Braixen have long been mistaken for witches, but not until they become Delphox can they perform true magic, for a Braixen's complex, illusory tricks are easily explained by science. Although Braixen's performances take many different shapes, but it is a single trick; through quick movements and smoke messages, the Braixen first summons many others of its species, then disguises many as one.
When a Braixen spots a signal for illusionist aid, it is required by custom to run as far as necessary to each other's aid, provided that they can do so without being spotted. This restriction tends to attract equal numbers of Braixen regardless of weather and location, for differences in visibility typically cancel out; areas where the smoke can be seen from far away must equally reduce their ability to hide, while smoke which does not carry far does allow the Braixen who can see it to easily reach their signal. Once there, the Braixen both communicate with their trick's leader through smoke, allowing it to see what it can not, and to use it as a shield to switch places whenever the illusion calls for it.
A Braixen who refuses to come when summoned, or who calls to lead shows too often and aids them too rarely, can develop a bad reputation and becomes unable to perform magic. Indeed, it is through one such Braixen's revenge that humanity has learned these pokemon's secret. Yet knowing the theory behind the Braixen's secret and being able to spot it in progress are two very different things. Since humans have discovered their trick, Braixen have focused their efforts on performing too fast for the naked eye to spot; the challenge of catching them has made their shows more popular than ever.
