Are there any stories covering a period of time when Bruce Wayne fought crime as a masked vigilante, before dressing as the Batman?
Looking for a comic or something in the DCAU preferably.
In Mask of the Phantasm he originally goes out just wearing a ski mask. He comes back and tells Alfred he failed because they didn't fear him. Then he starts to look for a way to inspire fear in criminals and comes up with the Batman suit.
Mask of the Phantasm is kind of like Batman Year One for the DCAU.
In the early 50's, when Bruce was a child, he learnt detective work from Harvey Harris, in order to do so he created a costume which looked like Robin's.
If I remember correctly it is in the Untold Legends of the Batman
