15 Video Game Bosses You Can’t Defeat No Matter What You Do

Yellow Squadron (1st Battle) – Ace Combat 4

In Ace Combat 4: Shattered Skies, things are going fairly well for you until Yellow Squadron shows up. Not only are they pretty much impossible to hit thanks to their crazy AI but none of them take damage. Even later on when their AI has been somewhat balanced, they’re still invincible. Hitting them once ends the second encounter quickly and earns you some fairly surprised dialogue from your side and the enemy’s.
