In case you didn't know, Rainbow girl is a character in DC capable of using all the colors of the emotional spectrum. But according to Geoff Jones, she doesn't understand her powers and use them to their full capability, but instead uses them for fun. Let's assume she did use them to their full capability during this fight against a well know and legendary Green Lantern like John Stewart. And also, she doesn't have the restriction of Power rings. Instead, she has direct access to the Emotional Spectrum. Let the fight begin.
