Some of the best parts of any Marvel movie are the scenes after the credits, and “Guardians of the Galaxy Vol. 2” had no shortage of post-credits sequences. With five clips, there were more end credits scenes than any other Marvel Cinematic Universe film, and some hinted at important things to come. Comic book fans likely picked up on what those scenes hinted at. (Spoiler Alert: Turn around now if you haven't seen “Guardians of the Galaxy Vol. 2” yet.)

While the first scene was Kraglin (Sean Gunn) learning how to use Yondu’s (Michael Rooker) arrow, the second end credits scene was much more ominous. Ayesha (Elizabeth Debicki) reveals that she is working on something called Adam to destroy the Guardians of the Galaxy. She is referring to Adam Warlock.

Director James Gunn told /Film that Adam appeared in an early version of the “Guardians of the Galaxy Vol. 2” script, but there were just too many other new faces. “I think we did something really creative and unique with Adam Warlock. But it was one character too many and I didn’t want to lose Mantis and Mantis was more organically part of the movie anyway. So I decided to save him for later,” he revealed.

While it’s hard to say what Gunn plans, the comics reveal plenty about what fans might expect. Adam Warlock is genetically engineered to be the perfect human. He has super strength, can fly and manipulate energy. He also known for going into a cocoon, which we saw in the clip, and comes out improved every time.

Adam is a pretty complex character who has lived many lives. When he finds out his makers have evil plans for him, he escapes. However, he isn’t exactly a good guy right away. He dies in battle with Thor after he kidnaps Sif to mate with him. He was revived, though, and that’s just the beginning of Adam Warlock’s complicated life.

Eventually, he comes up against Thanos. When the villain finally has the Infinity Gauntlet filled with the Infinity Stones, Adam is the one who comes up with the plan to unite the heroes of the universe. He eventually stops Thanos from using the glove.

It seems like “Guardians of the Galaxy Vol. 3” writer James Gunn might be taking a different route, though. Marvel Studios president Kevin Feige has already confirmed that Warlock will not appear in “Avengers: Infinity War,” so expect some deviations from the comic books.

Adam Warlock’s introduction isn’t the only scene that comic book fans will geek out over. After Yondu’s funeral, Sylvester Stallone’s character Stakar Ogord reunites with a group of old friends. They seem like an older version of the Guardians, and that’s because they are. Stakard, also known as Starhawk, Yondu, Charlie-27 (Ving Rhames), Martinex (Michael Rosenbaum), Aleta Ogord (Michelle Yeoh) and Mainframe (voiced by Miley Cyrus) make up most of the original Guardians of the Galaxy team in the comics.

Will we ever see the adventures they’re headed for? It’s certainly possible. “You will not see them again until ‘Guardians 3’ at the earliest,” Feige told io9. “One of James’ ideas was fleshing out the character of Yondu... and having the fun of tipping our hat to the original Guardians team from the comics. Which is all that is.”

The final post-credits scenes include Groot becoming a teenager, revealing that he probably won’t be a baby in “Vol. 3,” and Stan Lee hanging with the Watchers. The bald aliens are race who want all the information in the universe, and they apparently decide that Stan isn’t telling any worthwhile stories. The Watchers ditch the former Marvel Comics president.

Though some thought Marvel Studios didn’t own the rights to the all-knowing aliens, Gunn recently clarified that Marvel and 20th Century Fox can use them. “There’s a misconception that Fox owns the Watchers, but they don’t. It’s a co-owned property,” Gunn told Coming Soon. That means there is a possibility that fans will see them in a future MCU movie.

“Guardians of the Galaxy Vol. 2” is in theaters now.
