In Greek mythology, Heracles (also known as Hercules) was aided by his nephew, Iolaus, in his second labor against the Lernaean Hydra. Iolaus played a crucial role in defeating the multi-headed serpent-like monster. After Heracles cut off each head of the Hydra, Iolaus cauterized the decapitated stumps with fire to prevent them from regrowing. This collaboration between Heracles and Iolaus helped overcome one of the challenges of the second labor.
