From the publisher's website:

The Space-Time Calliope is vast and dangerous, waiting for courageous heroes to save the day. You’re those heroes! Become the Bravest Warriors and battle your way through a myraid of encounters to Victory! Encounters is a new dice and card game mechanic from Catalyst Game Labs where players try beating the cards individually, but with a good dollop of player interaction. In the Encounters: Bravest Warriors RED DECK you play this fast and fun game as the characters from the show: DANNY, BETH, JELLY KID or CATBUG; in the BLUE DECK you play as CHRIS, WALLOW, PLUM or IMPOSSIBEAR! Both decks are for 1 to 4 players, playing a game in 15-30 minutes. Enjoy many new Encounter and Item cards to challenge your fun from one deck to the next, or combine them both for up to 8 player action!
