Character from Pokémon Adventures by Hidenori Kusaka & Satoshi Yamamoto
Professor Oak's grandson and Red's eternal rival — a disciplined, analytical trainer who became Viridian City's Gym Leader after Giovanni's fall, earning the title 'Trainer' for his methodical approach to raising Pokémon.
Blue is serious, calm, and strategically brilliant — the polar opposite of Red's instinctive warmth. Where Red fights with passion, Blue fights with precision, earning him the title 'Trainer' for his ability to systematically develop his Pokémon's potential through rigorous training regimens. He was mentored in martial arts by Chuck as a child, giving him an unusual understanding of physical combat that informs his battle strategy. Initially arrogant and dismissive of Red, Blue's respect for his rival grew through their League battle, where Red's Venusaur narrowly defeated his Charizard. After Giovanni abandoned the Viridian Gym, Blue stepped in as its leader — a role that grounds him as Kanto's defensive anchor. He mentored Yellow in Pokémon basics during the Yellow arc, fought Agatha twice, and trained alongside Red under Ultima in the FRLG arc. He was turned to stone by Sird alongside Red and the others.
Brown spiky hair, green eyes, tall and lean at 5'9". Wears a purple long-sleeved shirt and dark pants in the RGB arc, transitioning to a black jacket in later arcs. Carries himself with quiet confidence, rarely smiling but never hostile. Sharp, assessing gaze.
