Sera was a young woman from Corinth who befriended Alcmene. She offered the use of her uncle's gardens for Alcmene's wedding to Jason and the couple accepted. Sera was a spy for Hera working with Patronius and the Blue Priest to kill Hercules and Jason at the wedding. At the last minute, Deric recognized Sera as having been a spy of Hera's at the Slaughter of Biblos. He warned Hercules just as the giant sea serpent, Perfidia, attacked the wedding party. During the brawl at the party, Sera tries to stab a person with her dagger. Alcmene catches Sera in the act and punches her so hard that she is sent flying into the wedding cake, knocking her out cold.
