Guardians of The Galaxy 2 Rumours:

• The guardians will have more new members including Adam Warlock (is a rumour) and more famale members. Other possibles are Moondragon, Cosmo, Mantis, Bug, Jack Flag, Vance Astro, Quasar or Protector. Miss Marvel and Nova would not appeared because James Gunn (the director) hates that kind of characters
• Thanos could appear only if brings something important to the story
• the "Awesome Mix 2" will be heard

• Drax will have more story in this film
• the father of Peter Quill will be revelated.
• There will be more Infinity Gems maybe the soul one (if Adam warlock appears) or time one (for Gamora)
• There will be more Gamora's story and her relationship with thanos and Nebula and maybe more love with Star lord
• There will be more Yondu backstory and its relationship with the family of Quill.
• Hulk could come and join the guardians and be a kind of free adaptation of "Planet Hulk" and this can lead us to the character Beeret, the red girl, who was on Star Lord's Ship at the beginning.
•There will show more races and planets.
• A cameo or appearance of some avenger (mostly tony stark)
• They may show the process by which revives Groot
• Maybe "War of Kings" and "Planet Hulk" will be the main basis for the story of the film. And maybe the title will be "Guardians of the Galaxy: War of Kings" and that is amazing!
