Cyril Sheldrake, who inherited both the title of Earl and that of the Knight when his father was killed by his archenemy, Springheeled Jack. The second Knight rides a motorbike, and has a squadron of miniaturized Spitfires under his control. He is assisted by the third Squire, Beryl Hutchinson.

He joined the Ultra-Marine Corps and has accompanied several of them on a mission to save a crime-ridden miniature Earth. Years later, when the Ultramarines' base of Superbia was taken over, and the Ultramarines (including the Knight) became brainwashed by the combined efforts of Gorilla Grodd and the Sheeda, resulting in Grodd attempting to use the Ultramarines to take over the Earth, Beryl was the only one to escape from Grodd's grip and reached out to Batman, who led the efforts to liberate Superbia from Grodd's control. Following that incident, the Juesice League banished the Ultramarines, Beryl included, to the infant universe of Qwewq, believing that the Ultramarines' own recklessness was to blame for Grodd's rampage as Grodd himself. Later, after the Ultramarines had managed to sort out problems in the infant universe, the League allowed them to return to Earth.

After the events of Infinite Crisis, Batman went on a soul-searching journey around the world, seeking to rid himself of years' worth of anger and paranoia. As part of his efforts, the Dark Knight sought to reunite the Batmen of All Nations to which Sir Cyril and his father had belonged years earlier. Sir Cyril and Beryl were naturally two of the first to sign on. The group was captured, however, by an organization called the Black Glove, and subjected to a series of death-traps. Knight and Squire survived, and the incident improved the friendship between them and Batman and Robin.

During the Final Crisis, the Ultramarines aided the heroes against the forces of Darkseid, but the Superbia base fell after sabotage by the Justifiers.

Following the death of Batman, Knight and Squire have temporarily relocated to Gotham City to help quell increasing violence.
