My P4P Rankings
1. Jon Snow - After a short stint on the IR, he came back with a vengeance. He took on the great and undefeated Ramsay Bolton in the Battle of the Bastards and won via brutal GnP. King in the North, and King of the P4P list.
2. The Night King - Almost everyone is ducking him. The icy fucker even has giants in his army. Can he be beaten? Who will dare try?
3. The Hound - Yeah, he made a mistake by taking a fight on very short notice (hell, he was mid-shit when he took the fight), and was below 50% at the time, but he still gave Brienne everything she could handle even with her advantage of elite armor and sword. He retired for a bit, but then came out of retirement and showed that you don't fuck with his friends. Appears to be one of the very few heading towards the Night King.
4. Zombie Mountain - Had an extended stay on the IR, but returned better than ever. He's all about crushing skulls, ripping heads off, and making people piss themselves. Made Septa "Shame" Unella his bitch. Such a threat that the king banned trial by combat.
5. Arya - She had an extended training camp at the House of Blackzilians and Whitezilians where she racked up some impressive wins over Meryn Trant and fellow HoB&W prospect, the Waif. She returned to Westeros with vengeance and wiped out House Frey.
6. Brienne - Made her name off of facing people when they're at their lowest. I'm kind of surprised she didn't show up at Winterfell and kill Ramsay after he was beaten and imprisoned. Spends her time failing to protect people, being an unlikable brute of a woman, and training up-and-comer, Podrick Payne.
7. Grey Worm - Took out the Sons of the Harpy except for the few he left for Selmy. The man with no fear went on the IR for a bit, but came back and showed he's returned to form in the finale by quickly executing 2 of the rich masters.
8. Tormund - Veteran with many wins, most recently and notably defeating Smalljon Umber via neck bite and follow up strikes at the Battle of the Bastards.
9. Dario - The Ben Askren of Game of Thrones. We've never seen him lose but drops in the rankings due to a lack of competition. Dany (Dana) doesn't want him in Westeros (the UFC).
10. Bronn - Took a hit when he traveled to Dorne, and hasn't really had a chance to redeem himself yet. In need of the bad pussy?
