Loqi Tummelt is a minor antagonist in Final Fantasy XV. He was the main antagonist in Final Fantasy XV: Assassin's Festival, a free DLC event. He is a brigadier general for Niflheim and commands a unique magitek armor. He reports to High Commander Ravus Nox Fleuret.
- Brash, young commander in the empire's infantry, and pilot of the MA-X Cuirass. Despite his lack of field experience, Loqi proved his proficiency during combat simulations and quickly rose through the ranks. He took great pride in his imperial heritage and looks down upon all others born outside of Niflheim as "savages." While Loqi considers the decorated Lucian marshal Cor Leonis his self-professed rival, the marshal spares nary a thought for his imperial counterpart.
Loqi has blond hair and wears the same black and red imperial general's armor as Caligo Ulldor, albeit with the red and gold banner with his crest over the other shoulder, likely due to his left-handedness. The crest on his attire is also displayed on the flags magitek infantrymen carry across Lucis, and draped across occupied Lucian outposts.
As arrogant as he is skilled in his profession, Loqi takes pride in his imperial heritage, deeming anyone outside the empire a savage. He is brash and quick to engage enemies personally.
Loqi holds grudges against his enemies. He hates Cor Leonis, a Lucian marshal, whom he has encountered before and considers a rival. After losing to Prince Noctis, Loqi begins to begrudge him as well, and seeks to hunt him down. Loqi believes the empire is the highest force for good in the world, and holds Noctis personally responsible for the war between Niflheim and Lucis.
Loqi confronts Noctis Lucis Caelum and Cor Leonis when the two infiltrate the Norduscaen Blockade. Intent on killing Cor, the brigadier general battles them from inside a large suit of magitek armor. Loqi is defeated, and Noctis continues on his journey. Though his magitek armor was destroyed, several reserve units are kept in storage for Loqi to replace it.
Loqi heads to Lestallum during the Assassin's Festival to catch Noctis. Loqi and the magitek troopers he commands take over the town and imprison Holly Teulle, the head engineer of the EXINERIS power plant. The plan is to lure Noctis out, and they deploy the Wallbreaker Wave to cut Noctis from the power of kings, believing it would render him harmless. Cindy Aurum asks Noctis and his friends to free Holly, and they ambush Loqi and defeat his magitek armor yet again while Cindy dismantles the device that projects the Wallbreaker Wave.
At Formouth Garrison, Loqi teams up with Caligo Ulldor in an attempt to exact revenge on Noctis and his friends.
It is implied that Loqi accompanied Aranea Highwind in the relief effort in Tenebrae after the empire began to fall apart, as one of the unique magitek armors he pilots (the MA-X Cuirass) is among the troops that follow her.
Loqi, in his magitek armor, is fought as a boss in both the main game and in the Assassin's Festival DLC event. In the main game his MA is MA-X Cuirass. In the Assassin's Festival he pilots an MA Hoplomachus.
- Loqi bares a mild resemblance to Tekken fighter Lars Alexandersson both in likeness and armor design. In the reveal trailer for Noctis's addition to Tekken 7, Lars and Noctis have a non-canonical friendship.
