Kapow!

Description from the publisher: Superhero — or supervillain? You decide in this buildable dice game. Use your dice to attack, defend, or increase your power for the next round! In Kapow!, players go head-to-head in a classic silver-age clash of good vs. evil. (Think 1960s Batman and Green Hornet!) Players choose to be a villain or hero (which determines your starting trait dice) and all players start with a blank buildable "action" die. Each round players roll their dice. Behind a player screen, the dice are allocated to attack, defense, or power up. When players power up, they can get anything from new faces for their action dice to new blank dice. The fun is fast and furious — get ready to rumble superhero style with Kapow!
