The Badass Contaminator Heavy is a Maliwan trooper in Borderlands 3.



Badass Contaminator Heavies are a tougher version of the Contaminator Heavy, are resistant to Corrosive damage and attack with Corrosive damage.

Shock weapons are recommended in fighting a Badass Contaminator Heavy as they will always spawn with a shield. The pack on the Heavy's back is its weak point. Well placed shots will not only stun the Contaminator for a couple of seconds, but when damaged enough, will cause them to explode. This explosion can inflict considerable damage to any nearby enemies caught by the blast and leave behind a lingering pool of ice for a few moments.

Unlike a common Contaminator Heavy, the Badass Contaminator Heavy does not waddle and will break out into a jog towards the character. While it is still significantly slower than the character, its increased running speed will be coupled with the booster jets normal heavies use to move around, and it will more often create numerous simultaneous freezing puddles. It will almost always be in the midst of the character's attempts to move around and can be difficult to avoid if a character does not quickly leave the area that it is in.


  • There exists a dark variant of the Badass Pyrotech Heavy that can be found serving General Traunt on Nekrotafeyo or on the Slaughterstar 3000. Aside from their name and color scheme, they are functionally the same as their basic counterparts.
    • There also exists a Special Ops variant of the Badass Contaminator Heavy found at the Maliwan Blacksite at Midnight's Cairn, where they serve as guardsmen for the weapons project Valhalla. Aside from the name and color scheme, the Heavy retains their tactics.
