Two of the vilest characters in the story. Naturally they required truly disturbing appearances.

Wang Ji, the adopted son of the leading eunuch Wang Fu, is a depraved monster of a man driven by an instinctive wish to inflict pain on people. Since his family's influence in the capital runs so deep he's practically above the law, over time he's become so sick-minded and unpredictable that even his own sadistic father can't stand him around the household. Only when he requires the means to overcome the Cao family and intimidate the prodigy, Cao Cao, does he summon the 'Mad Hound of Yongqiu' back to his side.

Hou Lan, known to many as the 'Enormous Spider Of The Palace', one of the most powerful eunuchs in the capital, is loathed and dreaded by all who know of him. While he hasn't served as long or as closely to the Emperor as his rivals, Cao Jie and Wang Fu, he has acquired arguably more influence than him by collecting not just the secrets of the Emperor and his kin but everyone, up to and including his fellow eunuchs, men whose dirty deeds could break them just as quickly as they made them. Since any threat to his life would compromise those secrets, the other eunuchs ensure no harm comes to Hou Lan and anything that would place him in danger or under suspicion is buried. This allows Hou Lan to act with impunity, forgoing the facades of sycophancy and courtesy the eunuchs are famous for as he does as he pleases to whomever crosses his path.

These two will give some people nightmares and are basically perfect pictures of what amoral people whose power, be it from wealth, connections or other sources, gives them the means to do whatever they want.
