I already told you: his post-teenage insecurities.

Titus, Batman doesn't win his fights by simply beating the hell out of his opponents. He does it by outsmarting them. In fact, his greatest victories have been accomplished with no violence at all, just a keen intellect and the villainous knowledge of how to use his opponent's emotional weaknesses against them.

Not all battles are fought with fists. Batman fights with his mind, and with that brain he has crippled his enemies in legions.


And red-colored ultrviolet light...and he can't see through lead.
