a 3D model of "Riptide Reactor," a muscular action figure inspired by 80's Masters of the Universe and 90's comic books. He has a hybrid appearance: a grizzled scientist with fish features, scales along his jaw, and a prominent fin crest. His tattered lab coat flows like underwater currents, revealing cybernetic-enhanced arms with exposed wires. His legs resemble armored fish fins, adorned with vibrant colors and neon accents. Hyper-detailed, cartoon style.
