Kang
Multiversal variants of Nathaniel Richards, also known as Kang the Conqueror.
They are considered the highest risk category by the Time Variance Authority, due to the frequency with which Kangs discover time or multiversal travel, making them a serious threat to the stability of their native timelines.
At one point, a multiversal war broke out between Kangs from different timelines who were all seeking to becoming multiversal conquerors. The massive destruction caused by this war lead the victor, known as He Who Remains, to found the Time Variance Authority to prevent anything of the kind happening again.
