Yes, he penned the excellent Planet Hulk and its good sibling World War Hulk. I would say Planet Hulk is one of the best Hulk storylines in the history of the character, and certainly the best one in the last ten years. As for a writer you could do a whole lot worse than Pak. Not digging Olivetti's art at all though. I didn't like it in Cable neither in Punisher War Journal.
