The Marvel Cinematic Universe (MCU) is one of the most successful franchises in film history, and while the films have made comic book stalwarts like Iron Man and Star-Lord household names, not every character in the MCU has gotten the spotlight they deserve. Some haven’t even been named yet!

The following are obscure characters that have either appeared in a Marvel movie or TV show, been referenced as existing, or can be deduced to exist by what has been shown on screen. Therefore, it's technically correct to state that all of these characters exist in the same universe as Captain America and Dr. Strange. And, as every geek knows, technically correct is the best kind of correct.  

How many of these characters did you know where part of the MCU? Or, frankly, how many did you know existed in the first place?

    Long-time Iron Man villain and life-long loser, Donnie Gil has impressive powers as the Blizzard, but he doesn’t have the guts or ambition to do much with them. He did try the hero racket for a while as a member of the Thunderbolts, but it didn’t last.

    He appeared in the MCU as a hapless college student, accidentally granted powers in the Agents of SHIELD Season 1 episode “Seeds.” He returned as a Hydra tool in the second season episode “Making Friends and Influencing People,” making him a regular threat for the good guys. He still hasn’t worn a costume yet.

  • Celestials

    Unfathomable space gods from the mind of artist Jack Kirby, the Celestials were influential in creating life, intelligence, and superpowers throughout the Marvel Universe. Little is known about this race of giants except what their creations believe about them, and the fact that other cosmic beings fear and respect them.

    While the Fox movie, Fantastic Four: Rise of the Silver Surfer, was afraid to show the giant Galactus, the MCU’s Guardians of the Galaxy film depicted a dead Celestial’s head as Knowhere, the space station where the Collector kept his collection. They also mention a living Celestial called Eson the Searcher, establishing him (it?) as a previous possessor of the Infinity Stone of Power.

  • Amadeus Cho

    Teenager Amadeus Cho is the eighth (or ninth) smartest human on Earth, and his intelligence has led him to be a substitute Ant-Man, substitute Hercules, and most recently, the Totally Awesome Hulk. Cho has become more-and-more popular since he first appeared in 2006’s Amazing Fantasy #15, so you’d think he’d be a major part of the MCU, right? Wrong.

    According to the credits and novelization, the dweeby computer guy who mooched a pizza off Bruce Banner in The Incredible Hulk was Amadeus Cho. Admittedly, this was only the second film in the MCU, and if Marvel realized how long they’d keep the franchise going, they probably would have saved him for later. Avengers: The Age of Ultron featured scientist Helen Cho, named for Amadeus’s mother in comics, so maybe we’ll get another version of Amadeus later on.

    The Elder Demon Chthon is one of the most ancient and powerful evil forces in the Marvel Universe. He existed before most other gods, and created the first magic in the world. Chthon created the indestructible Darkhold book to tempt humans, and anyone who reads from it can be blessed and cursed in frightening ways.

    Despite being previously grounded in science, the MCU has introduced more mystical elements since welcoming Doctor Strange into the fold. In the fourth season Agents of SHIELD episode “Meet the New Boss,” they officially introduced Chthon’s Book of Sins, the Darkhold, to the live-action universe.
