A vocal processor?
Call it now, she's Doomfist and runs around in a giant mech suit. And using the vocal processor makes herself sound like Terry Crews.
That way we get the best of both worlds. A super smart young black girl as one heroes, and Terry Crews as Doomfist like everyone has been begging for. It's a win/win.

She creates a robot posing a Doomfist but with some of Lucio's likenesses. the colors and the Branford arm lead me to believe this.
