The Hybrid:

The Hybrid has multiple different things he can do after spawning:
1: He can act like the Man from the Fog and watch you from the distance, and if looked at, will either chase you or disappear.

2: He can stalk the player slowly by following them at a moderate distance away from the player and, when looked at, will keep watching the player or cower and disappear.
3: He can once again stalk the player by following them, but this time from afar, and if seen, will disappear or chase the player.
4: He can move towards the player when they can't see the Hybrid and when he gets close enough or is looked at, he will either disappear or chase the player.
5: He will watch you from a distance, sort of acting like the Man from the Fog, but if you look at him, he will teleport near you, and if looked at while near the player, will either disappear or chase the player.

The Hybrid has a higher chance of disappearing when looked at than chasing the player.

If the Hybrid isn't interacted with for long enough, he will either disappear, become angry and chase the player nearest to him, or change his "AI" to do one of the other things on the list.

If the Hybrid encounters an entity stronger than himself, he will deal his full amount of damage instead of dealing only a quarter of his actual damage like he does with the player.

The Hybrid can find you above ground and underground.

When killed, the Hybrid will drop pieces of himself that you can craft into powerful items.

The Hybrid can grab you by random if he hits you and can insta-kill you if you do not have a shield prepared or put you back down if he doesn't feel it is time for you to die yet.

When near the Hybrid your Fear will rapidly increase.
