I ended up finishing this. However I didn't like how so saturated it was with the blue so I toned it down a bit. I like the warm look it gives off now. Blue fire Carolyne is a lot stronger and regular Firegirl Carolyne. Blue fire Caroline is called Ultimate Firegirl. It is a form which turns Carolyn'es fire blue, meaning her power is stronger and her flames are hotter. This is known as Ultimate Fire. When Carolyne's Firegirl form reaches blue fire, she becomes Ultimate Firegirl. Think of it as an upgrade.
