He was Bucky, Captain America’s buddy in last summer’s Captain America: The First Avenger (and voiced the part in Captain America: Super Soldier video game), and now Sebastian Stan has been cast in an upcoming episode of ABC‘s Once Upon a Time. The actual part hasn’t been announced; we only know that his episode will be on at the end of March or beginning of April.

We know he does brave, loyal and mighty very well, but we’ve already seen two princes. Well there could be more of course. There are a variety of fairy tale woodsmen. And then there are the, well, less-nice characters. Any guesses?

Once Upon a Time airs Sundays at 8/7c on ABC.
