Whatever Happened to Jon Valor - The Black Pirate of 2 Worlds

Jon Valor was a British nobleman seeking to enforce Justine on the high seas. In order to secure his identity, he adopted the privateer alter ego of Black Pirate, using his athletic prowess and skill as a swordsman as a costumed crusader during the latter half of the 16 century. Eventually, he was captured by the Spanish Armada, and while in captivity wed local noblewoman Donna Bonita, which led to his being enlisted in Spain's service. 

Raising their son Justin, Jon trained the lad into becoming his sidekick. The pair had many adventures, little aware that they had identical counterparts with similar history in another Earth. 

On Earth-Two, Jon and Justin continues to work aids bu side, with Justin eventually replacing his different colored outfit for one matching his sire. This was no doubt to train to succeed him as the next Black Pirate. The pair were brought forward to 1985, where they helped Firebrand and other historical heroes defend Cape Canaveral from Ultra-Humanite and his forces during the Crisis on Infinite Earths.

On Earth-One, Justin appeared to have been lost at sea after he and his father battled a vessel filled with lost pirates. Five years later, while being sent to the Netherlands by the King of England to root out a new brand of pirates, Jon encountered his long lost son. Justin had been rescued by Puritans, and while suffering temporary amnesia was converted to their cause. He was behind the latest pirate sittings, seeking to obtain funds for his people’s cross-Atlantic journey. Assisting his son one last time, Black Pirate helped defeat the English fleet arriving on Dutch shores, and saw his son off as Justin and the Puritans sailed away to America.

Soon after this, Black Pirate and other historic heroes of Earth-One were pulled into 1978 by the Lord of Time. Pirate and his four allies battled the Justice League and Justice Society, before aiding them in saving all time from the Lord’s destructive Eternity Brain at the end of time. Following this, Jon returned to his native time and his waiting wife.

The adventures of the Black Pirates and the Justins (in Sensation and All-American Comics) seem to have mirrored one another up to the point where they diverged, when the one Justin left for America and the other carried on the family tradition. It seems that this Earth-Two Justin had a son who, in the 1800s, was named Jon after his great-great grandfather and became his generation’s Black Pirate (as chronicled in Action Comics).
