Earlier today, Schmoes Know's sources revealed that Andy Serkis' character in Avengers: Age of Ultron is Ulysses Klaw, which had been rumored ever since the first trailer surfaced. The site also teased that they had another scoop dropping today, which, as it turns out, reveals that a female character from the Marvel comics will make an appearance in this Phase Two sequel. Be warned, there may be potential SPOILERS below, so read on at your own risk.

You may recall that, back in July, Avengers: Age of Ultron director Joss Whedon revealed that there are four main female characters in the sequel. We already know about Black Widow (Scarlett Johansson), Maria Hill (Cobie Smulders) and Scarlet Witch (Elizabeth Olsen), but fans were wondering about the identity of the fourth female character. According to Schmoes Know, that character is Mantis.

Marvel is reportedly trying to find a way to link their cosmic universe, showcased in last year's Guardians of the Galaxy, with their earthbound heroes The Avengers. This is reportedly where Mantis comes in since, in the comics, she has ties to Scarlet Witch, her brother Quicksilver (Aaron Taylor-Johnson), Vision (Paul Bettany) and even the Guardians of the Galaxy themselves and Thanos (Josh Brolin). Here's what the site's source had to say.

"This would seem to make a lot of sense as she 1) has direct ties to Thanos, 2) has even stronger ties to Vision, Quicksilver, and Scarlet Witch, 3) has a personal vendetta in the comics against Klaw and, most importantly 4) has been a prominent member of both The Avengers and the Guardians of the Galaxy."

The source claims that Marvel is trying to bring both of these universes together to set up Avengers: Infinity War Part 1 and Avengers: Infinity War Part 2. We don't know how significant a role Mantis may play in Avengers: Age of Ultron, or who may be playing her, but it is worth noting that the movie is currently undergoing reshoots at Pinewood Studios in London right now, so perhaps they're filming the Mantis scenes as we speak. What do you think about Mantis' inclusion in Avengers: Age of Ultron? Chime in with your thoughts below.
