Iolaus was depressed by his failure to save a woman from falling to her death, and he told Hercules to find another partner. Fortune, the goddess of luck, was behind it all. Feeling bad for Iolaus, she tried to make amends by wiping his memory of the tradegy. Unfortunately, the meddlesome Fortune accidentally erased his entire memory, including Hercules. Iolaus went to work for the troublemaker Zeno and wound up fighting Hercules until the son of Zeus convinced his friend he had the heart of a hero -- not a killer. Then Hercules summoned Fortune, who restored Iolaus' memory.

As Alcmene's health failed, Hercules recalled the time years ago when the Parthans invaded Caylan territory. Young Hercules, Jason and Iolaus joined King Eteocles and fought bravely to repel the invaders, but the King was killed. Many more died before Hercules and Jason were able to make an offer of peace, asking King Stavros to share the disputed land with the Caylans. Stavros was impressed by their bravery and agreed ending the conflict. Back in the present , Alcmene passed away and was buried by hercules and his friends. Suddenly his father, Zeus, confronted an angry Hercules.

Bronagh, leader of the Celts on the island of Eire, told Hercules he was their ""Chosen One"" -- chosen to lead the Celts to freedom. But the gods of Eire didn't like the Celts worshipping Druids, so they sent Morrigan, a demigod assasin, to destroy the Druids. However, when she killed the Druid guardian of justice, she unwittingly took his place. Hercules, who finally stopped blaming himself for Iolaus' death, defeated Morrigan in battle, but the Druids explained that if she died, the spirit of justice would die with her. They disappeared, leaving Hercules to care for Morrigan.

Hercules and Iolaus answered Vlad's call for help to defend his kingdom against vampires. Arriving in Dacia, they were joined by Galen, whose sister Nadia had gone to Vlad's castle and never returned. Soon they discovered the horrifying truth: Vlad was a vampire, and Nadia had long since joined the undead. Nadia managed to turn both Galen and Iolaus into vampires. In a clever move to save his friends, Hercules ate hemlock and gave his tainted blood to the vampires. Thus weakened, Vlad was no match for Hercules. Upon Vlad's death, the others returned to normal.
