Keith Giffen has died.

If you're a comic book fan from the 1980's and 1990's, you're undoubtedly familiar with his work. He's created and co-created some of the best stories and characters of the day. His humor drove books like Lobo and Ambush Bug and the hilarious Justice League reboot. But my favorit of his works was with The Legion of Super-Heroes. He co-wrote amazing story arcs like The Great Darkness Saga and the highly underrated Five Years Later Saga. The first twelve issues of the latter were some deeply satisfying stories for long-time Legion fans like me...

So many years of entertainment thanks to Mr. Giffen.

Rest in Peace, sir.
