Petyr masterfully created the illusion of harmlessness.

Petyr knows everyone’s weak spot and sets them up to destroy each other. The book doesn’t really tell us how Varys manipulates people, he’s taking more of a passive role. Varys was wrong about Joffery (who end up killing Eddard and messed up everything). He manipulates people, but always have some reserve. But Tyrion was betrayed by Shea, he has some serious father issue with Tywin. All three of them have extremely good judgement on character.

Petyr sees through people, and he never lets his emotions get in the way.

He has no family, no mysterious patron, he doesn’t even have that much money (sure he owns some shady establishments, but compared to Casterly Rock and a Pentos billionaire … it’s nothing).

Varys has his mysterious foreign patron, from whom he obviously receives intel, networking, and finance support. Tyrion has his family that he often uses as leverage when he doesn’t have his family to back him up, his life sucks. He has nothing to fall back on and he fights alone. Petyr has no background and no backing.Here’s my reason (Heavy spoiler alert! read at your own risk!): Her primary weakness as a ruler is her youth and relative inexperience however, she has a keen intellect and learns quickly from her mistakes. Her followers generally regard her with great respect and love, and she is often compared to her deceased brother Rhaegar, a similarly charismatic leader who was known for his skill, determination, scholarly mind, and strong sense of justice.

But he has taken it all as a man and continues to be one of the most flamboyant characters in the series. He has been thrown in dungeons, thoroughly humiliated, mentally scarred, cut in half, and almost always misunderstood. It took some time, but he got over it and fell in love again only to have it again taken from him. But Tyrion was made of tougher substance. This would have driven most men to insanity. When his father found out he had married Tysha, he had her raped by his guardsmen and finally by Tyrion himself to teach them a lesson. He has been called an “Imp” or “Half man” all of his life. I can’t even imagine how it would feel to see your siblings live the life you deserve, but instead you are condemned to your father’s hatred. Tolerance beyond comprehension: He has faced torture unknown to normal men and he was of noble blood. He seems to have the ability to get himself out of any insanely challenging situation he is put in, even if it is an impossible battle to win, like getting out of the sky cells of Eyrie. This has made him one tough nut to crack. His father holds him responsible for his mother’s death, and his sister greeted him with abuse instead of compassion. Overcome any adversity: He had a very troubled childhood and clearly has suffered ridicule and humiliation from every corner, even his own father.
