Well, here's one I'd like to see:
Mephistophlings: These insidious creatures are minor devils are an amusing and annoying creation of their namesake, Mephistopheles, Lord of the 8th (See the Book of Vile Deeds). They delight in causing pain and suffering, leaving a trail of it wherever they go.
Each Mephistophling appears to be a miniture, bat-winged devil about the size of a halfling resembling Mephistopheles. While the similarity to Mephistopheles is noticeable, there is enough variation in their appearances that you can tell them apart. They enjoy hurling about their Hellfire-themed Vile Magic Missiles or Scorching Rays while they cackle with glee. Most Mephistophlings carry a small, 3-tined, pitchfork-like spear and wear ratty black garments (much like their namesake).
I plan on using a group of these little guys (mechanically they are half-fiend halfing Sorcerers) on my group soon, and I'd love to have a picture of a couple of them.
