Captain Olimar was noted in Pikmin 1 to wonder, a bit uneasily, why the Pikmin don't attack him, and speculated that they might see him as a "parental figure". An idea commonly held by fans is that Olimar's helmet antenna resembles a Pikmin stem, and that the Pikmin see him as one of their own or as some kind of "super Pikmin". Although wild Pikmin have never been observed to follow a leader, this explanation seems to be the most probable, and is further evidenced by the fact that Pikmin will imitate Olimar while idle, such as by blowing imaginary whistles.
