The hadron has not been yet discovered

Once you defeat all four of the Greybaym bosses and then the challenger underneath the shadow version of you, you will get the Hadron. You will also be able to use the parts of a Hadron.

A hadron is a composite particle made up of quarks. Use the links below for more information.

The Large Hadron Collider will work mainly with protons - hence the name (the proton is a kind of hadron). It will also do some experiments with other particles, for example, with certain atomic nuclei.

the hadron collider has a diameter of 3.8 metres and has a circumference of 17 miles (27 kilometres)
