I HAD to figure out a way to justify buying this figure and fitting him into the mythos somehow, this is how I did it. LOL....
Once a highly decorated soldier in the Eternian Palace Guard, Officer Larr was ambitious and intelligent. Spending his days defending King Randor and his kingdom from evil doers, and his evenings studying anatomy and pathology, he had hoped to make a name for himself and escape the peasant upbringing he had left behind when he joined the Eternian military.
Unfortunatley, Officer Larr's temper and resentfulness of those in power was difficult to control. He spoke freely with a sharp tongue and fought brutally, beating enemies even when they had surrendered. King Randor told Officer Larr that he had to change his brutal ways or be discharged from the Eternian guard and sent back to the countryside.
In a rage, Officer Larr threw his helmet and weapons to Randor's feet and quit. Little did he know that Skeletor had a spy in the Eternian guard that brought this information back to him. Upon hearing of the brutal guard of Randor's, Skeletor saw an opportunity and seized it. Inviting Officer Larr to Snake Mountain, and offering Officer Larr a chance to put his brutality to good use. Working for Skeletor himself.
Officer Larr took Skeletor up on his offer and flourished under Skeletor's tutelage, specializing in torturing prisoners. Officer Larr's favorite method of torture was to pull and drill into teeth. Nicknamed by the other henchman as Mo-Larr. Everyone from Beast Man to Mer Man fear stepping out of line under Skeletor, because they know he'll send them to Mo-Larr. Where there is no mercy.
