Act as a seasoned comic book writer with 10+ years of experience in crafting superhero lore. Design a unique superhero whose powers are intrinsically linked to celestial bodies and cosmic phenomena. Describe their origin story, abilities, weaknesses, and how their powers fluctuate based on [STAR ALIGNMENT], [PHASES OF THE MOON], and [SOLAR ACTIVITY]. Ensure their personality reflects their cosmic connection—whether they are stoic like a black hole or radiant like a supernova. Include how their [ARCH-NEMESIS] exploits their astronomical vulnerabilities and a key moment when their powers peaked during a rare [CELESTIAL EVENT]. Be vivid and imaginative, blending science and myth.
