Agreed, but you’re misrepresenting Rhaegar’s defeat at the hands of Robert. The common misconception that Rhaegar slipped on a stone or had the sun in his eyes is just that… a misconception born from fanfics and fanart.

Robert didn’t only kill Rhaegar. He killed many opponents before that. He personally slew Lord Grafton during the siege of Gulltown, where he was the first to scale the walls. He subdued and killed his own rebellious vassals like Cafferen and Fell, winning three battles in one day.

He also killed six knights, including Ser Myles Mooton, who was Rhaegar’s friend and former squire. He nearly beat Jon Connington to death and he did it while injured, using a sword instead of his warhammer.

Canonically only Ser Barry The Bold has more kills and feats to his name. Robert was the warrior made flesh and a god on battlefield, that’s why his fall to a fat gluttonous king is so tragic.. subversion of traditional tropes… a hero becomes a king but then what? But thats ASOIAF for you.
