I was thinking (yes I know, I shouldn’t do that, but screw off)
There are some universes where Captain Marvel has minor transmutation abilities. Like changing his outfit and such. But what if he had minor transformation abilities as well.
Like, he can’t shapeshift, but he can change very minor stuff like eye color or, for today’s funny Tumblr post, his voice.
He can’t exactly mimic someone else’s voice without specific spells that he doesn’t bother to learn, but there is one voice that is very easy to mimic with his minor transformation abilities: his own. Or more specifically Billy's.

Captain Marvel is dealing with a simple robber when his phone goes off in his back pocket-dimension. He calls for a time-out, leaving the robbers very confused, before grabbing his phone and gulping.
He vocally coughs a few times before picking up, answering “hi mom” in two octaves higher.
The robbers watch dumbfoundedly as Captain Marvel: champion of magic, hero of Fawcett and high ranking JL member, answers the phone in a seemingly tween boy’s voice having to justify why he is late. Even ending the call with a quick “Yeah, love you too, bye!”
Cap puts the phone back, instantly switching to his normal, lower, voice.
“Sorry guys, gotta go, let’s pack this up quick so I can go home alright?”
