Gwyn Ronny, known as Gwyn Reynolds in English adaptations, serves as the primary antagonist in the Beyblade Burst Rise season (also called Beyblade Burst GT). His background reveals a prodigious focus on mathematics and physics from an early age, demonstrated by activities like dropping balls to calculate bounce distances. Preferring solitude, he spent most of his time isolated in a personal laboratory, detached from social interactions and modern activities such as video games. This isolation contributed to his initial inability to comprehend concepts like friendship or the emotional bonds between bladers and their Beyblades, believing all phenomena could be quantified and predicted through mathematical equations. Physically, he possesses pale skin, fuchsia eyes, and distinctive white hair typically styled in a side braid. His attire consists of a white jumpsuit with a turquoise fur collar, a sea-green jacket draped over his shoulders, a black tie, white boots, and a gold-yellow belt. During intense Beyblade battles or heightened focus, his appearance shifts dramatically: his eyes emit a glow, his braid unravels into long, flowing wavy hair, and his overall demeanor becomes more formidable, reflecting his synchronization with his Beyblade. His Beyblade journey began after witnessing Arthur Peregrine’s battles, sparking an analytical interest. Despite no prior experience, he won his first battle through sheer adaptability and intellectual prowess. He initially approached Dante Koryu with apparent friendliness, assisting in developing Dante’s Command Dragon Ignition. However, after observing Arthur’s destructive capabilities, Gwyn developed a fixation on destroying Dante’s Beyblade, driven by frustration over Dante’s unpredictability, which defied his mathematical predictions. This resentment fueled his antagonistic role, marked by smugness and vanity, such as dismissing Joe Lazure and boasting about his superiority over Dante and Delta Zakuro. Gwyn wielded two primary Beyblades: Royal Genesis Hybrid and its evolved form, Eclipse Genesis Hybrid. These Beys executed specialized moves like Superior-Flux—a synchronization state causing the Bey to glow white with pink and blue sparkles—and techniques such as Royal Eclipse and Eclipse Pulse, generating explosive force or defensive barriers. His battle record remained dominant until consecutive losses to Dante and the duo of Dante and Delta, culminating in a final defeat by Dante alone. These losses catalyzed a pivotal shift, leading him to acknowledge the significance of friendship and the non-quantifiable "Bey Spirit" he once dismissed. His relationship with Dante evolved from manipulative intrigue to genuine respect post-defeat, resolving his earlier resentment. Similarly, his connection to his Beyblade, Genesis, involved a spiritual partnership, though he occasionally disregarded its input in favor of pure calculation. Additional trivia notes include his birthdate on March 14 (Pi Day), blood type AB, zodiac sign Pisces, and age of 10 during Rise/GT events. He shares initials with his Beyblade (G.R. for Gwyn Reynolds and Royal Genesis), a trait shared with three other characters that season. Fan analyses have drawn parallels between his traits—intense special interests, social challenges, synesthesia (experiencing thoughts as colors/shapes)—and Autism Spectrum Disorder, though this remains unofficial interpretation.
