Ottsel Leader is one of the three Precursor ottsels seen in Jak 3 along with Ottsel Surfer and Ottsel Dummy. As his name suggests, he is the leader of the Precursor trio, appearing to be the most intelligent. He is soft-spoken, comes off as wise, yet retains a somewhat mischievous streak, as he has been known to transform people into ottsels as a way of granting favors with little more than a "Be careful what you wish for" as a warning.
