Null is a player-like entity and one of the parts of xXram2dieXx's soul. He is the only known Soul, and one of two entities that can talk to the player.
His intentions are currently not clear, but according to himself, he wants freedom.
At the time of his death, Null was 14 years old, and after becoming an entity, he ceased to age both physically and mentally, remaining 14 years old for an indefinite amount of time
Null is a humanoid entity that possesses the same model as the player, with a homogeneous pitch-black skin.
Null will join the game at the first midnight, which is 18000 ticks (or 15 minutes in real-world time) after the world is created. After that, he will always appear online in the player list and can start appearing in the player's world as an entity — usually indicated by an eerie sound when he appears and the err.null error message when the player attempts to sleep in his presence.
Null will chase the player and play nulljumpscareloud.ogg and nullchase.ogg. During this, the player's camera will be locked on him, and he will be surrounded by
null particles, while the player is taking minuscule ambient damage.
While Null is chasing the player, he can break blocks and places Mossy Cobblestone on water, also changing the time of day to day or night with a 1% chance each tick.
Getting directly hit by Null will play nullkillsplayer.ogg and disconnect the player with a “null” error message.
When Null appears in this behaviour, the player's Reputation decreases.
22.5 seconds after spawning, one of the following will happen:
Null will teleport in front of the player, play theendisnear.ogg, and spam in the chat dark red messages:
HERE I AM
VOIDNULLSILUETTANOMALY (obfuscated)
Shortly after, he will kill the player and crash the game if crashes are not disabled in the Client Config.

Null, named MobIsmissingID, will spawn floating in the sky, observing the player. When he spawns in this behaviour, nullsad.ogg will begin playing.

He can only appear at night in this behaviour, disappearing during the day.
Null will appear in the player's base and stand in place.
If he appears 20 blocks of the player, each of the following will happen:
If the player gets within 7.5 blocks of Null, one of the following will happen:
He will disappear 4 minutes and 10 seconds after spawning.
Null will begin rapidly closing distance with the player, teleporting short distances towards them. During this nullishereloop.ogg (50% slower) will play, and white text lines will rapidly flash in the middle of the player's screen.

Coming into contact with Null will result in the player being banned from the world if banning is not disabled in the Common Config.
He will disappear 25 seconds after spawning.
Null will appear somewhere underground, wearing a full set of iron armour and carrying an iron pickaxe. His spawn will be accompanied by an eerie noise. Upon spotting the player, he will begin to mine and bridge towards them, intending to attack them.
Getting hit by Null will deal 6 damage. Hitting Null will cause him to disappear and play oneofus.ogg.
He will disappear 1 minute after spawning.
One of the following will happen:
Null, named [], will appear with a white health bar that appears at the top of the player's screen. Otherwise, his behaviour is identical to Null Is Here.

Null will appear on the ground, accompanied by an eerie noise. He will stand in place, always facing the player and watching them.
When the player gets within 4 blocks of him, one of the following 10 things will randomly happen with equal probability:
null particles.
eye particles.
null particles and send the player to Null Torture.
null particles and send the player to Day B.
null particles and teleport the player to their base.
null particles and teleport the player to their base.Trying to hit Null with an arrow will anger him, prompting him to Chase the player.
He can only appear at night in this behaviour, disappearing during the day.
Reputation is a measure of how good the player's standing with Null is.
The player, when creating a new world, has NORMAL reputation. The exception to this is WORLD2, where the player already has BAD reputation. Reputation value does not transfer to other saves and is separate for each world.

You can check your reputation using the command /tbs reputation
The only requirement is that Null has already joined the game.
The following interactions are capable of taking place, and are arranged in a table. Expand the table at your own risk, as it contains heavy spoilers.
