Thor is the Norse god of thunder. A prominent deity, Thor was considered the strongest of the Aesir, and one of their greatest warriors. Thor was a protector of humanity, a slayer of giants, the son of the Allfather Odin and the wielder of the powerful Mjollnir, the fierce warhammer that could level mountains in a single blow. Thor was also destined to fight the Midgard serpent at the end of the world, and to die after he took nine steps away from the serpent’s twitching corpse. However, Thor also had two sons by a giantess who were named Modi and Magni that were destined to grow even stronger and greater than he was, and to survive him after Ragnarok. Each of the two gods represents something different in the Norse cosmology and in the value system of the Northern people of Scandinavia. However, each of the two gods has definitely inherited traits from their father.
Magni is the god that is the greatest in strength of all the gods. According to “Myths of the Norsemen” by Helen A. Guerber, when Magni was three days (or three years, the translation is off) he was able to easily fling the corpse of a massive giant off of his father. This giant was described as so weighty that all the gods together could do little more than budge him. Additionally, even though Thor required his gauntlets and belt of strength to wield the mighty hammer Mjolnir, Magni could lift and swing it unaided when he inherited the weapon from his father after Thor’s death.
Modi, like his brother, is a representation of strength. However whereas Magni is strength of a raw, physical sort Modi is the strength of bravery and courage. Modi is so brave that he knows no fear, and that fearlessness emboldens his own not inconsiderable raw power. The berserkers, warriors who could enter into a frenzy where they could shrug off wounds that should have killed them and deal astonishing blows in return, were often identified with Modi who was sometimes referred to as the god of battle rage, or of battle fury.
The worship of Modi and Magni wasn’t as common, since they were overshadowed by their popular patron. However, there has been mention of the two throughout legend and in obscure references throughout modern pop culture. For instance, in the World of Darkness game Werewolf, warriors of the Get of Fenris tribe were referred to as the Modi, showcasing their rage. Magni’s name may also have influenced the word magnificent, referring to Magni’s awe-inspiring power. These sons of Thor, despite surviving the end of the world, are still a lot more obscure than the earlier generations of gods, and this is true of many other survivors such as Odin’s sons Vidar and Narfi, who were also destined to survive the last battle and to ascend to places of power in the new world.
