The Kamen Rider Eternal figure stands in a dynamic combat-ready pose, a faithful S.H.Figuarts interpretation from Kamen Rider Double Forever: A to Z/The Gaia Memories of Fate. The sculpt captures a sleek armored bodysuit built from layered panels, with subtle weathering and crisp edge lines that emphasize a mature, battle-worn aesthetic. A tall helmet conceals the face, featuring angular eye slits and a segmented crest that echoes the Gaia Memory motif. The figure includes multiple interchangeable hands, a pair of interchangeable Gaia Memory accessories, and a translucent energy effect part that can attach to the arm or weapon. Finely painted accents highlight metallic trim and emblem details, delivering a display piece that photographs well and holds poses with ease. The presentation scale and joint engineering allow a wide range of action poses, from dynamic lunges to contemplative stances, and the included stand ensures stable display.

Kamen Rider Eternal is introduced in the Gaia Memories of Fate arc as a formidable antagonist who wields the power to manipulate memories and fate through the Gaia Memories. Born from a man driven by a desire to rewrite his own tragic history, Eternal uses the fusion of multiple Gaia Memories to grant him near-omnipresent control over events around him. He seeks to rewrite the world into a version where pain is erased, and order is absolute, regardless of the cost to others. His confrontation with Kamen Rider W and partners drives the narrative, forcing the heroes to confront questions of memory, identity, and free will. Over the course of the story, Eternal’s plans unravel as the protagonists uncover the truth behind the Gaia Memories and the price of meddling with fate.
