Outlier

An outlier is an event or incident that is considered to be completely and irreconcilably inconsistent with a character, entity, group, or series' normal displayed level of power. Outliers are generally regarded as unusable in OBD debates. However, all effort should be made to try to reconcile outliers with other  canon information, and only the most extreme examples should be classed as completely unusable. Often there is  disagreement on exactly what constitutes an outlier, and things that are considered an outlier by some might not be considered to be one by everyone. Careful judgement should be used in all cases.

Examples of (generally accepted) outliers:

-  Post - Crisis Superman defeating Dominus, a  multiversal  cosmic being -  Hulk destroying a  dimension with a  thunderclap -  Master Roshi destroying the moon - Fuko dodging a  laser early on in Flame of Recca, which would give her  FTL  reactions, when even later in the series the strongest characters are only arguably  hypersonic <span style="color:rgb(51,51,51);font-weight:normal;">-  Shanks<span style="color:rgb(51,51,51);font-weight:normal;">' arm being bit off by a random sea king in  One Piece <span style="color:rgb(51,51,51);font-weight:normal;">-  Samurai Jack<span style="color:rgb(51,51,51);font-weight:normal;"> defeating an enemy wielding a weapon that was  supposedly<span style="color:rgb(51,51,51);font-weight:normal;">  universal<span style="color:rgb(51,51,51);font-weight:normal;"> in power <span style="color:rgb(51,51,51);font-weight:normal;">-  Emperor Palpatine<span style="color:rgb(51,51,51);font-weight:normal;"> being kidnapped by normal troops led by Admiral Zaarin in  Star Wars <span style="color:rgb(51,51,51);font-weight:normal;">-  Batman<span style="color:rgb(51,51,51);font-weight:normal;"> hurting  Darkseid<span style="color:rgb(51,51,51);font-weight:normal;"> with a kick <span style="color:rgb(51,51,51);font-weight:normal;">- Deathstroke defeating the JLA in  Identity Crisis<span style="color:rgb(51,51,51);font-weight:normal;"> (featuring a bunch of traps they would never realistically fall for and so much PIS on the JLA's side it was pathetic) <span style="color:rgb(51,51,51);font-weight:normal;">-  Orion<span style="color:rgb(51,51,51);font-weight:normal;"> and  Etrigan<span style="color:rgb(51,51,51);font-weight:normal;"> each destroying 1/5th of a universe <span style="color:rgb(51,51,51);font-weight:normal;">-  Zatanna<span style="color:rgb(51,51,51);font-weight:normal;"> defeating a universal+ being <span style="color:rgb(51,51,51);font-weight:normal;">-  Captain America<span style="color:rgb(51,51,51);font-weight:normal;"> hurting  Onslaught <span style="color:rgb(51,51,51);font-weight:normal;">-  Iceman<span style="color:rgb(51,51,51);font-weight:normal;"> defeating  Oblivion <span style="color:rgb(51,51,51);font-weight:normal;">-  Storm<span style="color:rgb(51,51,51);font-weight:normal;"> channeling the entire power of a galactic core <span style="color:rgb(51,51,51);font-weight:normal;">-  Thor<span style="color:rgb(51,51,51);font-weight:normal;"> containing a blast powerful enough to destroy 1/5th of the universe
