Fan Casting Dr. Leslie Thompkins in The Dark Knight: Legend of The Batman

Leslie Thompkins was a close friend of Dr. Thomas Wayne and his wife Martha. She took it upon herself to look after their orphaned son, Bruce, after the two of them were killed. Leslie often acted alongside Alfred Pennyworth, as a parental figure and guardian for young Bruce. As an adult, Bruce is still very close to Leslie, viewing her as somewhat of a surrogate mother. Although Leslie doesn't agree, she still supports Bruce in his crusade against crime and regularly patches up his wounds.
