How it works

Each shapeshifter writing prompt here gives a character the same power, changing shape, and a different problem with it. The line underneath names the tell, the detail that gives the shifter away, and what the change costs.

Read the full guide

Four problems with one power

The first change is a surprise: a swimmer wins a race as an otter and cannot keep the medal. Hiding it is a long strain, as for the girl who changes when she laughs and so never does. Stuck in the wrong shape comes with a deadline. A shifter among us is told by the people who suspect.

Shapeshifter myth writing prompts

Thirteen prompts borrow from old stories, and the group Out of myth and folklore holds them: a selkie's sealskin, a fox with a second tail, a kelpie that keeps its hooves in human form, a sea god who must be held through every change. The line under each says what the old story holds.

  • Choose the tell before the plot. A shifter with no tell cannot be caught, and then nothing is at stake.
  • Let the other shape want things. A girl stuck as a crow cannot leave a pie on a windowsill alone.

Questions and answers

What is a shapeshifter in a story?

A character who can change physical form. In folklore the change is sometimes chosen and sometimes forced, and it often hangs on a thing that can be lost or stolen: a selkie's seal skin, a swan maiden's feathered coat.

Which shapeshifters come from myth?

Many. This list borrows the selkies of Scotland's Northern Isles, the kitsune and tanuki of Japan, the kelpie of Scottish lochs, the púca of Celtic folklore, the Slavic leshy and Proteus, the Greek old man of the sea.

How do I write a shapeshifter character?

Decide what sets off the change, what never changes and what the change costs. Each prompt supplies the last two. A bank teller who changes only in the shower hums lower than any teller could, and that is his tell.

Are these prompts scary?

No. Nobody is hurt and no shifter here is a monster. The trouble is comic or a little sad: a shifter stuck as a library book is read aloud to a toddler twice a night.
