Guardians Of The Galaxy Vol 2: 20 New Details Just Revealed
4. There Is A Link To Hulk
Okay, so it's a little tenuous, but there is a link to the Hulk in Guardians Of The Galaxy Vol 2.
When Star-Lord, Drax and Gamora seek out Ego and Mantis, they find them on the planet Berhert, an Earth-like lush planet (it's even third from the sun), which has appeared in one notable Hulk story in the past.
That was the sight of a battle between Hulk, Warlord Supreme and the Galaxy Master that allowed him to help free the Sagittarian people and their leader Princess Daydra. None of this will come into play in the film at all, but it's a nice link.
Kevin Feige confirmed that there's another Easter Egg planet in there too when he revealed how many different planets would be on show (as well as Earth where a little bit is set):
“Sovereign’s a planet, Berhart’s a planet, Contraxia’s a planet, J’son’s a planet, so four/five. We see glimpses of two or three other worlds, but these are the major locations.”
J'Son of Spartax is the in-comics father of Star-Lord, and it's odd that his name is being used as a planet, but again a nice link. Meanwhile, Contraxia is the home planet of the mother of Jack Of Hearts.
