The Dark Souls trilogy, developed by FromSoftware, harbors some of the most dangerous and aggressive enemies in video game history. The most domineering, powerful bosses across the Dark Souls trilogy are among the most challenging bosses in gaming, at least when it comes to high-profile modern projects. Even ignoring the bosses from Demon's Souls, Bloodborne, and Sekiro, The Dark Souls trilogy will be more than enough to test any hardened gamer's patience.
