"...a trickster is a god, goddess, spirit, man, woman, or anthropomorphic animal who plays tricks or otherwise disobeys normal rules and conventional behavior."

In the context of liminality, the trickster is a very dangerous figure: “in a liminal situation where certainties are lost, imitative behavior escalates, and tricksters can be mistaken for charismatic leaders”[66]. This means that in their search for guidance, the individuals caught in the liminal situation might choose to follow a trickster, whom they confuse with a charismatic leader capable of “saving” them. Liminal periods that affect entire societies are characterized by the absence of a “master of ceremonies” (the leadership figures that are supposed to lead the initiands out of the liminal phase), which can in turn lead to the rise of tricksters into positions of power. When a trickster enters into a position of leadership, “liminality will not be restricted to a temporary crisis, followed by a return to normality, but can be perpetuated endlessly”[67]. This can be explained by three important characteristics of the trickster: his lack of a home (the trickster is, by definition, homeless and an outsider), lack of deeply felt human relations, and lack of existential commitments[68]. These traits cause the trickster to have no interest in solving the liminal crisis; “on the contrary, being really at home in liminality, or in homelessness, his real interest lies in its opposite, in perpetuating such conditions of confusion”[69]. On the other hand, the trickster is also a mime. “Imitation, whether in learning or in social activity, is only possible in so far as we are not aware that we are actually imitating…because as soon as we do so, imitation becomes a mere miming and would produce no effect in learning or no pleasure in involvement”[70]. Seeing as the trickster is incapable of “experiencing learning or the pleasure of sociability” as others do, he can be considered a mime rather than an imitator[71]. He thus appears to act just as everyone else does. With this in mind, there are “two characteristics [of the trickster] that under certain conditions could turn to be profitable, even [leading him to gain] unlimited and total power”: “his permanent state of exteriority helps him to think rationally and makes him a good mime: he cannot learn by genuine imitation but learns how to mime others and this produces laughter; thus he receives appreciation that otherwise he would never obtain”[72].
