Tatsuyuki Tokoname operates professionally under the hero name Slidin' Go, projecting a publicly affable and energetic personality. He possesses a physically imposing stature, standing 187 cm tall with a muscular build, small black eyes, a circular nose, and a prominently large, square jaw that positions his mouth notably high on his face. His hero costume is a purple, skin-tight bodysuit adorned with black arrow-like markings across the chest, waist, and thighs, paired with knee-high boots featuring arrow-shaped cavities. The ensemble includes a black mask covering his head and eyes, elbow-length green gloves displaying golden scale patterns, a short green scarf-like cape secured by a golden disc, and a thick black belt with a large buckle. Publicly, Tokoname maintains a chipper and encouraging demeanor, frequently offering praise and assistance. He notably commended Katsuki Bakugo and Shoto Todoroki following their early hero work, hugging them and predicting their future success as top heroes while volunteering to clean up the resulting debris. This friendly facade, however, concealed his absolute allegiance to the Meta Liberation Army, later known as the Paranormal Liberation Front. The MLA strictly adhered to Destro's ideology, advocating for unrestricted meta ability usage as a fundamental right, and Tokoname enforced strict hierarchical etiquette among its members. His double life involved covert operations for the MLA. Shortly after his public interaction with Bakugo and Todoroki, he escorted the League of Villains into Deika City, ostensibly guiding them to the MLA commander. During this escort, he performed the MLA's signature hand salute, revealing his true affiliation. He participated in securing the city during the MLA's activities to prevent outsider access. After the MLA merged with the League of Villains, he joined the newly formed Paranormal Liberation Front. Within the PLF's Vanguard Action Intelligence Regiment: Carmine, he served as the second-ranked adviser under Skeptic. Tokoname demonstrated strict adherence to rank within the PLF, chastising Keigo Takami (Hawks) for not notifying superiors of his movements and asserting his higher status. Skeptic promptly corrected this assertion, clarifying Tokoname's actual position and emphasizing Hawks' superior access to information. Tokoname's role primarily involved surveillance and operational support rather than direct combat. His Quirk, an unnamed sliding ability, grants him frictionless movement across surfaces, significantly enhancing his speed and mobility. He typically activates it with his legs together and hands on his hips. This power proves more effective for patrol and rapid transit than offensive purposes. Tokoname's covert activities concluded during a large-scale hero operation targeting the PLF. While on patrol, he noticed the absence of other pro heroes, leading to his apprehension by Death Arms. His arrest alongside other PLF members exposed his affiliation with the Front, shattering his usual calm demeanor with genuine shock and marking the end of his dual identity. Additional details include his birthday on March 1, making him 36 years old during the main story events. His favorite activity is reading. The series creator, Kohei Horikoshi, expressed enjoyment in designing the character. Tokoname shares his birthday with the hero Mirko. His Quirk bears a superficial resemblance to The Crawler's from the "Vigilantes" spin-off, though Tokoname can slide while standing upright. His character design incorporates inspirations from classic space ranger aesthetics.
