Key Issue Comics:
Detective Comics 400, 1st Appearance of Man-Bat
Why Detective Comics 400 is a Key Issue Comic
400 issues in – that’s quite a milestone for Detective Comics, which was started way back in 1937.
For this monumental issue, Batman gets a new foe – Man-Bat!
Dr. Kirk Langstrom was a scientist who developed a serum that could give humans bat senses.
Hoping to cure his progressive deafness, Dr. Langstrom tests it on himself, but is turned into a ravaging Man-Bat.
Later, Batman and Man-Bat team up to fight off the Blackout Gang (first appearance), but their partnership is short-lived and Man-Bat mysteriously disappears.
He shows up later in DC #402 where he and Batman face off as enemies.
The cover of Detective Comics #400 is unique in that it features Batman, Robin, and Batgirl, where previous issues left out Batgirl.

Man-Bat may not be as memorable as The Joker or Bane, but he has become a lasting DC villain who still makes appearances today.
