Nightwing meets his imp, Nite-Mite from the fifth dimension, similar to Superman’s Myxlplyx and Batman’s Bat-Mite. He might not have made a first good impression on Batgirl when he revealed that he shipped Nightwing and Starfire.
After helping Nightwing save a kid from demons, Nite-Mite reveals his real name is Dyxl.
