“My deadliness is equaled only by my beauty.”
She may look just like a beautiful Wild West can-can dancer, but Calamity Drone is one tough and dangerous robot. Whether she’s wielding an old-fashioned rifle or a new-fangled flamethrower, her itchy trigger finger makes her tend to blast first and ask questions later.
Calamity has been waiting a long time for some Master Builders to show up in her saloon so that she can fulfill her prime directive and capture them for Lord Business. Little does she realize that the most-wanted Master Builder of them all has been right under her nonexistent nose the whole time!
