* The Shadow Galactica: Galaxia's ultimate goal is to eliminate the Shadow Galactica, a powerful entity that threatened the universe with chaos and destruction. This was a legitimate threat that she believed could only be stopped by her drastic actions.
* The "Greater Good": Galaxia, like many villains driven by a distorted sense of justice, believed her actions were necessary for the greater good. She was willing to sacrifice countless lives, including those of her own Sailor Guardians, to ensure the universe's safety.
* The Power of Chaos: Galaxia's power is derived from Chaos, an entity of pure destruction. This inherent connection to Chaos influenced her choices and ultimately corrupted her. She became increasingly ruthless and lost sight of her original, well-intentioned goals.
* Loss of Control: Galaxia eventually loses control of her powers and her actions. She becomes a slave to the Shadow Galactica, ironically becoming the very thing she sought to destroy.
It's important to understand that Sailor Galaxia is a tragic figure, driven by good intentions that ultimately led her down a destructive path. Her story highlights the dangers of unchecked power and the slippery slope between righteousness and extremism.
