A character who is so popular and impactful that many other characters created afterwards are heavily inspired by it. They share even more than its Character Archetypes, they are its Expies: basically the same old character recycled, with some minor changes, to make it fit into the new setting. The original one gives inspiration not just for their basic Characterization Tropes, but for parts of their relationship dynamics, personality, and appearance. A Super-Trope to Overused Copycat Character (when a work jokes about how many times a certain character has been copied).
