The Antagonist Pushes Your Hero to Change

Here's a question worth asking about your antagonist: are they only something your hero has to beat, or are they also the reason your hero has to change?

They might push that change on purpose, or by accident - either way, an antagonist who only functions as an obstacle is leaving one of their biggest jobs undone. They're also a mechanism for your hero's growth.

How it works

Your hero starts the story as one kind of person. To actually win, they have to become someone stronger, wiser, braver, or kinder than they were on page one. Something has to force that change, because people don't grow just because a plot needs them to - and very often, that forcing hand is the antagonist. The antagonist attacks the hero's weakness, and the hero has no choice but to fix it. The antagonist takes something away, and the hero finally learns what actually matters. The antagonist holds up a mirror, and the hero doesn't like what they see in it.

Connect it to the last lesson

This connects directly to the last lesson. When you write your villain as a real person with real goals instead of a flat obstacle, this growth tends to happen on its own - their actions genuinely push against your hero, and the hero simply can't stay the same person and still win.
