Seth is a character and miniboss from Hollow Knight: Silksong. He is an average-sized bug, with two long Antennae. The upper half of his torso is covered by a Cloak either made of green leaves or made to resemble green leaves. In addition to a longpin, he wields a round, copper-colored Shield. He uses his shield as much as for offense as for defense, throwing it around in a manner sometimes likened to Captain America.
Seth guards a nature shrine, and he announces himself and his duty as Hornet (Hollow Knight) approaches. Seth will never strike preemptively, and only engages Hornet if she challenges him, attacks him or tries to walk past.
Seth is named in honor of Seth Goldman, a devoted Hollow Knight fan who passed away due to Ewing sarcoma a type of cancer.
