Uma entrevista com o Yahoo News sugere que os destaques azuis estão relacionados a algum novo gadget da Widow que dispara explosões elétricas. Do artigo:
Scarlett Johansson’s Black Widow suit got the most dramatic alteration. “I went electric,” said Johansson, who reprises the role of Black Widow (her fourth time as the Russian heroine) in reference to the Tron-esque new suit (courtesy of Robert Downey Jr.’s Tony Stark) that allows her to fire electrical blasts of energy at the bad guys.
E da entrevista em si :
Johansson: I had a crazy...like electrical...blast sort of thing...ish. I went electric, I guess.
Design & A Trend ganhou alguns spoilers no set , o que também sugeriu um tema elétrico:
JoBlo has let loose another leak on a Marvel film, this time spilling details on Black Widow's costume for "Avengers: Age of Ultron."
According to the report, the character will feature a "TRON-style" look that will feature electricity flowing through it, which will manifest as electroshock "widow sting" superpowers.
