Mjöllnir

Mjollnir
Mjollnir is the weapon used by Tanngrisnir Heracles the third god warrior to appear in Soul of Gold who fought Taurus Aldebaran in the asgardian colosseum.The weapon is a long green type of spear with a longer blade in one of the sides and a more pointy blade at the other.

Fate:
The weapon was abandoned by Heracles after he recieved the new Odin sapphire from Andreas.Heracles thought he didn't need his weapon after recieving such power but it proved to be a great mistake later on when he faced Aldebaran once again.It is unknown if the weapon was just abandoned or destroyed by Heracles,one episode prior to the Heracles and Aldebaran fight he is seen with the Mjollnir but it was likely an error and it is likely that the weapon will never return.
