Enderman

He's three meters tall. He has a square head, long, thin, square arms, thin, square legs, and a square, elongated body. He's completely black, but his eyes glow purple. He has no mouth, but he can open his hidden, toothy, oil-like jaw. He's a vulgar monster who can't speak, only making sounds of space and a dying frog. If he's tall, then his lower half is also big. He can teleport without any portal, using only light force.
