The Moon
The Moon's gravitational influence shapes life on Earth in ways most organisms never consciously recognise. It generates tidal forces that move billions of tonnes of seawater twice daily, creating ecosystems in intertidal zones. The lunar cycle affects circadian rhythms in countless species, from the spawning of coral to human menstrual cycles. Its gravitational stabilisation of Earth's axial tilt may have been essential for the development of complex life. Without the Moon, our planet would wobble chaotically, making seasons unpredictable and evolution considerably more challenging.
Wolverine
Wolverine's influence, while geographically limited, operates with remarkable intensity. He has shaped the outcomes of multiple global conflicts, prevented numerous apocalyptic scenarios, and mentored generations of young mutants. His presence in the X-Men has altered the course of human-mutant relations repeatedly. However, his influence remains largely confined to Earth, specifically to situations involving people who need stabbing or gruff life advice. Beyond our atmosphere, his cultural impact diminishes rapidly.
