Galda, known as the Dark Knight, is a warlord encountered in the "Jeffrey's Knighthood" episode. He commands an army of beast men and wears potent magical armor that enhances his combat abilities. Serving as a subordinate to the evil Baron Goldias, he relies on the Baron's sponsorship for his military campaigns.

During a confrontation with Lina Inverse, Naga the Serpent, and their client Jeffrey, Galda's armor initially withstands conventional attacks. His downfall comes when he insults Jeffrey, provoking Jeffrey's mother Josephine to intervene; she subdues him with a single strike of her mallet.

Following this defeat, Galda allies with Lina and Naga to confront Baron Goldias. In the ensuing battle, Galda grapples physically with his former patron. Amidst the struggle, Jeffrey attempts to charge Goldias but trips and falls. Goldias reacts in surprise, addressing Jeffrey by name and revealing himself as the boy's father. Josephine then arrives to attack Goldias, her estranged husband, resolving the family conflict. Galda departs alongside Lina and Naga, leaving the reunited family behind.
