Except Loras Tyrell is a bamf in the books and the biggest pussy on the show. They ruined his character. He is literally the worst part of the show.
"Tyrion Lannister thinks Loras is beautiful and already a legend, and that half the girls in the Seven Kingdoms want to bed him and all the boys want to be him"
Loras defeated Ser Jaime Lannister in the tourney on Prince Joffrey's name day
Renly makes Loras the head of his Rainbow Guard, a fancifully ostentatious version of the traditional Kingsguard.
During his march, Renly holds a great melee at Bitterbridge of 116 knights; wielding a longaxe, Loras is one of the final two combatants, losing to Brienne of Tarth
After his failed parley with his elder brother Stannis at Storm's End, Renly appoints Loras to lead the vanguard in the coming battle, choosing him over Randyll Tarly, Guyard Morrigen, and many other candidates. After Renly's assassination, Loras goes berserk, killing Emmon Cuy and Robar Royce, the two Rainbow Guard in charge of protecting Renly that morning.
Loras joins the Kingsguard at his father's behest (though Littlefinger orchestrates this),[15] to protect his sister Margaery when she becomes the queen.
After departing his father?s funeral procession, Jaime trots through the castle gates and sees a dozen knights riding at a quintain in the outer yard. He stops to watch for a while he notes that Ser Loras rides superbly, and handles a lance as if he were born holding one. He observes that Loras puts the point just where he means to put it, and seems to have the balance of a cat.
After the invasion of the Reach via the Shield Islands by the ironmen, Cersei uses Loras's recklessness to manipulate him into attempting to quickly end the siege of Dragonstone, hoping that he will endanger himself in the process to free up Paxter Redwyne's fleet to defend the Reach. Loras departs the city amid throngs of admiring onlookers, mostly women.[20]
Aurane Waters later tells Cersei that Loras has taken Dragonstone. After Stannis's castellan, Rolland Storm, declined Loras's offer of single combat, Loras led the assault on the castle. The reported victory is said to have been needlessly bloodthirsty and true to Cersei's hopes, it is reported that Loras was horribly injured by quarrels, maces, and boiling oil in the battle.
Have you seen Mace Tyrell?s boy? The Knight of Flowers, they call him. Now there?s a son any man would be proud to own to. Last tourney, he dumped the Kingslayer on his golden rump, you ought to have seen the look on Cersei?s face. I laughed till my sides hurt.[24] ?? Robert Baratheon to Eddard Stark
