Lucas

Lucas is the main Assist PSI user of the party because he learns all versions of Lifeup, while Kumatora only goes up to Beta. He also learns all versions of Healing, while Kumatora only learns Alpha. He also has Refresh, which restores about 10% of the target's maximum HP each turn. His unique PSI attack is PK Love, which does anywhere from 100 to 800 damage, depending on what level of power is used. He also learns Shield, Counter, PSI Shield, PSI Counter, Offense Up, and Defense Up. In Chapter 5, he learnsPK Flash. In Super Smash Bros. Brawl, however, he can use PK Fire, PK Freeze, PK Thunder, PSI Magnet, and PK Starstorm.

Throughout the remaining chapters, Lucas is described as becoming "more and more gallant." Nippolyte claims that Lucas has "grown so strong that Flint doesn't need to worry anymore", and has "grown up to be a truly good lad."

Additionally, the coffee sequence in Saturn Valley states that he has grown strong for those he otherwise would be unable to help. Although glimpses of his previous shy self still shine through, Lucas has toughed through the odds and has become a kind, resilient boy, and this remains true up to the final moments of the game.

Initially, Lucas is described as being a gentle boy, and can be seen as an antithesis to his more energetic twin, Claus.

He is said to be a bit coddled and seems to be slightly nervous. Despite this, he doesn't shy away from a bit of fun and play with his family. He is said to have been raised honest, hurriedly telling Alec the truth about Claus' disappearance when prompted. Additionally, he seems to be a bit of a late riser.

Following the sudden death of Hinawa and disappearance of Claus in Chapter 1, Lucas gains a reputation of being a 'crybaby'. He is visibly distraught, and struggles to cope with the losses that he's so abruptly had to endure. Duster states that "[Lucas'] poor little heart seems like it's about to break in two." He becomes a bit of a shut-in, rarely seeming to leave his house following the events at Hinawa's funeral.

During this time of grief, Lucas seems to struggle with feelings of survivor's guilt. (This is further supported by his hallucinations within Tanetane Island.) In Chapter 2, he's seen unable to get to sleep despite his efforts, and thinking that he should have gone with Claus. All of this, accompanied with the steady transformation of his hometown, forces Lucas to mature rather quickly for someone his age.

Three years later, Lucas is strong, determined, and resourceful. He cares deeply for his friends and his fellow townsfolk. He is somewhat rebellious with his refusal to buy a Happy Box and give in to Tazmily's modernization. Because of this, though, his local reputation seems to be less than favorable, and he is treated rather crudely - but Lucas doesn't let this get the better of him. After meeting with Kumatora in Chapter 4, Lucas expresses that he wishes to grow stronger. Following this and teaming up with Kumatora and Duster, he bravely pursues any task that he is given, no matter how frightening or daunting it may be.

Lucas has blonde hair and black eyes, occasionally shown with a hint of teal. He usually wears a yellow t-shirt with red stripes, blue shorts, white socks, and orange and yellow sneakers.

Sticks are his primary weapon. He can also equip baseball bats, yo-yos, or a flail mace. His signature PSI ability, PK Love, grants him the ability to pull the Seven Needles to awaken the Dark Dragon sleeping underneath the Nowhere Islands.

Lucas is autistic. Level 1.

Boney. A brown dog. His bestest friend. Boney has always cared about Lucas, and vice versa.

The son of Flint and Hinawa and younger twin brother of Claus, Lucas is a boy who lives with his family in Tazmily Village.

Lucas is the youngest child out of Hinawa and Flint's twin brothers. His elder twin is Claus, and he is Alec's grandson.

Lucas's favourite food is omelettes.
