What is the Hardest Boss in All of Terraria?

[@drunkenskunkproductionsdsp8094]

The Polarities are a pretty good contender for one of the hardest Terraria bosses. They base their positioning on your movement and constantly switch whether they're moving toward or away from you, which can be disorientating. They're fought at the same point as the Moon Lord.
