Nightmare Moon's power on the moon is practically legendary—it's her domain, after all! In 'My Little Pony: Friendship is Magic', she literally banished the sun and plunged Equestria into eternal night before her defeat. On the moon, she’s not just strong; she’s the embodiment of lunar energy. Imagine being able to control tides, shadows, and even time perception (since nights feel longer under her rule). The comics even hint she could warp reality there, making her nearly unstoppable.
What fascinates me is how her power contrasts with Princess Luna’s. Luna’s connection to the moon is nurturing, but Nightmare Moon twists it into something oppressive. It’s like the moon amplifies her negativity—loneliness, anger—into raw power. If she hadn’t been sealed there for a thousand years, who knows how much stronger she’d’ve become? That time might’ve even deepened her bond with the moon’s magic.
