On the Eurobricks message board, a list has been shared revealing the 20 minifigures that will make up The LEGO Batman Movie Collectible Minifigures Series 2. The new wave of minifigures is expected to be released in January 2018.
Friends and Family Harley
Friends and Family Alfred
Swimming Pool Batman (with dolphin)
Soccer Mom Batgirl
Many of the minifigures on this list fill in gaps left by the original The LEGO Batman Movie sets and series of minifigures. Friends and Family Harley and Alfred will complement the minifigures in the upcoming 70922 The Joker Manor set.
