Hothbrodd appears in several related versions.

In the legends of the Ylfing Helgi Hundingsbane, he was the son of king Granmar of Södermanland, and he was killed by Helgi.

In Gesta Danorum, Saxo Grammaticus has merged the Ylfing Helgi Hundingsbane with the Danish skjöldung king Helgi. He has also made Hothbrodd a king of Sweden and the predecessor of Adils. This contradicts both the Norse sagas and Beowulf, and was probably an artistic liberty taken by Saxo or one of his sources to glorify the line of Danish kings.

In Hversu Noregr byggdist, Höddbrodd (Hǫdbroddr) was the son of a Höd. The name Höd is identical to that born by the slayer of the god Baldr in other tales. And while the Höd of the Hversu is said to be father of a son named Höddbrodd, in Saxo Grammaticus' Gesta Danorum (Book 3) Høtherus, the slayer of Balderus, is the son of Hothbrodus or Hothbroddus.)
