We have one for every single actor even remotely associated to the MCU, I don't see why she should be differentMadame Hydra is my guess.
But until we know who she is playing, is a thread necessary?
“Substantial” suggests that Kim will be more than just a background character and that The Avengers: Age of Ultron may even be setting her up for a bigger role in future Marvel features. Her involvement in the film has been rumored for a while, and according to those rumors she may be playing a doctor with connections to Ultron, who is tasked with Tony Stark’s medical care. There’s not too much to go on right now, but feel free to speculate on Kim’s character in the comments.
My first thought was that she might be playing Madame Hydra. However, Monica Chang is also a possibility, and maybe even Jocasta. I see no reason to doubt that her character will be "substantial" to the plot until I have some evidence that she's not. The fact that they're keeping her character a secret would seem to indicate that she might very well be important.
What is Mantis background with Ultron?
I'm hoping she's Wasp.
I want an Asian Wasp for some reason.
if she were the Wasp, wouldn't be hearing rumors of her being so; in conjuction with the Ant-Man movie (instead of Avengers)? btw, when i google 'Kim Soo Hyun' all i get are pictures of a Korean dude; who looks like he'd be decent as Shang Chi.
Google "Claudia Kim" or "Yoo Ri El"
