Rockman DASH - Aku Rock is rendered in the compact, highly poseable 4 Inch-Nel scale by Sentinel. Standing roughly 100 mm tall, the figure captures the character's signature silhouette with a bulky armored chest, angular helmet and sharp lines that evoke the game’s retro-futuristic aesthetic. The paint scheme combines deep blues with metallic silvers and bright accent colors to highlight the energy core and weapon details. The figure features multiple points of articulation at the neck, shoulders, elbows, wrists, hips, knees, and ankles, allowing dynamic display options from ready-for-action stances to a crouched scout pose. A subtle gloss finish enhances the sculpt’s crisp edges and panel lines, while clean panel delineations emphasize the character's mechanical design.

Aku Rock is introduced in Rockman DASH as a formidable rogue warrior who twists data streams into weapons and corrupts energy cores. Born from a failed experiment within Neo Arc's orbital labs, Aku Rock embodies a corrupted ideal of the hero's world, challenging Rockman Dash at every turn. This backstory frames him as a cunning tactician who uses terrain manipulation, energy blades, and sudden ambushes to outmaneuver opponents. The figure's design mirrors this narrative: angular armor, jagged edges, and a restrained color scheme that hints at both high-tech prowess and rogue allegiance. Collectors display him as the unsettling centerpiece of any Rockman collection.
