When he attempts to spawn, there are 2 things that could happen.
Either he successfully spawns and triggers a spawn sound, or trigger the-

"Spawn Fail Mechanic"

This event has a 50% chance (configurable) of happening when he attempts to spawn.
He will not spawn, but trigger something similar to the Cave Dwellers "cavenoise".
This event will shortly attempt to spawn him again, and will keep repeating until
he successfully spawns and triggers the spawn noise.

After spawning, he will stalk the player silently with no warning other than his glowing symbols.
But when he successfully stalks and gets close enough (configurable), he transforms into the-

Aggressive/Monster Variant:

After transforming, there are 2 things that could happen.
Either he gives chase and starts attacking, or trigger a jumpscare.
the jumpscare has a 50% chance (configurable) of happening,
it also despawns him before he can give chase
and will shortly attempt to spawn him again.

If he gives chase, he has 4 simple features:
Climb walls/pillars
Break pillar platforms
Swim through water and lava
Open doors

It's a short list, but more will be added in the future along with new variants.

 Cave/Hybrid Variant:

He spawns every 1-3 nights (configurable).
His appearance is a hybrid of the Monster and Passive variants,
having a hook as his left arm and the rest is the passive variant.
He will fly slightly slower than you but has the edge as he will
incinerate/instantly break blocks with a 1 second cooldown.
He has no spawn sound or warning, the only sound cue
is when you hear him tunneling to your position.
He instantly disappears in contact with the sky.

Bloody Sign:

It spawns every 2-3.5 days (configurable).
It will appear at random spots on the surface, reading in japanese:
"I always watch".
The text is carved in blood, and the sign is slightly larger than a normal one.

Bed Bloody Sign:

It has a 10% chance to appear beside you when sleeping.
It has the same appearance as its other variant.

meaning he spawns next night.

simultaneously have Blindness and Darkness.
