Yu-Gi-Oh! VRAINS/Nightmare Fuel


 * The first episode has one of the Knights of Hanoi destroying people's avatars with his monster. While it's said that their accounts are deleted, it doesn't change the fact that people are running away in terror from the Knights of Hanoi and look to be killed. It also doesn't help that Ignis says getting hurt in Link VRAINS could affect your physical brain, causing mental damage.
 * Yusaku himself is already a walking example of this: he's very unpleasant, is a No-Nonsense Nemesis driven by rage and hatred, and treats Dueling as a means to get Revenge on the Knights of Hanoi. As some viewers noted, Yusaku is what Yuya would've become if he embraces brutality over entertainment. Even his "Reason You Suck" Speech as Playmaker, while simple, really shows how cold-hearted he is, topping the likes of Jack and Reiji in this department:
 * After Yusaku defeated the Knight of Hanoi in a duel, it tried to self-destruct in an attempt to take Yusaku with him, and would have succeeded if Ignis hadn't devoured him and destroyed his avatar then and there. The way Ignis ate the Knight is also pretty unsettling.
