and they join to fight the Subspace Army, as Lucas cannot forget what Wario had done to Ness.

Outside the Ruins, the Pokémon Trainer decides to capture a Charizard that flew by. Before entering them, however, they are ambushed by Wario. They defeat him, but Lucas becomes disappointed that Wario doesn't have Ness with him anymore. After capturing Charizard and an Ivysaur inside the Ruins, Lucas and the Pokémon Trainer reach the Ruined Hall, where they are attacked by Galleom. After defeating him, Galleom takes them and starts flying into the air, with a Subspace Bomb in his head about to go off. Lucas frees himself and the Pokémon Trainer, and they are then saved by Meta Knight, whose team they then join.

At the Glacial Peak, Meta Knight leaves them, but they are then joined by the Ice Climbers as the Subspace Army is sent out to attack them. Mario, Link, Yoshi, Kirby and Pit then appear and defeated the enemies. Soon, the other remaining heroes show up and they enter Subspace together. Unfortunately, Lucas and the others were defeated by Tabuu. But then Lucas is saved by King Dedede, who had revived Ness and Luigi with badges. All of the revived heroes then fight and defeat Tabuu.

Super Smash Bros. for Nintendo 3DS / Wii U
Lucas has been released as the second downloadable playable character after Mewtwo in Super Smash Bros. for Nintendo 3DS / Wii U, released on June 14, 2015. Lucas's moveset is mostly unchanged from the previous game, though his Final Smash PK Starstorm has been altered to be similar to Ness's version. He also has a new alternate color with black hair and a sprite of the Masked Man from Mother 3 on his T-Shirt. Nintendo has confirmed that Lucas will be receiving an amiibo as well.

Bios

 * Instruction manual: A youth with pronounced psychic powers. His PK-based attacks hit hard.
 * Website: The youth with the psychic powers has appeared—it’s Lucas! He makes his anticipated debut from the Japan-only release MOTHER 3.
 * While he is timid in nature, he fights splendidly. Is it possible he can surpass even Ness?!

Snake's codec

 * Mei Ling: I see you're fighting Lucas, Snake.
 * Snake: Lucas?
 * Mei Ling: That boy has PSI powers, which he can use for different kinds of attacks. But the poor little guy's had such a hard life. His mother was killed when he was young, and he was separated from his brother. After that, he faced all kinds of senseless hardships, and he slowly grew stronger.
 * Snake: Senseless hardships--yeah, I had a lot of those, too. The question is how you translate those hardships into a better future.
 * Mei Ling: ...Mmm. Well, I hope things turn out OK for him.

Palutena's Guidance
The following dialogue applies also to Mewtwo, Roy, and Ryu, all DLC characters like Lucas.


 * Pit: Who is THAT?
 * Palutena: I have no data on this fighter. I can't believe it!
 * Viridi: It must be an intruder from another dimension!
 * Pit: Whoever it is, the goal remains the same: to fight and win!

Trivia

 * One of Lucas's alternate skins makes him look like his twin brother, Claus.
 * Lucas' and Ness' victory theme is a portion of the title theme for the first Mother game.
 * Though Lucas's name was designed with the French pronunciation in mind (with the 's' at the end silent), the English dub of Super Smash Bros. Brawl still pronounces it.
 * While Lucas's Final Smash trophy explains that Kumatora taught Lucas PK Starstorm, she obviously also must have taught him PK Fire, Freeze, and Thunder, along with PSI Magnet, since only she could use that PSI in Mother 3.
