"Avengers: Age of Ultron" is already stuffed with more Marvel characters than every other Marvel Cinematic Universe movie combined (well, excluding The Avengers, for obvious reasons). You've got every major Avenger, plus most of his or her supporting casts. You've got newcomers like Scarlet Witch (Elizabeth Olsen), Quicksilver (Aaron Taylor-Johnson) and the Vision (Paul Bettany). And there's Ultron, obviously, even if James Spader's robot villain isn't likely to hang around for more than one movie.

But the latest Avengers movie might be covertly trying to launch another major Marvel character- Amadeus Cho. For those who don't know, Amadeus Cho is the seventh-smartest man in the world, and a regular player in comics alongside the Incredible Hulk, and sometimes Hercules. According to ComicBook.com, Claudia Kim will be playing a character named Helen Cho in the film (a doctor, no less), who may end up being Amadeus Cho's mother.

The official description for Helen Cho sounds like this:

"Dr. Helen Cho (Claudia Kim) is a world-renowned geneticist and an ally of The Avengers. From her offices in Seoul, South Korea, to sharing workspace with Bruce Banner in his lab at Avengers Tower, Dr. Cho's research and technology help keep The Avengers in the fight."

As well, MoviePilot officially confirms that Helen Cho is going to be Amadeus Cho's mother. So the question remains - just what is Amadeus Cho going to be doing in the Marvel Cinematic Universe? There's a few options, but perhaps the most likely is another TV show, like "Agents of SHIELD." The star of that series, Agent Coulson, was transplanted into Agents of SHIELD after his death in The Avengers, so it would make sense that the second Avengers film would create the second Marvel series. As well, it's been confirmed that Marvel's developing an Agents of SHIELD spin-off. This could very well be it.

"Avengers: Age of Ultron" will premiere in theaters on May 1, 2015.
