Rak Wraithraiser, a C-rank Regular from the Wraithraiser species, hails from an environment solely shared with turtles. This unique upbringing ingrained a worldview where he categorizes all other beings as "turtles," irrespective of their actual form. He is a direct descendant of the Native One, an original inhabitant of the Tower predating King Jahad and the Great Warriors. His quest within the Tower drives him to find "something that transcends all things," a concept exceeding desires like wealth, glory, authority, or revenge. Originally appearing in a large reptilian form, Rak was intentionally shrunk by Ranker Yu Han Sung, the Second Floor Test Director, as punishment for mockery. This event granted him a Compression License, enabling voluntary shifts between his smaller, practical size and his original giant state. His compact form resembles an anthropomorphic alligator or crocodile, leading to nicknames like "Alligator" or "Crocodile" from figures like Khun Aguero Agnis. He retains exceptional physical strength and combat prowess regardless of size. Primarily serving as a Spear Bearer, Rak demonstrates capabilities beyond this role, including acute senses for detecting and assessing the power levels of nearby individuals. He possesses an innate power to manipulate stone and rock, linked to his heritage as the Native One's descendant. His combat philosophy revolves around "hunting" – seeking powerful adversaries to consume their strength and grow stronger himself. He consistently challenges formidable opponents, viewing battles as crucial steps toward self-transcendence. Rak exhibits a personality marked by bluntness, confidence, and a primal focus on strength. He expresses disdain for caution or retreat, mocking those who avoid challenges as "baby turtles hiding in their shells." Despite this aggressive exterior, he shows fierce loyalty and protectiveness towards those he acknowledges. He formed an inseparable bond with Twenty-Fifth Bam (whom he calls "Black Turtle") and Khun Aguero Agnis ("Blue Turtle") after teaming up on the Second Floor. This bond deepens significantly; during a pivotal reunion after a six-year separation, Rak expresses profound relief and tearful joy at seeing Bam alive, vowing vengeance against those who harmed him. Rak's commitment to his teammates is prominently displayed during the Workshop Battle arc, where he actively participates in battles to protect allies and further Bam’s objectives. He decisively intervenes to defend Yeon Yihwa from a threat, reverting to his giant form to physically neutralize the adversary. This action highlights his protective instinct towards comrades he still calls "turtles." He openly dismisses the authority of powerful factions like the Ten Great Families, labeling them "lousy turtles" based on his experience with Khun’s family. Rak’s perspective evolves from viewing Bam purely as "prey" to recognizing him as both the "strongest prey and hunter." He uses this hunter-prey dynamic to motivate Bam, urging him to reject the mentality of the "hunted" who hide from challenges. His relationship with Khun develops into one of mutual, albeit abrasive, respect; Rak often chastises Khun for overcomplicating situations or lacking decisiveness. He articulates a simple desire for collective happiness with Bam and Khun, revealing emotional depth beneath his brash persona. Outside combat, Rak displays distinct preferences: a strong fondness for bananas despite struggling to peel them, a lasting grudge against individuals like Quaetro Blitz for burning his bananas, and an enjoyment of consuming large quantities of meat, bananas, and childish foods. These traits add nuance beyond his warrior identity.
