Kree Karla
With the moonstone playing funny tricks on her, Karla was in conflict with herself over her newly found goodness of heart and this mysterious figure started appearing to her. It turned out it wasn't her in a Kree form, but was someone she, in a sense, could become if she followed her heart. A warrior for truth and justice! From Tbolts 2000 & 41.
Near the end of her conflict with her inner struggle Moonstone's costume began morphing to symbolize what was going on internally. Here is a mix of her Moonstone(tbolt) costume and the shape of her original(Masters of Evil) Moonstone costume. From Tbolts 41
Always so sure of who she was and what she wanted, her stint as a hero started her on a soul journey that led up to a conflict with her inner self, or at least the self she can be if she follows her heart. After confronting the Kree Supreme Intellegence and getting control of here mind and heart again she is just now beginning the redemption journey.Her fate is in her hands, where she will take it, only time will tell.
Here is a nitemare version of the costume, the savageness of the conflict is symbolically shown in the helmet while the Moonstone costume, in this frame, remains relatively unchaged from the original.
Early in her struggle she went to see Reed Richards, she tapped into his datbase for info on the Supreme Intellegence. But typically Karla, she never ASKED first and a battle ensued, she escaped easily, but the great conflict within her had her manifest a new trait, speaking in Kree!
