He did not. However, he did have to go to the underworld and bring back Cerebus, the three headed dog guarding the underworld, but it was Zeus who brought back Persephone.

He finished the tasks even though Eurystheus thought he couldn't.
In one sense he was. He killed his wife, then was set 12 impossible tasks by Hera which he still managed to complete

Comes from Hercules. Hercules was a greek who killed his wife and children so had to take upon 12 tasks called the labours of hercules.
Hercules was an illegitimate son of Zeus so he was despised by Zeus' wife Hera. One day Hera made Hercules mad and in a rage he killed his wife and children. As a punishment for this Hercules was condemned to perform 12 labours for his rival Eurystheus.
That series of tasks was called the 12 labors of Hercules, and each one seemed impossible.
Eat 12 pies.
In a fit of madness, induced by Hera, Hercules slew his wife, Megara, and their three children. The 12 labors were his penance.
