MCU Phase 4: Every Single Character Confirmed (So Far)

44. Melina (Rachel Weisz) - Black Widow

Set to be played by Rachel Weisz, Melina will apparently be an antagonist opposite Natasha, but Weisz has confirmed since the film's announcement that she and Nat have a complex relationship. In her own words, she's also a Red Room graduate, which makes her particularly dangerous, though the nature of her training is even more intriguing than Natasha's:

"[Melina has] been cycled through the Red Room through the Black Widow Training Program, five times since I was a child. So, I'm pretty seasoned spy."

Does that mean she's resistant to the training? Or that she's gone rogue? Could she be the one who turned Natasha? Or are we looking at misdirection ahead of the inevitable reveal that she is actually Taskmaster?
