Black Knight

Black Knight was one of King Arthur's many Knights of the Round Table during the 6th century.

History
In the 6th century, the Black Knight was engaged in a jousting match when Timmy Jones, a kid from the 20th century suddenly appears right between him and the other jouster. Superboy arriving from the future swoops down and saves him, but in the process his sword is destroyed as it smashes onto Superboy's invincible body. The Black Knight is enraged and he challenges Superboy to a duel, but Superboy easily defeats him.
