Greg Pak says at least a couple times in interview, that Cho has "a Dark Hulk". AFAIK the first time "Dark Hulk" ref was in TIH 370/371 when an inter-dimensional being takes over the gray Hulk. Would think Pak knows this history, so maybe doesnt mean anything other than same name. Or maybe it could be a clue to something more.
Dark Hulk being a fully separate personality type than Cho-Hulk is a welcomed change to me. If this duality is shown more than the tool-ish Cho-Hulk, I'll be thrilled. My thinking is this'll prolly be Pak's last chance to see if there's an audience (for him and Cho) with the return to Planet Hulk story and becoming The Incredible Hulk title and numbering. Dep on sales, Banner/Hulk comes back with a milestone number; 725, 750 775 etc and prolly high profile new creative team. Pak would have been given ample chances to turn the series around. And if this potential failure ALSO doesnt result in 12+ yr editor Mark Paniccia's departure too, then we and Hulk are f***ed!!
I hope Axel Alonzo departs as well but we won't be so lucky. They already teased the Chulk in the trunk and nothing ever happened so I can't say I have much faith in Chulk to improve. I am also not excited about the artist for this Planet Hulk return coming up.
