1. this is cap's movie
2. the falcon is basically batman's black robin
3. cap got a black sidekick... more like a partner since he was older than your avg sidekick, but for a while it was cap and falcon
in the ultimate universe the falcon is a smart scientist, not reed richards smart, but pretty up there, i think he talks to computers instead of birds. i included ultimate falcon, cuz we all know how the MCU (marvel cinema universe) loves to take it's character cues from the ultimate universe.
they'll probably use his origin story from ultimate universe, since in 616, he lost both his parents became a thug, pimp, beat ppl up, talked to birds n shit, in fact it sounds like the blueprint for mike tyson/(insert rapper name), then he met cap on an island somewhere and they became bff's fighting crime and he became a social worker. (i think they retconn'd him but who cares)
