I don't think Stan's relationship with Kenny was contentious.I've never heard them speak harshly of each other.But Stan's role as consultant held no real power.(That's why the name change from Bruce to David stuck)Kenny ran the show (literally!smiley: tongue) I think the reason Kenny backed down over wanting the Hulk red was more for marketing reasons.I'm sure Marvel put their collective foot down,not wanting the Hulk to look wildly different from his comic book depiction.
