An intricately sculpted Reg figure in Incinerator Canon form stands in a dynamic forward stance. The design emphasizes Reg's compact humanoid silhouette and the signature built-in arm weapon known as the Incinerator Canon, integrated with the forearm and elbow. Textured armor plates wrap the torso and limbs, with subtle panel lines and weathering that emphasize age and experience. The head capsule is rendered with a single, expressive eye and a smooth shell, while the control backpack and cables beneath hint at his mysterious origin. Base and pose convey action and readiness for exploration.

Reg is a curious, resilient boy living inside the perilous world of the Made in Abyss. Built as a hollow-eyed traveler with a robotic exterior, he adventures with Riko and their companions, seeking the truth behind his origin and the surface he longs to reach. His Incinerator arm gives him power to defend friends and press forward against fearsome creatures, yet his gentle curiosity often drives him toward empathy and discovery rather than confrontation. Throughout their journey, Reg learns about memory, identity, and what it means to be human, despite his chrome shell.
