Top 14 Toughest Bosses In The Entire Fallout Series

Ancient Behemoth – Fallout 4

As the oldest Super Mutant in the Commonwealth, the Ancient Behemoth is also the toughest one you’ll encounter in Fallout 4. Though it doesn’t possess the most devastating melee attacks or the highest damage resistance, the Ancient Behemoth still has 1900 health at level 95 with radiation immunity. Keep a safe distance, avoid those boulders and bring your biggest guns.
