Rawk, sorry, but I do agree with what people are saying. However much effort was put into the previous one doesn't really matter because the original was preferable to this new one, which is a bit generic comparatively. I would prefer that you stick with the original version, but I could approve this one if you really, really want it and if you write out the weaknesses. Kalama, for example, was never weak to cold or ice despite being designed entirely around fire, not even when he started out with total immunity to all things related to fire and heat. Ice and cold affected him just like any normal character would be affected.
So while I would really prefer you stick with the original, cooler version, if you're dead set on using this new version at least write out the elemental weaknesses.
