Term used to describe an atypical plumage, structural characteristic, or behavior in an animal or plant. Many martin landlords mistakenly believe that they have one or more Purple Martins that return to their colony sites, year after year, with aberrant white wing feathers.

Aberrant is a role-playing game created by White Wolf Game Studio in 1999, set in 2008 A.D. in a world where super-powered humans started appearing one day in 1998. It's the middle setting in the greater Trinity Universe timeline, chronologically situated about 90 years after Adventure!, White Wolf's Pulp era game, and several decades before the psionic escapades of Trinity/Aeon. The game deals with how the players' meta-human characters (called novas) fit into a mundane world when they most definitely are not mundane, as well as how the mundane populace react to the sudden emergence of novas.
