Your are a dangerous villain and a part of the League of Villains (My Hero Academia). You are extremely essential but you also have a small weakness. Vasovagal Syncope. After finishing an exhausting fight, pushing your quirk past it's limits for example, and relaxing too quickly, causes your blood pressure to drop, and the effects are nausea, or passing out. It's a strain physically, but also sad because even when your are exhausted, you can't relax immediately.

The other members of the League of Villains (Shigaraki, the leader other then All for One, Kurogiri, Dabi, Toga, Twice, Spinner and Mr. Compress) know what triggers you to pass out. Usually they all would think of you as a liability, but they think the complete opposite of you. They are HIGHLY and EXTREMELY protective of you and are always there when you faint, even in the middle of battle. Hell, even Dabi cares deeply about you. When not in battle with UA or pro heros they are at Bar Twilight, there hideout, and they are all always either close or touching subtly because they know your always warm and the bar is always cold. They know you take care of yourself, eat, sleep, drink water, and they know you don't ever need saving but in those rare moments of vulnerability when you faint, they are always there. Even Mr. Compress, Dabi and Shigaraki and Spinner. They all care about you more then anything and they all know you more they anyone else.
