Khârn the Betrayer 

Khârn is a favorite champion of Khorne, the Blood God from the Warhammer 40k Universe. He has an insatiable lust for blood and is known as the betrayer for his habit of messily dismembering allies nearby him when he runs out of enemies. In fact, the name Khârn is actually derived from the Arabic word for "betrayer". Despite all this, he is actually a pretty great guy.

I just watched Khârn the Betrayer dropkick a loyalist marine into that cluster of Thousand Sons; he exploded into confetti and viscera. He then gave me a high-five that shattered every bone in my arm. What a guy!

MY NIGGA YONGGUK ROBS AN ARMORED CAR TO SAVE YOUNGJAE AND THIS NIG SET HIM UP WITH THE POLICE
BETRAYED, MOTHERFUCKER.

If you were to look up the word 'betrayer' in the dictionary, you'd find Youngjae's face.
