Before deciding whether something is an outlier or not, we must check that it meets the requirements to be considered one:
- 1) Is it a big jump or drop in power? If a character with several planetary feats shows himself capable of destroying a star, we cannot consider him as an outlier, for the simple reason that the jump between categories is not extreme enough to be so, no matter how big the jump between energy values we attribute to him. Having previously performed an interquartile range, we already know the answer. If the character has very few feats, we can ignore this point.
- 2) Is it a unique or exceptional incident? Outliers occur rarely. If incidents of a similar level are repeated consistently over time, they are unlikely to be outliers. Usually, from the third incident onwards. If the character has very few feats, we can also skip this point.
- 3) Is the event unexplained and unjustified? If an extreme incident is not accompanied by any kind of explanation that justifies it, it is probably an outlier. But if it can be explained by means of some power-up, vulnerability or limiter, surely it is not. If Superman is wounded by a bullet, it's probably an outlier. But if Superman was under the influence of red sunlight or was previously weakened with kryptonite, it is not.
- 4) Does the event break the previously established power-scaling? Here we must take into account a number of factors, such as comparable characters possessing feats or statements of a similar level to the hypothetical outlier, the outlier not being supported by fights that might suggest a similar level, or subsequent events or statements that contradict it in some way.
- 5) Does the event break with the narrative of the work? Many times an outlier breaks with what has been previously established or shown in a work, creating inconsistencies that are difficult to resolve unless we invalidate one of the two events. If, for example, a character claims not to be able to dodge bullets, even though he was previously seen dodging them explicitly, we are faced with a contradiction where we will probably have to resort to the outlier.
If the answer to all or most of the above questions is "yes", we are probably facing an outlier. Recall that the decision to classify something as an outlier or not will always ultimately be an exercise of subjective interpretation.
