Jim Starlin is already credited at the end of Avengers: Infinity War for his role in creating characters like Thanos, Gamora, and Drax but comments from him during a recent appearance at the Puerto Rico Comic Con point to another of his creations showing up in the still very mysterious Avengers 4.
Apparently, Starlin was given the opportunity to visit the sequel's set and revealed that he'll receive another "Created by" credit when that rolls around next May. He obviously didn't specify which character (or characters) will be showing up so let the guessing games begin because there are lots of options! Given previous comments from the Russos, chances are that it won't be Lady Death, though!
Thanos' father A'lars is one possibility, especially after he was name-dropped by the Red Skull in Avengers: Infinity War. Starlin also created Thanos' brother Eros (a.k.a. Starfox) and his grandfather Kronos, so there are a lot of possibilities when it comes to fleshing out the Mad Titan's family. However, far more exciting are possibilities like Adam Warlock and Pip the Troll but the former seems unlikely.
After all, James Gunn has said that the character will debut in Guardians of the Galaxy Vol. 3 and not an Avengers movie. Who do you think could show up? As always, weigh in with your thoughts below.
