Sword of Omens
From Army of Gnomes Wiki
The Thundercats' most powerful weapon which is wielded by Lion-O. This sword can be extended to call upon the rest of the Thundercats if Lion-O is in danger. The sword's source of power, the Eye of Thundera, can be used as a spotlight to both call and empower the rest of the Thundercats team. This sword can only be wielded by the Pure of heart and cannot be used for evil. Despite this fact, Mumra the Ever Living can hold the sword for brief moments. This sword also grants its wielder the ability to see fellow comrades in danger, giving the ability of sight beyond sight. Can also be used against Plundarian Warmachines with it's ability to bestow power beyond power.
