The boy from Iron Man 3 will be Iron Lad. The actor himself wanted to play that role>>107590611
Highly doubt she will be Ironheart since it's Riri's identity. Why not call her "Iron Maiden", "Iron Lady", "Iron Girl", or "Iron Woman"
You guys pick what name would suit her. Iron Maiden I'm drawn too when we think about how much of an AC/DC fan Tony is
