The Silent Knight is a young handsome man named Brian Kent, living in sixth-century Great Britain.

While looking for one of Oswald's prize hawks in the Forest Perilous, Brian finds a trunk with a suit of silver armor, a sword, a red helmet, and shield.

Lady Celia who loved the Silent Knight suspected he was seemingly dull Brian, and even after being made to believe he could not be, was constantly troubled by similarities between the pair.

This, and an "inexplicable kinship" felt by Brian imply that he is an ancestor of Superman's adoptive father Jonathan Kent.

[5] In post-Rebirth continuity, the Silent Knight is reimagined as a former friend of Jason Blood who was corrupted after venturing into the Hollow Kingdom and became a conqueror.
