- (Paradox to Athena and the Saints) "It isn't love that wins battles...It's hate!"
- (Integra to Paradox) "You long for an impossible future! I swear on my name, as the Gold Saint of Gemini, that I will protect them! The people of Earth and the goddess Athena!"
- (Gallia to Hyperion) "What fun would that be? Let the maggots fight each other, and watch the bloody battle from a distance. What could be more amusing?"
- (Harbinger to Paradox) "I never knew my parents or brothers. But I can't stand by and watch as sisters kill each other!"

- (Paradox to Integra) "Why do you hesitate? You hate me, right?! Hurry up and finish me already! Don't make me embarrass myself further!"
