Official Disney Bio

 * "Hans is a handsome royal from a neighboring kingdom who comes to Arendelle for Elsa’s coronation. With 12 older brothers, Hans grew up feeling practically invisible—and Anna can relate. Hans is smart, observant and chivalrous. Unlike Elsa, Hans promises he’ll never shut Anna out; he just might be the connection she’s been waiting for all these years."
