(During setup, choose another character whose name contains Han Solo. This character's point cost X is 1/2 the printed cost of the chosen character. An opponent sets up this character along with his or her squad. This character cannot be activated, cannot move, and does not count as a legal target. Its space cannot be entered, but it provides cover. If an ally ends its turn adjacent to this character, you may immediately remove this character from play and place the chosen character in its space. The newly placed character cannot activate this round.)
Versatility takes place AFTER setup. There is no precedent to go back to a previous step (in fact, there is precedent that you DON'T do that unless specifically told otherwise in Force Essence), so the time to "choose another character whose name contains Han Solo" has passed, and you can't go back to it. That means that Hansickle costs X, and when you end your turn adjacent to him you remove him from play and place nobody, since "the chosen character" is a null value; none was ever chosen, so you don't get to place anyone.
We might want to add a line somewhere to say that if X is not defined it defaults to 0 (other games that use X for things like this usually have this rule), so Hansickle would cost 0 points, but release no one.
