25 Famous Games Featuring Hidden Bosses

I’ve always loved hunting for hidden bosses in games. It’s a classic thing developers do to really reward players who explore everything and get good at how the game works. These bosses aren’t just going to fall into your lap – you usually have to find secret passages or complete super obscure side quests you’d probably miss on a normal playthrough. They’re like the ultimate test of skill, pushing you to truly understand all the game’s systems. And the best part? Beating them usually gets you awesome, unique rewards and sometimes even unlocks more of the story. I’m going to walk you through some of the most iconic games with these hidden, incredibly tough enemies.

‘Elden Ring’ (2022)

Elden Ring, created by FromSoftware and published by Bandai Namco Entertainment, is a large open-world game with a particularly difficult optional boss: Malenia, Blade of Miquella. Players can find her hidden in the Elphael area, but first they need to find the two pieces of a special medallion and make their way through a dangerous, snowy landscape. Malenia is famous for her incredibly fast attacks and her unique ability to regain health whenever she hits you. Beating her is seen as a major accomplishment for fans of action and RPG games.

‘Bloodborne’ (2015)

Bloodborne is an action role-playing game made by FromSoftware and published by Sony. It has a hidden final boss called the Moon Presence, which players can only fight after finding and using three special items. These items are hidden throughout the game world and require players to make certain choices during gameplay. Beating the Moon Presence unlocks a special ending that provides further insight into the powerful, otherworldly beings that control the game’s universe. The boss fight is visually striking and serves as a challenging culmination of the game’s fast-paced combat system.

‘Final Fantasy VII’ (1997)

Originally released for the PlayStation, ‘Final Fantasy VII’ from Square is a beloved classic. A notable feature of the game is the inclusion of the incredibly difficult Ruby Weapon and Emerald Weapon, optional bosses that appear later in the game. Players will find them in the desert and underwater, but only after making significant progress in the story. These enemies have a huge amount of health and require specific strategies to defeat. Successfully beating them rewards players with rare items, proving they’ve truly mastered the game’s combat.

‘Dark Souls III’ (2016)

FromSoftware created ‘Dark Souls III’, and Bandai Namco Entertainment published it. The game includes a hidden area, Archdragon Peak, which players can only reach by using a specific gesture at a particular spot. This leads to a fight with the Nameless King, often considered the hardest boss in the original game. The battle has two parts: first, you fight him while he’s riding a storm drake, and then in close combat. This encounter reveals important details about the gods and their history within the game’s story.

‘Kingdom Hearts II’ (2005)

Square Enix and Disney teamed up to create ‘Kingdom Hearts II’. The game features challenging secret battles against tough opponents: Sephiroth from ‘Final Fantasy’ appears in Hollow Bastion, and later versions added the incredibly strong Lingering Will in the Keyblade Graveyard. Both of these bosses are much harder than the game’s final boss and demand skillful play. If you manage to defeat them, you’ll earn powerful keyblades and other rare items.

‘The Legend of Zelda: Breath of the Wild’ (2017)

Nintendo created ‘The Legend of Zelda: Breath of the Wild’ for both the Switch and Wii U. Although the game has several bosses as part of the main story, the expansion added Monk Maz Koshia as a hidden, ultimate challenge. Players need to finish the Champions’ Ballad quest to fight him in a complex, multi-stage battle. He uses different elemental powers and illusions to really test Link’s skills. Many players consider this fight a standout moment, especially those who enjoy classic boss battles within the game’s open world.

‘Persona 5 Royal’ (2020)

Developed by P Studio and published by Atlus, ‘Persona 5 Royal’ is an enhanced version of the original game. It includes a challenging secret boss battle against Lavenza in the Velvet Room, which becomes available near the end of the game. To unlock this fight, players need to progress to a certain point in the story and max out specific social connections. The battle itself is quite demanding, requiring players to inflict particular types of damage each turn to avoid immediate failure. Successfully defeating Lavenza proves mastery of the game’s intricate persona fusion and combat mechanics.

‘Hollow Knight’ (2017)

Team Cherry created and released ‘Hollow Knight’ on multiple gaming systems. The game’s real final boss, the Radiance, is challenging to reach, requiring players to first get the Void Heart. To unlock the fight, players need to use the Dream Nail on the main boss. The Radiance attacks with a barrage of quick projectiles and beams of light, demanding skillful dodging. Winning against her delivers the most complete ending to the story and resolves the fate of Hallownest.

‘NieR: Automata’ (2017)

Developed by PlatinumGames and published by Square Enix, ‘NieR Automata’ features a secret boss fight against Emil. Players unlock this encounter by completing quests focused on his backstory. It’s a challenging fight, requiring a high character level and finding a hidden area. The battle itself is fast-paced and filled with a constant stream of attacks, showcasing the game’s ‘bullet hell’ style. Ultimately, it provides a moving finale for a character fans have met throughout the ‘NieR’ series.

‘Cuphead’ (2017)

Studio MDHR created ‘Cuphead’ as a loving homage to old-fashioned cartoon animation. The game features hidden challenges within boss fights that are unlocked by doing certain things during normal gameplay. For instance, how you fight the Root Pack can change if you choose not to attack the onion enemy. These secret additions introduce new attack patterns and make the game even more challenging, offering extra depth for players who like to explore how each fight works.

‘Super Mario RPG’ (1996)

Developed by Square and released by Nintendo for the Super Nintendo, ‘Super Mario RPG’ includes a secret boss named Culex. Culex originally appears in the ‘Final Fantasy’ series and can be found behind a locked door in Monstro Town – you’ll need a Shiny Stone to unlock the fight. The battle itself feels like a classic RPG, with music and gameplay elements from that time period. Culex is now well-known as one of the most memorable crossover bosses in video game history.

‘Castlevania: Symphony of the Night’ (1997)

Konami created and released ‘Castlevania: Symphony of the Night.’ Hidden deep within the Inverted Castle’s Floating Catacombs is a challenging optional boss named Galamoth. This enormous enemy has a lot of health and attacks with powerful lightning. If you manage to defeat him, you’ll unlock the Gas Cloud form for Alucard. This secret encounter is a great example of the rewards players receive for exploring the game’s intricate level design.

‘Sekiro: Shadows Die Twice’ (2019)

FromSoftware created and Activision published the game ‘Sekiro: Shadows Die Twice’. The Demon of Hatred is a challenging optional boss that appears near the end of the game, after certain events change the world. Unlike most enemies in Sekiro, which focus on sword combat, this boss fights more like those found in the ‘Dark Souls’ series. Players need to rely on their prosthetic tools and quick movement to dodge its powerful fire attacks. Defeating the Demon of Hatred also concludes the story arc for a key supporting character.

‘Monster Hunter: World’ (2018)

Capcom created and released ‘Monster Hunter World’, which included unique crossover events featuring challenging hidden bosses like the Ancient Leshen and Behemoth. These monsters demand strong teamwork and defined roles to overcome, and their battles incorporate gameplay elements from other popular RPGs. They continue to be incredibly difficult fights, even for experienced players aiming to collect rare items.

‘The Witcher 3: Wild Hunt’ (2015)

CD Projekt Red created and released ‘The Witcher 3: Wild Hunt’. The game’s main story has plenty of enemies, but the expansions added secret boss fights, such as those against the Caretaker and the powerful vampire Dettlaff. Finding and defeating these bosses requires players to prepare carefully with potions and magical signs. The Caretaker is particularly memorable for its creepy appearance and unusual ability to heal, which often catches players off guard. These challenging encounters make the game’s monster hunting even more engaging and diverse.

‘Final Fantasy X’ (2001)

As a huge ‘Final Fantasy X’ fan, I have to say this game is incredible! It originally came out for the PlayStation 2, and later versions – the international and remastered ones – added even more challenge with these things called Dark Aeons. But the real kicker? Penance, the ultimate hidden boss. You can only fight Penance after you’ve beaten all the Dark Aeons all over Spira. And let me tell you, that fight is a marathon! It seriously takes over an hour, and you need to have absolutely perfect gear and a really, really solid grasp of the turn-based combat to even stand a chance.

‘Borderlands 2’ (2012)

Gearbox Software created ‘Borderlands 2’, and 2K Games published it. The game includes challenging raid bosses, like Terramorphous the Invincible, which are best tackled by teams of four players. Terramorphous lives in a secret arena unlocked after finishing the main story. This fight is notoriously hard but rewards players with some of the game’s most powerful items. Many players dedicate hours to repeatedly battling these bosses to improve their characters’ abilities and gear.

‘Devil May Cry 5’ (2019)

Capcom created and released ‘Devil May Cry 5’. Skilled players can unlock a secret boss fight surprisingly early in the game by defeating Urizen during the prologue. This is extremely challenging the first time you play, as Urizen has a lot of health and strong defenses. If you succeed, you’ll trigger a secret ending and finish the game right then and there. This special outcome is designed as a reward for expert players, especially those tackling the harder difficulty levels.

‘Star Fox 64’ (1997)

Developed and released by Nintendo for the Nintendo 64, ‘Star Fox 64’ includes a peculiar hidden boss called the Slot Machine. Players can find it in the secret stage, Out of This Dimension, but reaching it requires skillful flying in the Asteroid Field level. The boss itself is a massive slot machine – players win by matching symbols, which can either damage the machine or reward them with items. This bizarre fight is one of the most well-known secrets in the entire ‘Star Fox’ series.

‘Undertale’ (2015)

Toby Fox created and released ‘Undertale’ all on his own. The game includes a famously challenging secret boss battle against Sans, but you can only encounter him if you choose a specific path called the ‘Genocide Route.’ This route forces players to defeat every enemy in the game before they can finish it. The fight with Sans is known for being incredibly difficult and for breaking many of the usual rules of the game’s battle system. It’s designed to be a consequence of the player’s choices and actions throughout the game.

‘God of War Ragnarök’ (2022)

Santa Monica Studio developed and Sony Interactive Entertainment published ‘God of War Ragnarök’. Once players finish the main story, they can challenge two particularly difficult optional bosses: King Hrolf Kraki and the Valkyrie Queen Gna. These fights demand skillful dodging and parrying to overcome their complicated attacks. Beating them is essential for players who want to experience everything the game has to offer and fully conclude Kratos and Atreus’s story.

‘Dragon Quest XI S: Echoes of an Elusive Age’ (2017)

Developed and published by Square Enix, ‘Dragon Quest XI S: Echoes of an Elusive Age’ offers a complete gaming experience with tons of extra content after the main story. This includes a secret battle against the incredibly strong Timewyrm boss. To unlock this fight, players must finish the Tickington side quests and journey through locations from previous Dragon Quest games. Defeating the Timewyrm, which is designed to challenge even max-level parties, earns you the highest possible in-game achievement.

‘Octopath Traveler’ (2018)

Developed by Acquire and Square Enix and published by Square Enix, ‘Octopath Traveler’ features a hidden final boss named Galdera. Unlocking the fight requires completing side quests across the entire game world. Once players reach the Gate of Finis, they can battle Galdera, a two-stage boss, using all eight of their characters. This battle is much more challenging than anything else in the game and serves as a way to tie together the individual stories of the eight main characters.

‘Bayonetta’ (2009)

PlatinumGames created the game ‘Bayonetta’, which Sega published. Players who buy a very costly item from a character named Father Rodin can unlock a secret boss battle against him. Many players consider this fight the most difficult in the game because of Rodin’s incredible speed and strength. Unlike other bosses, his health isn’t displayed for much of the battle. If you manage to defeat him, you’ll earn the game’s strongest weapon for Bayonetta.

‘Chrono Trigger’ (1995)

Square created ‘Chrono Trigger’ for the Super Nintendo, and later versions included a hidden boss called the Dream Devourer. Found in the Time Vortex, this boss battle connects the game’s story to its sequel, revealing what happens to some of the characters. The Dream Devourer is a powerful combination of Lavos and a key character, and players need strong equipment to win. This addition expanded the game’s story and gave dedicated fans a deeper understanding of the world.
