Marcos Gildark (マーコス・ギルダーク) is the captain of the Royal Guard and Knight Commander. Debuting in Arc 3, Marcos' only appearance in the main story so far is during the Royal Selection Ceremony, where he played a proxy role between the Five Royal Selection Candidates and the Sage Council.
Marcus has a chiselled face that–rather befitting of his stern personality and earth-based abilities–is often compared to a boulder or a craggy cliff. He is a large man with an abundancy of muscles which are usually concealed underneath his armour. Thanks to his bulging muscles, his neck and shoulders are impossibly thick, in comparison to an average person's. His eyes are blue and his green-coloured close-cropped hair is cut into the shape of a square. Unlike most members of the Knights of Lugnica, Marcos wears a suit of plate armour with gold trimmings. Transfixed to his waist is a sword he uses in battle. Overall, his appearance exudes the martial spirit of a disciplined warrior.
Marcos is a stern and strict man who takes his position as the captain of the Royal Guard seriously. He is composed at all times, allowing him to calmly deal with emergencies. He is also surprisingly thoughtful and perceptive which has allowed him to look for his soldiers on and off the field.
Roughly 15 years before the events of the main story, Marcos held a strong grudge against the Royal Knights, despite being one of them. According to him, all he did was imprison poor and starving people. Jail should be a place where people's hearts change for better. The unfairness he was forced to participate in, resulted in Marcos creating the Brotherhood, which allowed him to give people from the slums hope and help them change their lives.
Marcos became the captain of the Royal Guard following his achievements in solving Galic Fabless's murder and its related incident.
Roughly a year before the start of the main story, Marcos was approached by Crusch who voiced her request to accept Ferris into the Royal Guard and make a knight out of him. Due to Ferris' unparalleled healing magic, he accepted him among the ranks of Royal Guards and employed him many times in the following year.
Not long after the collective deaths of the entire Royal Family, Marcos assigned Reinhard van Astrea, Julius Juukulius and Ferris to accompany the two Sage Council members Miklotov McMahon and Bordeaux Zellgef to the neighbouring Empire of Vollachia. Roughly a month after their return, he arranged a proxy fight between the Lugnican Sword Saint Reinhard van Astrea and the Vollachian First ranking Divine General Cecilus Segmunt.
About half a year later, Marcos played a proxy role during the Royal Selection Ceremony, due to his position as the captain of the Royal Guard.
Rock Armor: Referred to as his trump card, Marcos can create body armour using magic that covers his entire body. The armour is made of grey stones, increases his height to three meters, and makes him immune to things like poison gas.
Discerning Eye: By making his blue eyes glimmer slightly, Marcos can check for dangerous magic reactions and/or any equipment people may have.
Great Power: He's regarded as the second strongest fighter in the Dragon Kingdom of Lugnica, only falling behind Reinhard. He's said to be on par with Roswaal in terms of overall power.
- "He was called the strongest in the land, a battle-tested, old war dog. The man’s history and his skill with the sword left everyone in agreement that he was the second most powerful fighter in the kingdom. In other words, in terms of sheer strength, Marcus Gildark was one of the last people in the nation whose ire one would wish to arouse" Re:Zero EX Light Novel Volume 4, Royal Selection Prequel: Imperial Diplomacy of Bloodshed
