14 More Longest Boss Fights in Video Games

YGGRALITH ZERO (XENOBLADE CHRONICLES X)

Yggralith Zero is a world boss, which means that it’s an enemy that every single Xenoblade Chronicles X player is fighting against. It has literally millions of health bars, and each time a player defeats it, one of those health bars is depleted. It’s essentially a battle of attrition, expanded to a ridiculous scale, to the extent that completely killing Yggralith Zero can take as long as up to a week- and even that can vary, depending on how many players are playing the game and fighting the boss.
