Avengers: Infinity War is already shaping up to be the most jam-packed superhero epic that we’ve ever seen. Remember when we were all impressed to see Nick Fury bring six heroes together in The Avengers? Infinity War has all of them, plus the newer Avengers, plus the Guardians of the Galaxy, also Spider-Man, and Doctor Strange. (Phew!) But is there room for one more mystery Avenger? Today’s Nerdist News is on the case with intergalactic implications!

Join host and the only heroine with cosmic awareness, Jessica Chobot, as she looks at some recent comments made by Stan Lee, the co-creator of many of Marvel’s top heroes and the star of countless cameo appearances. The famously verbose Lee may have gone a little too far in a new interview when he said that an Avenger will debut in Infinity War who hasn’t previously appeared in the MCU.

It’s gotta be Captain Marvel, right? Brie Larson’s heroine is all set to make her solo debut in 2019, and it’s already been rumored that she’ll be in Infinity War. But given the way that Lee’s assistant had to step in to keep him from spilling the beans, we’re thinking that this is a genuine secret that Marvel has been able to keep under wraps. Until now.

Could it be Namor the Submariner? Marvel has reportedly reclaimed the Namor rights from Universal Pictures, and he is one of the very first Marvel superheroes and a member of the Avengers in the comics. Namor is also a mutant, but that could probably be ignored or retconned.

Another strong possibility is the Red Hulk. Captain America: Civil War went through the trouble of reintroducing William Hurt’s Thunderbolt Ross. The next logical step is to see Bruce Banner’s personal nemesis acquire Hulk powers of his own.

Another character we’d love to see is She-Hulk. Jennifer Walters is Bruce Banner’s cousin in the comics, and she gained a measure of his power through an emergency blood transfusion. While we would have probably noticed another big name actress joining the cast as the fun loving She-Hulk, Marvel did manage to surprise us with those characters in the end credits of Guardians of the Galaxy Vol. 2. So perhaps we’ll see an even bigger surprise next year during Infinity War.

Who do you think should be the mystery Avenger? Assemble in the comment section and let’s discuss!
