Villain Cape mission: the story was you could not wear a cape until you took down a hero at level 20. My stalker and dominator villain died many times on the mission and I usually played solo and I struggled. My dominator villain often died a lot and likely died in a stiff breeze. I still loved those characters.
I finally traveled to the top of a building, stun the hero, knock back, they drop to one health point and I finish the job. I figured that out by accident the two weeks I was home with pneumonia one summer.
