Create a 3D model of an action figure named "Riptide Blaster." He has exaggerated musculature inspired by 80s Masters of the Universe, with a scaly, textured skin. His broad jaw features oversized fangs, and a flowing mane of seaweed-like hair adorns his head. He wears a tattered punk vest with aquatic patches and gauntlets resembling fish fins. His knee-high boots integrate underwater propulsion tech, and he boasts over-the-top articulation.
