If you're gonna come with some dumb ass complaints like that know what you're talking about.
1. The Brood rights are most likely with Fox since they were first a X-Man enemy.
2. Once again, Fox, because WARLOCK IS A fukkING XMAN. Do you even know who these people are?
3. That's Annihilus. I mean, he's mostly humanoid looking so I don't even think that helps your argument. And he's one of the biggest bad guys in the cosmic universe. He had fukking Thanos shook and working for him and was draining goddamn Galactus's power like he was a battery. He rules the entire Negative Zone. If GOTG does well, I think you'd expect to see him as the lead baddie in a sequel or what not. He's not someone they'd just throw in there. Annihilation is probably my favorite cosmic story and its a huge fukking event. They'd have to cover all sorts of shyt and the Negative Zone then introduce Richard Rider and the Kree and Skrulls and thered be so many fukking people running around you wouldn't know wtf is going on. Oh wait you already don't.
4. You're asking me why Beta Ray Bill, a character who is dressed like Thor and on the cover of a Thor comic isn't a major character and introduced in this movie?
Shut theeeeeeeee fukk up
