Minotaur –  Half-man, half-bull; guardian of the violent souls in the 7th Circle of Hell

Biblical Giants (Nimrod, Ephialtes, Briareus, Tityos, Typhon, Antaeus) – Guardians of the 9th Layer of Hell; all are bound in chaisn and standing above a cliff overlooking the frozen lake, save for Antaeus, who lowers Dante and Vigil into the pit

Satan – King of Hell; captured in the frozen lake for committing the ultimate sin of the attempted usurpation of God; flaps his wings in an effort to escape his imprisonment, but only ensures it by generating the icy floe that keeps he and the worst sinners in the 9th Layer of Hell eternally frozen

he had three faces: one in front bloodred;
and then another two that, just above
the midpoint of each shoulder, joined the first;
and at the crown, all three were reattached;
the right looked somewhat yellow, somewhat white;
the left in its appearance was like those
who come from where the Nile, descending, flows.
