The Being That Can't Perish (Chara)

"You are all going to die sooner or later. Either way, you'll fall right into my hands."

- TBTCP (Chara)

The stats aren't clear...
There are no stats to chara. They are unknown.

Appearance.
Chara mostly looks the same, but they are completely black and have red eyes. (They're also genderless.)

Their mouth seems to be tied up, but they somehow can still speak.

Most of the time, two or more "hands" float beside them, but they mostly look like weird black clouds.

Personality
Chara is your average "Ay, I am going to kill you and it's an unfair fight" kind of person.

Basically, they want everyone dead, especially monsters.

Backstory
They are a manifestation of a dead body and hate and agony still remaining in the soul the body once had.

Their mother and father died both in a fight. Chara didn't expect it to happen.

After their sadness lead to suicide, hate and agony start controlling the body, erasing almost everything in their way.

Present Day.
They are held in Alphys' (and [??????]'s lab for experimentation).

Their "soul" isn't stable.

In the tank, you could see single hate parts flying around in the water, like Chara was just... melting.

Hands.
The hands float besides them and are capable of destroying iron.

Invincibillity (can be bypassed)
They can survive EVERYTHING, unless their manifested soul gets taken away. Then they "die".

K n i f e.
Their knife is like an amalgamation of stuff... sharp stuff, like nails, blades, cleavers etc.

Fun Facts.

 * 1) Chara hit Sans once, which he survived, but then got thrown into the outerverse (not literally, I mean, they got completely fought out) by Sans, and Toriel.
 * 2) They still like chocolate, especially milk chocolate.
 * 3) They are unaware of the Multiverse, but are still talking like they do.
