Post a bored sadistic জীবন্ত character.

We all know the obvious answer. ;)

Our human-loving psychopath:
Mr. Orihara

If your bored means that the character feels bored often,
then Okita Sougo from Gintama

Alois Trancy

Uryuu Ryuunosuke from Fate/Zero

Man.. he maybe cheerful in this pic, but mind you, he's just another bored,psycho,serial killer that thinks GOD is an লেখক of people's lives which makes him a character with a role that kills children -_-.....

Hisoka from Hunter x Hunter.

Accelerator maybe ?

He may not be bored but he is sadistic. Mayuri Kurotsuchi from bleach.

Trafalgar Law "Surgeon of Death" from One Piece

me

Well, he's not in the জীবন্ত yet, but when he does appear in it, boy, I can't wait. He is Yoshikage Kira from Jojo's Bizarre Adventure: Diamond is Unbreakable

Here's Amaimon looking bored as usual.
