I'm sure many of you probably remember the leak a few weeks back about the storyline in which [Ant-Man](movie:9048) will follow (according to the sources). Well, I've just finished some major comic book research on the theory, and I definitely feel like everything lines up, only too well as usual. The key to the entire storyline isn't even Ant-Man, but rather his daughter, who is an easter egg within herself. Take a look at her origin story via her wikipedia page:
Cassie Lang was introduced to the Marvel Universe as the ill daughter of Scott Lang. Her congenital heart condition forces her father to steal Henry Pym's Ant-Man equipment and Pym Particles, which he uses to rescue Doctor Sondheim, the only doctor able to cure Cassie's condition, from Cross Technological Enterprises.
Suddenly, you have the single dad, Darren Cross and Crossfire who are heavily associated with Cross Tech for obvious reasons, Ant-Man, Scott Lang, and Henry Pym all in one. Darren Cross has a heart condition as well, and has developed technology for it, explaining the need for the suit: to steal the technology.
Possibly the best part about all these connections though is that with Cassie in the films, we might just be able to guarantee an eventual appearance of another female superhero in the Marvel Cinematic Universe: Cassie herself grows up to become Stature, also known as Giant-Girl. Having both the ability to grow very large, and shrink (the same powers as her father's), Cassie is eventually as much of a superhero as her father.
She went on to join the Mighty Avengers and Young Avengers, which are two movies we could end up seeing in the future, as well as the Initiative which appears might be teased in the the upcoming [The Avengers: Age Of Ultron](movie:293035) which features an entire group of trainees at Avengers Tower wearing the same clothing Quicksilver was seen wearing during filming earlier this year.
We don't know exactly how young Cassie will be, but it's likely her superhero stories wouldn't come into play until at least Ant-Man 2, if ever. Still, the idea that her story is an eventual possibility is definitely interesting.
Ant-Man will hit theaters next summer on July 17th, 2015.
