Modo, who first made his appearance in The Hunchback Assignments, is a young, disfigured spy trained to be the ultimate secret agent. Not only is Modo brilliant and strong, but he also has a special ability: he can temporarily take on the appearance of other people.

With the local sheriff recently deceased, the two travelers are suddenly put in charge of Ember's End law enforcement.
