The original version was created by Creig Flessel and first appeared in Adventure Comics #66 (September 1941).
During DC's "Silver Age" crossover event (not to be confused with the actual Silver Age of Comic Books), Dick Giordano and Geoff Johns created a new Seven Soldiers of Victory to fight an Injustice League that had possessed the bodies of the Justice League of America.
This version of the Seven Soldiers with Batgirl, Deadman, Metamorpho, Blackhawk, Adam Strange and Mento only served in one mission and the Shining Knight armor was destroyed.
Ystina is a reimagined character of the original created by Grant Morrison for the Seven Soldiers comic book.
[4] The Shining Knight and Victory made a brief appearance in Elseworlds' JLA: Another Nail when all time periods meld together.
