Famine

Famine is a Harbinger that can appear in all environments of Chapter 1.

Phase 1

 * If Isaac is to the left or right of Famine, he charges horizontally across the screen. He continues this charge off-screen and reappears from the opposite end of the screen.
 * Spawns a Pooter with a limit of 2.
 * If this limit is reached Famine will move to try to position himself horizontally of Isaac so he can charge at him.
 * Any Pooters caught in Famine's charge will be killed.

Phase 2
When Famine takes a sufficient amount of damage, his body and horse explode and vanish while only his head remains. Famine deals a whole heart of contact damage in both phases and during his charge.
 * Famine's head behaves similarly to a Maw, slowly moving towards Isaac, and occasionally stops to fire three projectiles in a spread at Isaac.

Champion Versions

 * Blue: Charges more often and veers towards Isaac (similar to the Dark One). He can do this attack regardless of whether Isaac is to his sides or not. He will shoot six bullets in all directions instead of summoning Pooters. In Phase 2, he will spit out a cluster of bullets instead of a triple shot, similar to Monstro's attack, with a lower rate of fire than his non-champion version. Will always drop a Soul Heart upon death.

Trivia

 * Famine does a full heart of damage with his charge attack and contact damage under normal conditions.
 * Famine appeared in the original The Binding of Isaac.
 * Famine is one of the Four Horsemen of the Apocalypse mentioned in the Bible. However, in the Bible, Famine is depicted as riding a black horse rather than the tan horse seen in-game.
 * A famine is the scarcity of food over a large area, which can explain Famine's emaciated appearance.
 * Famine is shown with pupils in his Rebirth artwork, which is absent in his original artwork.
