All the bosses in Borderlands 4

The bosses in Borderlands 4 are an essential part of the campaign, as each encounter is full of tension, strategy, and moments of pure adrenaline. Set on the planet Kairos, the game immerses you in a territory marked by wars, failed experiments, and powerful figures who serve the dreaded Time Lord.

Each fight is a different challenge, with enemies ranging from colossal mutant creatures and fanatical warriors to entities with temporal abilities. To avoid getting lost in this long journey, here you can find all the bosses in Borderlands 4 and how to defeat each one.

Warden Scathe

Mission: Guns Blazing

The initial confrontation against Warden Scathe serves as an introduction. He fires energy blasts and summons small synthesizer robots. The trick is simple: maintain constant movement and take advantage of an elevated walkway to the left of the arena. This space provides cover against his direct beams and opens up gaps to attack safely.

Splashzone 

Mission: Recruitment Drive

Splashzone features short but aggressive combat. This Ripper leader prefers melee attacks and has a mechanized arm capable of causing earthquakes in the arena . The key here is to never stay close for too long . Use the edges of the camp to keep your distance while neutralizing the minions he summons.

Horace

Mission: Down and Outbound

Horace is quite similar to Scathe, but the main difference is his energy shield, which is vulnerable to electrical damage. As soon as the shield falls, his behavior changes and he chases you around the arena in melee attacks. Taking advantage of this moment of vulnerability is essential to shortening the fight.

The Oppressor

Mission: A Lot to Process

Among the bosses in Borderlands 4, The Oppressor is one of the most visually impressive. It's a colossal flying machine that bombards the area with missiles and lasers. Grenades are almost ineffective here; the strategy is to use long-range weapons and move between the machines that provide cover. Quick reflexes are needed to escape the area attacks.

Bio-Bulkhead

Mission: One Fell Swoop

The experiment gone wrong resulted in Bio-Bulkhead, a brutal monster with devastating melee attacks. The key to this fight is the Locust Canisters scattered around the arena. You need to grab these canisters and throw them at him . This breaks his temporary immunity, opening up an opportunity to inflict significant damage. Without this, the fight can drag on for a long time.

Idolator Sun

Mission: Rush the Gate

Idolator Sol is one of the Borderlands 4 bosses that requires the most attention. He erects pillars, summons guards, and even absorbs these same allies to regain health . The rule is simple: never leave the minions alive too long. Also, pay attention to the green pillar that always carries a Locust Canister. Using this item against Sol is key to removing his immunity and advancing in the fight.

Skyspanner Kratch 

Mission: Shadow of the Mountain

This gigantic bat guards the caves of the Terminus Mountain Range. Kratch is agile and has smaller troops that attack in swarms. Sonic attacks are the biggest problem, as they hit multiple times in quick succession. Being above level 15 before the confrontation is almost mandatory, as the damage he inflicts is very high.

Vile Lictor 

Mission: His Vile Sanctum

In the Borderlands 4 boss list, Vile Lictor is perhaps the one that most tests reflexes. He uses the Hundred Hands ability, launching targeted projectiles . In addition, he summons Spectral Walls, some sweeping, others in segments. The best tactic is to stay focused and move constantly. His teleportation can be confusing, but never lose sight of him.

Driller Hole

Mission: Unpaid Tab

In the underground prison of Crestadura de Carcádia, you face Driller Hole, which functions as a kind of artillery. Its attacks cover large areas and almost always deal fire damage. During the fight, some Rippers appear to distract you, but the real danger comes from its incendiary bombardments . After defeating it, you can save a secondary character by activating levers and destroying pipes in the ceiling.

Callis, the Ripper Queen 

Mission: Her Flaming Vision

Callis moves unpredictably, jumping, spinning, and summoning bombs. Flaming orbs travel across the ground and return to her, while floating mines explode after a few seconds. When her health reaches half, the boss climbs the walls and projects laser nets that immobilize enemies. The secret is to identify the patterns little by little and eliminate minions quickly.

Moon-Maddened Callis

Mission: Another Day, Another Universe

This variation of Callis occurs on a floating rock above Elpis. Besides the already known attacks, the biggest risk is falling off the arena. If this happens, it's necessary to grab on immediately to avoid losing progress. During phase transitions, she covers the field with area-of-effect attacks, requiring quick and precise movements.

The Lord of Time – Initial Phase

Mission: The Timekeeper's Order

The confrontation against the Lord of Time is lengthy and divided into three life segments: shield, armor, and body. He fires multiple projectiles, summons golden walls, and even blinds you with flashes of light. When he launches you into the air, you must glide through the air to reach safety.

The Lord of Time – Final Phase

Mission: The Timekeeper's Order

After defeating the first version, a second, even more brutal one appears. It generates fragments that scatter and explode, in addition to melee attacks that throw you far away. If you fall out of the arena, grab on immediately. The aerial attacks are even more dangerous, requiring quick reflexes. This confrontation may be the longest of all the Borderlands 4 boss fights.

The secret boss

Mission: Secrets of the Vault

After the battle against the Lord of Time, there remains the confrontation against an unnamed enemy, whose name has not been revealed by the developer. He summons devastating tornadoes that rapidly drain life. The only way to neutralize this attack is to get close, interrupt the summoning, and only then retaliate. It's a final test of endurance, where careful positioning is worth more than aggression.

With this guide, facing the bosses in Borderlands 4 becomes less intimidating, and each battle becomes a milestone of overcoming challenges within the campaign.
