Batgirl Jumping Spider

A little scene showing Batgirl (Cassandra Cain) pulling off something from Ninja Warrior: The Jumping Spider, an obstacle that has knocked off lots of competitors at Mt. Madoriyama. She's, at the moment, investigating a factory that may be developing weapons against the Justice League (note the doors with the logos of Superman, Wonder Woman, Flash, Green Lantern and Aquaman).
