Shounen Power-Up Training Cave

A single-frame anime still from a battle-shounen series, rendered in bold high-energy cel-shading. Interior wide shot of a massive underground cave training chamber: a teenage boy in shredded black training gi stands at the exact center, fists clenched at his sides, as an explosion of violet and white aura energy erupts from his entire body, cracking the cave floor beneath him in radial fractures. The power surge sends stalactites raining from the ceiling. Stone dust billows. Boulders crack. A mentor figure sits cross-legged atop a distant boulder, watching impassively. The scene is lit entirely by the aura glow: violet underlighting on every surface, cave ceiling lost in darkness above. Speed lines converge toward the boy from every edge of the frame. Color palette: deep violet, electric white, obsidian black, slate grey, hot white impact flash. Maximum energy, maximum contrast.
