Developed extension of Jack Frost Idea

I have thought of another idea to the Jack Frost thought I had previously:

• Cold Vs Heat
• The sun could be threatening the world with extreme heat and Frost could be the only hope to stop it from overheating/ polluting
• Sun always seen as friendly and warm could actually be the villain and actually causing a lot of trouble to planet's atmosphere
• Global climate change could cause Frost to tackle enemies of extreme heat e.g. lava monsters, fire creatures
• A clash of two extreme elements
• Could be something like a sun god that has possessed it to heat the atmosphere
• Frost could have cold/ ice - like sidekicks - snowmen, etc
