First appearing in The Shadow War of Hawkman, Thanagarian agent Fell Andar led a team to Earth to steal the Hawks' technology.
They married and Sharon gave birth to Ch'al Andar, translated to the terran name Charley.
When Charley was four years old, Thanagar called Andar to active duty by ordering him to infiltrate the Justice League as the second Hawkman.
It was Andar, not the Nth metal in Charley's uniform, that saved him from drowning at the hand of the Wildebeest Society during the Titans Hunt storyline.
[2] During the events of the Rann-Thanagar War, while trying to make up with his son and redeem himself for his own crimes, Andar died at Komand'r's hands.
