13 years ago - Ulthoon is spawned in the Mutogenic Mists of Deep Rann. He battles Adam Strange and is cast into deep space.
11 years ago - Ulthoon is recovered by professor T.O. Morrow, and used as basis for his new android.
10 years ago - With his android body completed, Red Tornado is send to infiltrate the Justice League, but chooses to abandon his creator and join them.
9 years ago - Red Tornado sacrifices himself to save the Justice League, his consciousness uploading itself into the League Database.
Red Tornado is a fine, simple character, but he really doesn't hold up on aggressive inspection. His attempts to have a human relationship or a human identity all sit weirdly on the stomach, and the ideas about him being somehow immortal that were introduced by Brad Meltzer in his weirdly uncomfortable run on the Justice League all twist and complicate a character that simply doesn't need to be complicated. We made a specific decision to have him sacrifice himself at the end of the satellite era of the Justice League. It's the era when the character flourishes, and from there it felt more natural to have his consciousness be the artificial intelligence behind the League's technology.
We deliberately avoided some of the post-crisis ideas about his origins that re-imagined the character as an air elemental in favor of his cool Raanian origins. A sentient tornado from an alien planet being housed inside an indestructible android is the sort of story you just don't get outside of comics.
