Hammer Guarder was one of Glames's henchmen. His master decided to invade both Human and Dream world in order to save the inhabitants of the Dark world and prove his power.
Hammer Guarder commanded a squad of monsters to Tokyo city and was also sent to chase and capture Cham, whose father was killed by Glames himself. In a neglect, Cham was captured by him shortly after taking the Valis sword from Yuuko and finding her also. Yuuko saw this and went to rescue Cham searching for Hammer Guarder. They finally encountered once again and engaged in battle. Hammer Guarder was defeated by Yuuko who also freed Cham after his defeat.
The few dialogue he has in the game, shows Hammer Guarder to be arrogant and presumes about himself.
