His legs got weak and he built robot-like machines out of metal to help him walk.
Because zeus threw him off mount olympus.
I believe that Hephaestus is the son of Zeus and Hera who was crippled so Hera threw him off Mount Olympus which probably did not help. It was Tantalus, not Hephaestus
Hephaestus was born from Hera and Zeus and had a birth defect so they threw him out of Mount Olympus and his fall caused his grotesque appearance.
Hephaestus is Zeus' son
In a myth, Hephaestus's father and mother (Hera and Zeus) were having a fight. When Hepaestus backed up Hera, Zeus grew furious and threw him down Mount Olympus, crippling him in the fall.
Not much, certainly not the ire of Hera or of Zeus, his mother and father both threw him from Olympus and Hephaestus was no less famous a Greek god.
Hephaestus was handicapped. It is said that when Zeus first saw his son and did not find him satisfactory, he threw him off his palace window and that is what crippled Hephaestus.
Hephaestus was born of Zeus and Hera (along with Ares and Hebe). When Hera layed eyes on Hephaestus, she was so horrified because of his ugliness that she threw him off Olympus, crippling him. Another version of the story says that Zeus threw Hephaestus off Olympus. After Hera saw what a good craftsmen Hephaestus was, she apologized and took him back. Later on, Hephaestus built a throne chair for Hera that had a trap in it. When she sat in it her arms and legs were shackled in and she was stuck! Hephaestus left her there for a while before freeing her (legend has that Zeus had to threaten or beg Hephaestus to release Hera).
Yes, Zeus is Hephaestus' father.
He got into the middle of an argument between Zeus and Hera so Zeus threw him off of Mount Olympus, injuring his leg.
Hephaestus was Zeus's son. Hephaestus is the son Zeus and Hera. Sometimes it is said that Hera alone gave birth to Hephaestus, without male fertilization.
Hephaestus is the son of Zeus; or if the child of Hera alone, Zeus is his uncle.
