No because he wasnt
Bane/Thalia made Batman poor, his only weakness
He aint shyt without money
Bane was a fukking lackey ass simp, Joker has NO weaknesses
Well when you have more plot armor than the title character themselves then yea you have no weakness.
So why did Ras hide his identity the whole time against Bruce?
Joker has a neck, isnt that a weakenss
Bane would snapped it in seconds instead of putting up with his bullshyt like everyone else in TDK did
