Bane is highly intelligent; in
Bane of the Demon,
Ra's al Ghul says that Bane "has a mind equal to the greatest he has known."
[8] In prison, he taught himself various scientific disciplines equal to the level of understanding of leading experts in those fields.
[4] He knows six active languages and at least two additional arcane and
dead ones. Among these are Spanish, English,
Urdu, Argh,
Persian, and
Latin.
[8][41] The
Bane of the Demon storyline reveals that he has a
photographic memory. Within one year, he is able to deduce Batman's
secret identity.
