Not sure about Kings of Hell since the ruler of hell (Azazel, then Lilith, then Crowley, then Abaddon, then Crowley again, then Asmodeus) is called king of hell.

Also, I guess I forgot the color of Abaddon's eyes, it's been ages since I saw Season 9 and Supernatural's not exactly easy to rewatch due to its extreme length.
