Who were heras sons but not zeuses of the greek gods?

Hera's sons who are not Zeus include Ares, the God of War, and Hephaestus, the god of fire and craftsmanship. Ares represents the chaotic and violent aspects of warfare, while Hephaestus is known for his skills in metalworking and creating beautiful artifacts for the gods. Both are significant figures in Greek mythology but are distinct from Zeus, who is often seen as the king of the gods.
