There's the r2d2 and c-3po tags that appeared recently. Those are a subset of the star-wars tag.
Before I (or we) start to re-tag all star-wars question with a character tags I would like to discuss this.

Second, should we use a princess-leia or leia-organa-solo? should we set the other as a synonym?
And what about darth-vader/anakin-skywalker
And senator-palpatine/darth-sidious/the-emperor/emperor-palpatine/palpatine
