Because I love the coulda-been stories of characters that narrowly missed the cut and a chance at history, I have compiled my own list.
- Accountant (carries abacus and talks incessantly about Sarbanes-Oxley)
- Buffy (looks just like Smurfette but carries a wooden spike)
- Director (stocky with full beard, wears shorts, and quotes from comic books using issue number)
- Dot-com (rides a Segway everywhere and uses words like "monetize")
- Faith (looks just like Buffy but with black hair, dress, and shoes)
- Golf (wears loud, plaid pants)
- Lion Tamer (carries chair and whip)
- Lorelai (looks just like Smurfette but with brown hair, carries a coffee cup, and talks really fast)
- Mama (never seen, only referred to as "the smurf that took all of Papa's money in the divorce")
- Naughty (torso is pixelated)
- Nerdy (wears thick glasses and a pocket protector; constantly makes DND and BtVS references)
- Panhandler (carries a cardboard sign with a different message each episode, e.g., "Will Smurf for Food")
- Pimp (purple hat and pants and lots of gold)
- Stand-up (carries a microphone and tells inappropriate knock-knock jokes)
- Zoo (khaki hat and pants; has Australian accent)
Which did I miss?
