"That should do it."
Only a few more minutes had passed, but Ken was already knocked out on the ground.
For someone who enjoyed the feeling of superiority like Ken, taking away their Special Ability was equal to torturing him for the rest of his life. That being said, Leo made sure to add some pummeling for good measure.
Although he also broke some bones as a finishing touch, Leo made sure they were clean breaks that wouldn't leave permanent damage if treated properly. If he went any further, killing Ken would have been a far more merciful choice.
Naturally, Leo didn't enjoy beating down helpless people. However, he needed to do enough so that a helpless case like Ken could get the message and go the other way.
Leo also wanted to directly spill it out for him, but unfortunately, this wasn't a one-sided play. He couldn't just tell his victims that he was doing all of this to help Aurora, or that he was punishing them for exploiting her.
