Lucas

"Next time, tell me before you go do anything stupid, okay?"

- Lucas, after Barbarian King is turned into GLaDOS.

is a character introduced in the room of Terraria. He's a ranger who hails from the world of Terraria, but ended up getting kidnapped by Lihzahrds at one point in his life. He specializes in guns and bows. He was made by Trash Snail.

History
He was originally a very powerful and well-respected Ranger in the Terraria room, and even managed to kill the Moon Lord one time. However, when he was least expecting it, he got kidnapped by Lihzahrds. This resulted in him getting trapped in the Golem's temple for a long time, where he suffered from isolation and starvation. It wasn't until a much longer time later before we was saved by Me, Duck, Barbarian King, King Slime and the recently-appeared Mewtwo. He then realized that the Moon Lord was still alive, so he told the gang to take out the cultists, the pillars, and then the Moon Lord himself. After that, he joined the gang to help them through the later locked rooms. When he got to The Room of Mario Kart, he met the Mysterious Figure for the first time. After his disappearance, Lucas was destined to find out just who the mysterious figure is.

When the gang got to The Room of Undertale, Lucas was planning to go full-Pacifist, and spared every monster he encountered. However, this ended when the gang killed Toriel. He was so disgusted with everyone that he sat back at the Ruins, refusing to follow them ever again. Later, the mysterious figure showed up again, and encouraged him to try and help the gang out, as they were about to fight Papyrus. This did not keep up, as Me teleported everyone to the end of the room, where he met back up with everyone. He wasn't there for GLaDOS to back-up his soul, so he was still vulnerable to Flowey the Flower at the time, worrying everyone, as if he got killed, Flowey would have 7 human SOULs and become undefeatable. During the battle with Omega Flowey, he almost got crushed by him, but Barbarian King managed to save him in time. After the battle, he got into a pokémon battle with Sans the Skeleton and Papyrus. He ended up winning, as despite the fact that the skeletons had more powerful pokémon, he had more pokémon than them (Having four, while they had one each).

Lucas then ended up meeting his future self, and ended up being filled with temporal confusion. He started to ask him questions, and learned that he will soon know who the mysterious figure is. During the battle against Necrola's Killer Robots, he got intoxicated by GLaDOS' neurotoxins, but ended up being cured of it, and gained an immunity to it, explaining why his future self had the immunity.

Abilities and Weapons

 * Phantasm: His most powerful bow. Comboed with Holy Arrows, it shoots arrows at the foes and rains stars on them. It's extremely powerful.
 * Cute Fishron: He can summon a mount that can fly and becomes much faster when wet.
 * Healing: He's able to heal a target, but it is unknown how he does so. He so far only did so to try to keep Toriel alive.
 * Neurotoxin Immunity: He's immune to GLaDOS' neurotoxins.

Pokémon

 * Lucas' Zangoose: His main pokémon. Not as strong as other options, but his Zangoose has been with him from the start, and rarely ever lets him down. So far, he has been showcased in The Room of Undertale when others were showcasing their pokémon, and during his battle against Papyrus and Sans, where he managed to take out Papyrus' Victini before going down to a Hyper Beam from Sans' Genesect.
 * Lucas' Typhlosion: Another pokémon that's been with him from the start. Typhlosion has, so far, only been seen in the battle against Papyrus and Sans, where he took out Sans' Genesect while it was recharging from a Hyper Beam via an Eruption, winning Lucas the battle.
 * Lucas' Gigalith: A shiny Gigalith. She didn't participate in the battle against Papyrus and Sans, and was only showcased earlier in the room.

Relationships

 * Barbarian King: Best friends. They act to each other like brothers. They like to pick on each other, but it's very clear that they both love and respect each other, especially since the latter saved the former from his life as a slave to the Golem. While their friendship did become a little harsher after several events in The Room of Undertale (Most notably Barbarian King helping in killing Toriel), they still deeply respect each other, as shown when Barbarian King tried to save him from getting crushed by Omega Flowey.
 * Flowey the Flower: Lucas is HORRIFIED of Flowey. Before Flowey even introduced himself to Lucas, he screamed at the sight of him, as he immediately knew his true colors. Generally, when he appears, Lucas keeps his distance. Before the battle against Omega Flowey, Lucas believed that Flowey should be terminated for his actions. However, he was unable to do that because everyone else wanted to spare him. After the battle, Lucas was so tired that he decided to let him go. After Flowey was killed, Lucas still fears that he could return, as he has the ability to reset and SAVE.
 * Mysterious Figure: Lucas is very dedicated to finding out who the figure truly is. Sadly for him, however, this usually ends in failure. The Mysterious Figure disappears before Lucas can ask him anything about him. He feels that the figure cannot hide his identity forever.
 * Script: Lucas deeply despises Script, since he feels that he ruins the fun for everyone with his stepping ability. He especially started to lose respect for him after cheating as Mario Kart so that he'd always hit first place. He constantly tries to think of ways to nullify his ability.
 * Papyrus: Papyrus is Lucas's favorite Undertale character, and he very much likes him in the locked rooms. Unlike most other people, Lucas actually enjoys his cooking, despite normally not liking spaghetti. When he was told by the mysterious figure that the gang was going to fight him, he charged to make sure that he wasn't killed like Toriel was. This technically ended in success, as Me teleported everyone to the end of the room before the gang could even get to Papyrus.
 * GLaDOS: While Lucas does not dislike her, his opinion on her is quite shaky. He agrees that she is important to the gang, but he feels that she's somewhat annoying, mostly because of the punch incident and her causing him pain after transferring his SOUL.
 * Most other people in the locked rooms: He likes most others, but isn't exactly friends with them yet. However, he wishes to know everyone well.

Trivia
