Prince of Winterfell
A Clash of Kings
During his capture of Winterfell, Theon Greyjoy takes prisoner Bran and Rickon Stark and sits the throne within the castle's Great Hall. His sister Asha later mocks him for his inability to properly hold Winterfell, calling him Prince of Fools.
Prior to the battle at Winterfell, the outnumbered Theon tells Ser Rodrik Cassel's northern army that all who swear fealty to Balon Greyjoy as their king and to Theon as Prince of Winterfell will be confirmed in their rights. However, Theon is captured by Ramsay Snow during the sack of Winterfell.

Having been tortured by House Bolton, Theon emerges from the Dreadfort as "Reek", a ruined man. The Prince of Winterfell is who Theon’s psyche comes to recall when he thinks of the whole man he once was, before the dungeons of the Dreadfort, before Ramsay made him his new Reek. The Prince of Winterfell, was arrogant, handsome and cocksure – very different from who Theon is now. The Prince of Winterfell has become almost a third person to Theon, as he compares himself to him.
Theon travels to the siege of Moat Cailin under a peace banner to present the now-legitimized Ramsay Bolton's terms of rendition to the ironborn garrison guarding its three towers. Before he leaves Ramsay tells him,
You will pretend to be a prince, but we know the truth. You’re Reek. You’ll always be Reek, no matter how sweet you smell... You will be tempted to betray me. To run or fight or join our foes. No, quiet, I’ll not hear you deny it. A man would turn against me in your place, but we know what you are, don’t we? Betray me if you want, it makes no matter ... but count your fingers first and know the cost...
Later at Winterfell, Theon is chosen to ceremoniously present "Arya Stark", actually Jeyne Poole, in marriage to Ramsay, since he was the longtime ward of Lord Eddard Stark and it is widely believed that Arya's trueborn brothers are dead. When Theon gives away the feigned Arya to Ramsay he is made to play the part of the Prince of Winterfell once again.
- Theon to the people of Winterfell
I am the Prince of Winterfell! This is my seat, no man will drive me from it. No, nor woman either!
- Theon to his sister Asha Greyjoy
'I made myself the Prince of Winterfell', he thought, 'and from that came all of this.' He had thought that men would sing of him for a hundred years and tell tales of his daring. But if anyone spoke of him now it was as Theon Turncloak, and tale were told of his treachery.

'There will be no flaying here whilst I am Prince of Winterfell', Theon had responded, little dreaming how short his rule would prove.
