Wouldn't be Teddy either.
Cap was the one who refused to allow the Kree/Skrulls from abducting Teddy when they showed up trying to claim him.
Cap's handling of Billy and that of Teddy's relationship WITH Billy during the C.C. would also lend a sense of respect and admiration, imo.
Plus he's got a poster of Cap on his wall.
I think out of all the YA, Teddy is Cap's biggest fan.
At this point, I'd say Noh Varr, maybe?
