Character(s) Spotlight: Coldmoon and Dragonfire

In November 2011, Marvel released Point One #1, a comic that touted "The Future Begins Here!" It set up stories across the Marvel Universe, including major ones like Original Sin, Avengers VS X-Men, and Age of Ultron, but right there in the middle was the first appearance of two brand new characters: Coldmoon and Dragonfire, two yin yang-themed Chinese teenagers with fire and ice powers.

These characters were never seen again. According to Fred Van Lente in his Reddit AMA, they were created for the Marvel Heroes video game, by Gazillion Entertainment, to help the game appeal to the Chinese market and included in Point One to help promote that. Normally this is where I'd show you the video game versions of them as proof, but they never appeared in the game. This issue is literally the only time Coldmoon and Dragonfire appeared anywhere.

It's a shame; with such a high profile introduction, you'd think someone would've seized the opportunity to use them somewhere. Oh well. For all we know, someone will dust them off twenty years from now and they'll be the surprise character find of 2040. Worked for Squirrel Girl!
