Despite an incredible skill and reputation regarding her engineering skills, Hayley is often very childish and lives in her head. Her large variety of interests, often involving food and exhibitionism (or some unfortunate combination of both), often end up with people around her become more victim than bystander.
Hayley is very skilled with summoned entities, gaining large amounts of power to her Golems. Her Drones, however, are where she shines the most, allowing for a steady stream of damage, healing and ammo refill, as well as gaining an ability midgame to endgame that allows her Drones to apply various special effects (knockback, stun, illusion). Hayley's offense and defense are quite poor, and she needs to be alive for her Drones to operate effectively, nor can she function well without them.
