Queen iOsaur & King Bobo | Opponent in Borderlands 3 Borderlands 3 guide, walkthrough

Last update: 27 September 2019

This page of the guide to Borderlands 3 describes a boss fight with iOsaur, Queen of the Scaleon and King Bobo the Almighty. These optional bosses aren't that easy to defeat. Our walkthrough for this battle will show you how to play this battle smart to reduce the risk of getting defeated.

iOsaur and King Bobo are large beasts you face in The Terradome. This fight happens in the final part of Rumble in the Jungle side quest available in the Voracious Canopy region on Eden-6.

The most important information about this fight is that you don't have to stay inside The Terradome. The entrance to this location is still open - you can leave at any time. This is a great way to attack the bosses from a distance or take a break from the fight. iOsaur and Bobo can also exit from the dome, but they rarely do that.

Another important information is that the Queen iOsaur and King Bobo are fighting not only with you but also with themselves. If you want to, you can leave the dome and wait until they weaken each other and then go back to the arena.

Remember to eliminate the bosses one by one - you can eliminate them in any order. Queen iOsaur looks like a T-Rex. She is able to shoot bullets and spit acid - avoid both attacks by running to the sides. She also has only one red health bar.

King Bobo likes to jump to the upper shelves in the dome and attack from the top by throwning acid balls. He can also hit the ground and create a shockwave - run to the sides. This boss has two bars - yellow and red.

There is a high probability that you will get knocked down by one of the bosses. Luckily, you can shoot Squire Jabbers running around the arena. Try to kill them with the most powerful weapons to get Second Wind and resume the fight.

The bosses dop credits, eridium and random gear. You also get a reward for completing Rumble in the Jungle quest - XP and a lot of credits.
