Thanos
The Mad Titan's power, whilst formidable, remains fundamentally derivative. His most significant achievements required the Infinity Stones, artefacts he did not create but merely collected through violence and manipulation. Without the Gauntlet, Thanos possesses considerable strength and durability, yet nothing approaching cosmic significance. His power is borrowed, temporary, and ultimately stripped from him by beings of lesser physical stature but greater moral clarity. The universe remembers him not for what he was, but for what he briefly wielded.
The Moon
The Moon exercises its cosmic power through 384,400 kilometres of gravitational reach, generating tidal forces that have shaped Earth's coastlines, influenced evolutionary pathways, and established the very concept of monthly cycles that govern biological rhythms across species. This power requires no gauntlet, no stones, no conquest. It operates continuously, silently, and with absolute mathematical precision that no sentient being has ever matched. The Moon's power is written into the DNA of every creature that responds to circadian rhythms.
