I Villains sono delle persone che vogliono usare i loro quirk per beneficiare se stessi invece di aiutare gli altri. A differenza degli Heroes queste persone volevano utilizzare le loro UnicitÃ  per commettere crimini.Secondo Naomasa Tsuchauchi, nell'epoca attuale, il tasso di criminalitÃ  Ã¨ piuttosto basso a causa dell'ernome quantitÃ  di Heroes.
Liquids. Liquids do not hold their shape at room temperature. There is space between the atoms of a liquid and they move slightly all of the time. This allows you to stick your finger into water and pull it back out, letting the water fill back in where your finger once was.
Slack space is the unused space between the end of the actual file and the end of the the defined data unit (cluster). A cluster is the smallest unit of storage that the operating system can deal with. When a file is written, and does not occupy the entire cluster, the remaining space is slack space. For example, assume that the OS uses a 4k cluster and 512 byte sector, meaning it writes data in 4k increments made up of eight 512 byte sectors, regardless of the actual size of the file being written. This means that if a 2000 byte file were written to this cluster the remaining 2096 bytes would be slack.
