In the final round of a game of Origin Story, each player chooses a card that represents who they have triumphantly become as the result of their journey. This mini-expansion adds 21 new cards to the original deck of 10...and they're not all heroes.
In addition to 7 new superhero cards, we created 14 supervillain cards for the stories that have a more devious ending. They're all in the same deck.
Simply shuffle all superhero and supervillain cards (including superheroes from the original game) into one deck, then deal 3 cards to each player at the beginning of the game. The original game had players receiving 2 cards; you'll instead receive 3 if you're playing with this mini-expansion.
