No, Loki and Thor are not brothers in Greek mythology. They are actually figures from Norse mythology. Thor is the god of thunder, known for his strength and his mighty hammer, Mjölnir. Loki, on the other hand, is a trickster god who often causes trouble for the other gods. While they are not brothers, they are often depicted as companions or adversaries in various Norse myths. The confusion might arise because both Norse and Greek mythologies have rich pantheons of gods with complex relationships, but they belong to entirely different mythological traditions.
