If you use Android Pay today, you’re in for a surprise. Like our beloved animations of space explorers, Halloween haunts, and Wimbledon players in the past, five of our Android bots have channeled their superpowers to become Justice League Super Heroes in celebration of the movie. Starting in the next few days through December 31, you can see them sprint, soar, and fight to defend the planet when you pay with your phone.

How did these heroic characters make their way into the app? It began back in 2016, when the Android Pay team designed an animation–an Android bot dressed up as a space explorer–to surprise our fans. This little space traveler sparked so much delight that the team created more, drawing inspiration from Diwali, Halloween and Chinese New Year, among other celebrations.
