The Joker as written by (or acted by) whom? He's a lot less mutable than his arch-nemesis Whats-His-Name, but there have still been a lot of incarnations. Even his background has been changed several times (personally, I like it best when DC says, "Background: Totally unknown," because it seems to me to fit him best.) Are you creating him at CR 14 for a reason, or should we be suggesting more appropriate CRs?

(About the only thing I feel we can feel sure of is that he's made the Dirty Trick feat tree a priority!)

Bard level 3 for class abilty for

Satire (Su): A court bard can use performance to undermine the confidence of enemies who hear it, causing them to take a –1 penalty on attack and damage rolls (minimum 1) and a –1 penalty on saves against fear and charm effects as long as the bard continues performing. This penalty increases by –1 at 5th level and every six levels thereafter. Satire is a language-dependent, mind-affecting ability that uses audible components. This performance replaces inspire courage.

Mockery (Su): A court bard of 3rd level or higher can subtly ridicule and defame a specific individual. The bard selects one target who can hear his performance. That individual takes a –2 penalty on Charisma checks and Charisma-related skill checks as long as the bard continues performing. This penalty increases by –1 every four levels after 3rd. Mockery is a language-dependent, mind-affecting ability that relies on audible components. This performance replaces inspire competence.

and

Alchmist level 12 for

Madness bomb: The alchemist's bombs do more than sear flesh—they sear the mind. A creature that takes a direct hit from a madness bomb takes damage from the bomb plus 1d4 points of Wisdom damage. Reduce the amount of normal damage dealt by the bomb by 2d6 (so a bomb that would normally deal 6d6+4 points of damage deals 4d6+4 points of damage instead). The amount of Wisdom damage dealt by a madness bomb is reduced by 1 for each madness bomb that hit the target in the past 24 hours, to a minimum of 1 point of Wisdom damage. An alchemist must be at least 12th level before selecting this discovery.

Confusion Bomb* (Su): The alchemist's bombs twist the target's perception of friend and foe. A creature that takes a direct hit from a confusion bomb takes damage from the bomb and is under the effect of a confusion spell for 1 round per caster level of the alchemist. Reduce the amount of normal damage dealt by the bomb by 2d6 (so a bomb that would normally deal 6d6+4 points of damage deals 4d6+4 points of damage instead). An alchemist must be at least 8th level before selecting this discovery.

As what Joker in time written or played by? None real but just a mash up of all.
