Lucas (リュカ, Ryuka) is a playable character in Super Smash Bros. Brawl. He is the first EarthBound newcomer since the original Super Smash Bros.. Lucas is the main character of Mother 3, the Japan-only sequel to EarthBound. Lucas' special moves are similar to Ness', but his physical attacks are almost all completely different. Lucas relies on his PSI powers far more than Ness, using them for all but his forward smash, up aerial, down tilt, and standard combo attacks.
Lucas uses Duster's Rope Snake from Mother 3 to perform a tether recovery. The Rope Snake is also a taunt, where Lucas looks at the snake and argues with it. Lucas also utilizes Duster's Rope Snake for his grabs, giving him a ranged grab, much like Link, Toon Link, Samus, and Olimar. Like Ness, all of his special moves, as well as his Final Smash, derive from in-game attacks that are instead learned by another character, in his case, Kumatora, not Lucas himself.
Lucas currently ranks 30th on the tier list at the very bottom of Lower-Mid tier and the lowest rank of the newcomers. Lucas possesses above average speed and mobility, as well as powerful and effective finishers, a great and versatile recovery with several options, fast attacks, and multiple attacks that can setup additional blows effectively. However, Lucas possesses a subpar aerial game with mediocre aerial attacks, no reliable finisher outside his smash attacks (limiting his versatility in being able to finish off an opponent), and a rather poor grab and throw game, possessing a not so far reaching tether grab and lacking any effective setup throws outside of low precents. His most major flaw though, which is often cited as the reason for his low tier placement, is the 10 additional frames of lag he suffers when grab released on the ground, similar to his semi-clone, Ness. This makes him vulnerable to grab release followups from nearly every character, as well as a 0-death grab release and an infinite grab release from Marth and Donkey Kong respectively. As a result, Lucas has three terrible matchups due to grab release issues from Sheik, Marth and Donkey Kong, giving him several hard counters, and poor tournament results.
Lucas is a character with some slow but strong attacks that have large hitboxes, and average dash speed. It should be noted that Lucas's aerial range (like many of his moves) is quite low, his forward and backward aerials having low range, and his down aerial having bad horizontal range. On the upside, his aerials are generally quick, and his back and down aerials can meteor smash opponents. Note that both of his two aerial meteor smashes are hard to hit with in the fact that they can only meteor smash an enemy downwards with a certain "spot" of the attacks (tip of his foot for the back aerial, 4th and final kick for his down aerial, which is easier to land but weaker).
His smashes are very strong: His up smash can be charged for massive damage and vertical knockback, as well as having a gigantic hitbox, his forward smash is a strong and reasonably quick smash attack that also reflects projectiles (like Ness' forward smash), and his down smash is very strong and can hit three times, but has a bit of startup lag. Two of his smash attacks (up smash and down smash) tend to have enough ending lag to be easily punished in most situations, leaving him using only his forward smash for easy on-stage kills, which becomes too predictable for KO use. However, his down-smash is among the highest damaging in the game, alongside Ice Climbers, but all three hits would only typically connect if the opponent has some form of knockback resistance or is on the platform in Smashville and if an opponent is vulnerable, up smash makes a very easy and quick KO.
Two of his special moves can be “controlled”, PK Freeze and PK Thunder. This means that these attacks both leave Lucas very vulnerable because he can't move or attack when controlling these projectiles, except for using the projectiles themselves to defend him. PK Thunder is Lucas’ main recovery move. If it hits Lucas, it will shoot him in an angle depending on the part of Lucas's body which it hits, and will deal a large amount of damage if most or all of its hits connect. It also deals reasonable knockback, but is a bad approach. PK Thunder normally goes through enemies and objects, but it can still be interrupted by certain attacks (hurting PK Thunder Recovery). PK Freeze can be controlled from side to side and can freeze opponents and do a good amount of damage if "charged", but the vertical nature of its knockback limits its use. His side special, PK Fire, is a single hit move that pushes Lucas back a little, making it great for Wavebouncing. It can also be used to Zap Jump, which gives Lucas’s recovery a substantial boost. His down special, PSI Magnet, can absorb energy based projectiles, such as Ray Gun bullets, Fire Breath and even Pikachu's Thunder, and if it used right after PK Fire, can push him back even further called the Magnet Pull, giving him a great horizontal recovery. His grab range is great and is far longer than Ness's range since it's a tether, but it is quite laggy if missed, however his Pivot Grab is much less laggy. His throws are also powerful with good KO potential for a throw, most notably Down Throw. In addition, his second jump is the 3rd highest in the game, falling a little shy of Ness who is also exceeded by Yoshi. As stated above, the jump can be significantly lengthened by performing a PK Fire 1 frame after a midair jump has been inputted.
Lucas is known for having a good lock setup; if a grounded opponent is hit with the last two hits of Down Aerial, it becomes incredibly hard to tech the last hit, allowing for a quick Down tilt lock, and then a finisher, which is almost always an immediate Forward smash, the most common, or a charged Up smash, both are guaranteed if performed right but the Forward smash is easier and has almost no risk of failure. This adds to Lucas' limited KO possibilities.
Overall, Lucas benefits from a high double-jump, powerful and quick Forward smash, high damaging and powerful up and down smashes, long range grabs and strong throws, the best pummel damage-wise, a good recovery move in PK Thunder 2, which when used correctly, gives good recovery distance and a very versatile angle of recovery, and advanced techniques such as Magnet Pull, Zap Jump, Z-Air Jump, Wavezap and Thundersliding. However, being 0-death grab released by Marth and infinited by Donkey Kong is a major flaw in his game. He, like Ness, suffers from 10 additional frames of lag when he escapes from grabs, enough to be dash re-grabbed by many characters (although the timing is strict) or open for certain attacks (some, but not many, characters can easily followup with a strong attack, especially Marth, Donkey Kong, and Wario, among others.) He is fairly floaty, and his smash attacks are slow. However he has a hard to gimp recovery and is better than Ness in this aspect, since his PK Thunder can travel through opponents, requires less space, and he has many more options, including Zap Jump, Magnet Pull, and zair or zair jump (done by buffering a jump after an aerial's lag time, then air dodging as soon as possible and using the zair immediately after).

 Role in The Subspace Emissary
Lucas is seen walking alone in an abandoned zoo, until several Primids show up. Then, suddenly, the gigantic Porky Statue appears and chases after Lucas. Lucas runs from it, until he gets caught in a snag and is about to be crushed when Ness comes to his rescue by attacking the statue with a PK Thunder. Ness blows up the Porky Statue with his PK Flash, which reveals Porky Minch himself (based on his Mother 3 appearance). Ness and Lucas defeat him, but no sooner do they do so when Wario shows up and attempts to shoot Ness with his Dark Cannon. Ness dodges each time, so Wario eventually aims at Lucas and shoots. Ness pushes Lucas out of the way and gets turned into a trophy himself. Terrified, Lucas runs away as Wario cackles in the rain.
Later on, Lucas runs into the Pokémon Trainer as more Primids show up. After they are defeated, the Pokémon Trainer leaves, but Lucas decides to join him after remembering what happened to Ness. Lucas and the Trainer encounter and defeat Wario in the desert wastelands outside of an abandoned temple, but Lucas gets depressed when Ness is still nowhere to be seen. Along the way, the Pokémon Trainer catches Ivysaur and Charizard. After Charizard is caught, Galleom falls into the ruins, having been knocked down there by Marth, Meta Knight, and Ike. A battle ensues between Lucas, the Pokémon Trainer, and Galleom.
After the battle, Galleom grabs Lucas and the Pokémon Trainer, jumping high into the sky and out of the ruins. Galleom then attempts to detonate a Subspace Bomb as a last-ditch effort. Lucas, finally gaining his courage, uses PK Thunder to sever Galleom's arm, causing the two to plummet to the ground. Just before they hit the bottom, Meta Knight grabs the two and takes them to Marth and Ike. When there, Lucas shakes hands with the Trainer as a sign of their friendship.
Lucas and the other heroes confront the Subspace Gunship, and then journey into subspace to battle Tabuu. Lucas is defeated by Tabuu's Off Wave, but later revived by Ness and his companions. He accompanies the heroes into the Great Maze, and can be used to defeat Tabuu at the final battle.
 Playable appearances
 Exclusive stickers
Lucas can use any sticker that has a PK attack bonus, similar to Ness, which covers all but his forward smash, down tilt and up aerial. He can also use ice, fire, and electric attack bonuses for his special moves, though Indirect Attack would likely be more effective as using three stickers separately would be inefficient. Lucas's physical attacks are mainly composed of Leg attacks, though his forward tilt is Arm, up aerial is Head and forward smash is Weapon.
Lucas's trophy is obtained by clearing Classic Mode with Lucas.
