I love the psycho mom.
She actually isn't in it too much compared to the others but I do like Zeno and Sylva, especially him for actually being a far better dad than Ging despite being a bad ass super assassin who raises a family of killers.
He died in the worst possible way for somebody like him. Disgraced and alone, crawling on the floor with nobody to pay him any mind.
Yeah he was always the most obsessed about staying pure to their "ant" nature while it seemed like Youpi and even Pitou were starting to come around a bit like the King was. I was actually waiting for something like him turning on the King after he realizes the Meruem is starting to change because of Komugi.
