Lady Deathstrike is a very single-minded Villain. At the start of the game, she will determine a single Hero as her target, and will hunt them down until they are taken out. It will be up to the team to keep the Hunted Hero safe. Luckily other Heroes in the Location can shield the Hunted Hero, taking damage in their place.
To help her in her obstinate hunt, Lady Deathstrike is aided by a trio of Henchmen who specialize in bringing pain to those around them. While Bonebreaker just steamrolls a Hero in his Location, Skullbuster and Pretty Boy are able to spread their fire to Heroes in adjacent Locations.
