Overcoming fear immunity

[KnotAguru]

Are there any class abilities/feats/spells/items to overcome a target's fear immunity (such as a paladin)?

There's the Anti-paladin's Aura of Cowardice.

Stick him in an Anti-Magic Field?

You might have trouble applying fear effects, though.

Anything other than an antipaladin? I thought I saw a feat somewhere that let you override fear immunity? Maybe it was in 3.5? Or maybe I'm losing my mind...
