Cletus Kasady

Spider-Man: Homecoming is the first comic book in which Spider-Man wears his black symbiote suit. So I wouldn't be too surprised if it will happens the same way in the movie. However, I don't expect to see Venom just yet. Instead, I do expect some hints at further installments in the franchise.
One of the villains who hasn't been featured just yet on the big screens is Cletus Kasady, better known as Carnage. And the actor to bring him to life seems to be Michael Mando, from Better Call Saul and Far Cry 3.
Of course, we shouldn't actually believe the tweet (you can see it below). However, why not? Nobody says that Cletus should become Carnage in this installment. Instead he could be just a psychopath and homicidal sadist. Just like in the comics. This would be perfect planning, I believe.

Just have Spider-Man capture this murderer in the beginning of the film and bring him back in the following spider-Man flicks.
Furthermore, if there is one guy who can portray him, that guy better be the actor who brought Vaas Montenegro to life.
