"I don't want to scare you, but, I'm an Adventure Sphere. Designed for danger. So, why don't you go ahead and have yourself a little lady break, and I'll just take it from here.
— Adventure Sphere • Portal 2

The Adventure Sphere is one of the Personality Constructs that appear in Portal 2. He is the second corrupted core to be dispatched by GLaDOS to be attached to Wheatley. He is found hanging on a wire, swinging about akin to a typical adventure hero swinging on a vine. 

While conversing with Chell, it is shown that the Adventure Sphere is more of a wannabe adventurer. He rattles on about accomplishing feats that are impossible considering his lack of mobility.


  • The Adventure Sphere, along with all the other corrupted cores, is voiced by Nolan North.
  • There is unused dialogue of the Adventure Sphere dissing both the Fact Sphere and the Space Sphere.
