Professor Zoom
Superman tells Bart and the others that Barry has decided to run back into the Speed Force to protect them. Wally decides to follow Barry and bring him back, and Bart asks him to bring back Max. Shortly after Wally leaves, Linda contacts Jay and Bart to tell them that Professor Zoom, the Reverse-Flash, is at her house attacking Jay and Iris. Bart and Jay rush to the scene, and fight Professor Zoom through the city. During their fight, Professor Zoom criticizes Bart for being a pollutant in the Thawne line due to being a descendant of both an Allen and a Thawne. He bests Bart with ease and is about to stab him with his staff, when Max Mercury suddenly returns from the Speed Force. Bart is shocked and overjoyed by his mentor's return. Wally and Barry return as well and the group of speedsters charge the Reverse-Flash, ready for a fight.
