Jonathan Lethem gave the commencement address at my brother's graduation. Jonathan Lethem is going to be writing Omega the Unknown. From Lethem's essay The Five Most Depressed Superheroes:

5. Omega The Unknown. Like Black Bolt, he never spoke. Energy beams came out of his hands, not always at his command. He might be considered Superman's depressed cousin, since he'd come from a destroyed planet. Unlike Superboy, Supergirl, or Superdog, Superman has never acknowledged Omega. Omega's priorities were very unclear, and so he had the power to depress others, as well as himself. Omega's comic book was so punishingly dull that Marvel began to put The Hulk and Spiderman on the cover, and once, in a measure of striking desperation, Scrooge McDuck made a guest appearance. After ten issues the title was cancelled anyway. After cancellation, Marvel was contacted by attorneys from Omega's home planet, which turned out not to be destroyed at all. This resulted in the first recall of the entire run of a published comic book in the industry's history. Until a successful appeal of the court's order in 1996, Marvel was still required to refund the full cover price of any issue of Omega The Unknown returned by a consumer, as well as the cost of return postage.
