Weaknesses: Kouka's regeneration is tied to her home planet Kouan and if the Altana in her body is depleted then Kouka can die, she's fine as long as she's on Kouan to absorb more, Altana from other planets are poisonous to her and can slow down her regeneration enough to where she could die, sunlight weakens her
