During the "Rise of the Demon" storyline, Commissioner Barbara Gordon is kidnapped while investigating Crown Point, a crime-ridden part of Gotham that's protected by a teenager named Nissa who operates as Batgirl. Max gets an alert on Barbara's capture and heads to Crown Point to investigate while leaving Matt to guard the Batcave. Max offers to assist Batgirl and tells the hero she's one of Batman's allies, but Batgirl doesn't trust Batman since he hasn't shown up to combat the multiple criminal activities that occur in Crown Point. Max reveals that she's helped with some of their cases behind the scenes using her technological knowledge. The two team up and take down the dirty cops that captured Barbara (with Max using holograms for illusion-based tactics inspired by Zatanna). Barbara and Max offer their aid to Batgirl whenever she or Crown Point need their help.Batman Beyond (vol. 7) #12
