Ivan Von Shellshocktonberg, better known as Shellshock, is the first exterminator you encounter and he is the only one you will fight outside the Combat Dome. This robot, worth six and a half million bolts, has the specificity of having a coffee machine chip instead of a brain thus making him totally insensible to pain. To get rid of him, you will have to fight him several times on his ground, on the planet Kronos.
