Our latest set of Marvel rumors include, Chameleon in Spider-Man: Brand New Day, Sadie Sink’s character being a false flag and potentially leaked X-Men them from Doomsday. Let’s begin with some Barside Buzz from Daniel RPK, who has a good hit rate for Marvel.
First off, Daniel says on his Patreon that he thinks Chameleon may be in Brand New Day. The character was last used in Sony’s ill-advised Kraven the Hunter. However, given that movie killed the SSMU, there’s no reason the character can’t be used we know of. There were shapeshifting rumors, and this has everyone thinking Sadie Sink is playing Shathra, but Daniel is not so sure. Even Daniel seems a little sceptical about this one folks, but it is what he heard.
This takes us to Daniel’s claim (see below) that he thinks the Sadie Sink as Shathra rumors may have been a false flag to keep her real identity secret. We can say with some certainty, given the leaked trailer, that Sink’s role is antagonistic. However, there’s little else we can say for definite thus far.
And a lot of misdirection from the set didn't help.

Then Daniel got some backlash from fans and posted this response to his own post.
“I see people accusing me of “backtracking” on her not being Shathra, but I never actually said she was her. I heard the rumor but I never posted about it myself publicly. I only explained why I think others believed that’s who she was playing.
Also for those asking how I could hear details about the character without knowing for sure who she’s playing: it’s simple, the details I’ve heard could describe multiple Marvel characters. So until I have her actual name I can’t be certain.”
As per my article yesterday, linked above, I also have my doubts this is Shathra. Yet, I have nothing to base that on, other than it feels off to me and always has.
Lastly, this social media account is claiming they have the leaked X-Men theme from Avengers: Doomsday. There’s a hint of the X-Men 97′ theme there. However, it’s suspiciously not been taken down now for almost 24 hours. In other words if it’s legit, why has Disney not copyright pulled it?
It could just be they don’t care too much about a piece of the soundtrack getting out. See what you think?
