Summary
A lesser form of Acausality, this ability is attributed to characters who can interact with others as per the laws of cause and effect but will not be affected by events that happen to their past selves. Hence, if they were killed in the past, it would not affect them in the future. In addition, these individuals would still retain any knowledge they gained in the past even if the events of a timeline were revised. It is thus possible to defeat these characters through conventional means, but it's virtually impossible to do so by killing them in the past with Time Travel or a similar ability.
