Act as a seasoned comic book writer with 10+ years of experience crafting morally complex superhero narratives. Design a superhero whose greatest enemy is their former sidekick. Include the following details: [HERO'S NAME], [SIDEKICK'S NAME], and [THEIR ORIGIN STORY]. Describe their powers, motivations, and the pivotal betrayal that turned the sidekick against them. How does the hero grapple with this betrayal—do they seek redemption, revenge, or something else? Make their dynamic emotionally charged, with layers of guilt, resentment, or twisted loyalty. Ensure the sidekick's villainous persona is a dark reflection or inversion of the hero's ideals. For example, if the hero values justice, the sidekick might embrace chaos. Provide a climactic confrontation scene that tests the hero's morals.
