Charles McNider aka Dr. Mid-Nite is one of the supporting protagonists in Batman: The Brave and the Bold.
He is voiced by Corey Burton.
Dr. McNider was blinded when a grenade was thrown into his room. Undaunted, McNider continued his research with the help of his girlfriend, Myra Mason. After an encounter with an owl, who he later adopted and named "Hooty," he discovered he was able to see in the dark.
McNider developed a special set of goggles that gave him the ability to see at anytime of the day. He also devised Blackout Bombs and debuted in New York as the Mystery Man, Dr. Midnite. He made quick work of the criminal underworld and joined the Justice Society of America.
He and the rest of the Society helped train Batman and Black Canary. Years later, Dr. Midnite reunited with the team and fought an old enemy, Per Degaton. A short time later, he and the Society were attacked and implanted with Starro clones.
