Magni and Modi

In Norse mythology, Móði (anglicized Módi or Modi) and Magni are the sons of Thor.Their names mean "Angry" and "Strong" respectively and Rudolf Simek underlines that, along with Thor's daughter Þrúðr ("Strength"), they embody their father's features.Móði and Magni's filiation with Thor is proved by the kennings "Móði's father" (faðir Móða, in Hymiskviða, 34) and "Magni's father" (faðir Magna, in Þórsdrápa and Hárbarðsljóð, 53). Snorri Sturluson confirms it (Gylfaginning, 53, Skáldskaparmál, 4). According to the Skáldskaparmál (17) Magni is the son of Thor and the giantess Járnsaxa. There is no mention of Móði's mother.

[Norse] Magni and Modi, the sons of Thor, did not have many worshippers, as was common for sons and daughters of the major gods and goddesses. They did have a few, though, for the following reasons:Magni was considered the god of might, or strength, and was believed to be the only being in the Norse universe stronger than his father. His worshippers praised great strength and feats thereof. Magni was supposedly the only one besides Thor able to lift Mjollnir. Modi was the god of battle wrath. His worshippers were the archetypal berserks, some relying on drugs of various kinds to enhance their wrath and stifle fear. It is believed that some of his followers also worshipped Sif for her skill in battle.
