Legend
In 4E I made up a warforged vampire...
I called him I-Strahd.
Not exactly gonzo, but a bit off the wall...
Jack Daw - In 4E, you could actually play a talking crow - by RAW.
A pixie druid refluffed as a shape-changing crow spirit from the Feywild, who ended up on the Material Plane after seeing the Raven Queen fly past in her raven form, falling in lust and chasing after her...
Rather than four insectoid wings, he had four single raven feathers as wings. He was loud, raucous, sarcastic and greedy...
And had a nasty habit of snacking on dead enemies.
(The predator druid charger build was actually a pretty passable second-tier striker build with the right items. At-will push and prone effects on their attacks were fun. Pixies have a natural flight speed, and they didn't lose it when they wild-shaped. The Pixie Preda-charger adds some tactically interesting aerial charging shenanigans to the build, and the sight of a large crow whirling around the battlefield knocking ogre-sized opponents down and shredding them was vastly entertaining.)
Polly Pureheart, Pint-sized Paladin of Pelor
Polyphemia Peregrine Pureheart is a halfling paladin. Her personality and visual image is straight-up the stereotypical kid's-cartoon "plucky redheaded kid with freckles and a voice like a chipmunk with a head cold"... She has a childlike personality and a child's simplistic black-and-white sense of right and wrong.
When Polly was a little girl in her halfling village every morning she'd walk outside to start her day, stretch and yawn, and then look up into the sky and say, "Hello, Mr. Sun..."
When Polly was still doing it as a teenager, and still retained her childlike personality, everyone assumed that she'd spent too much time staring into the sun and was more than a little bit touched in the head.
What nobody else in the village realized was that, when Polly was six years old, she'd walked outside, looked up and said, "Hello, Mr. Sun..."
And "Mr. Sun" had replied...
Hello, Polly...
(Although I created her as a joke character, I've also played her in a more serious game as a study of how someone with a clear-cut black-and-white world view deals with living in a much more shades-of-gray world.)
