I have to draw the fictional appearnce of boo for school and need a creative name for it.
I think a parody of the Wanted poster idea could work well. The physical description could be taken from Jem's elaborate outline of the squirrel-eating giant. His crimes would be the many and various accusations made about night-prowling and stabbing his father with scissors. The image could show Boo as the shy but human character he is shown to be later.
What about "The Gray Ghost Materializes." Boo has spent much of his life, and all of Jem and Scouts, metaphorically bound to the house by the chains imposed on him by family. The post could show a benovolent shadow going about the things Boo did in secret. Sew the pants, leaving the blanket during the fire, putting the items in the tree, saving Jem, and etc. With each action of the "ghost" Boo's corporeal self could grow bolder and more distinct in the poster illustrations.
I thought it would be fun to take a completely different point of view here. How about "The Exorcists" or perhaps "The Exorcised" (Ha!) This would be a (kind of) parody of one of the most iconic horror films of all time: The Exorcist (where a priest is able to bring a demon out of a little girl). In our case, both Scout and Jem would be the exorcists and Boo would be the exorcised spirit. Scout and Jem have, in fact, succeeded in bring Boo out of his house! The whole idea plays upon the thought of Boo being a sort of ghost (or at the very least, a monster) that needs to be drawn out of the Radley home.
Since Boo is initially described by Scout as a "haint," perhaps you could continue the motif of Boo as a presence rather than a fully realized person in your drawing. Maybe a sketch or drawing of Boo can be like a photograph that is overexposed. That is, the one image of Boo is centered and he is in one pose; however, coming from that somewhat solid image is another more impressionistic image that depicts Boo turned to the right sewing Jem's pants, placing them over the wire fence. On the left, Boo's impressionistic image can be carving the little dolls he places in the knothole of the tree. And, finally, emerging from behind Boo can be the man who defends the children against Bob Ewell.
Here's the title: Boo Radley: "To be a hain't or not to be a haint?" [play on Shakespeare's famous soliloquy from Hamlet]
How about "Boo Radley Behaves Badly"?
