Lagss (ラグス, Ragusu) is a loyal member of the Core Area Warriors and one of the antagonists of the Universal Conflict Saga, before she allies with Goku and Vegeta to defeat Majin Ozotto in the Demon Invader Saga.

Lagss is a humanoid woman with pale-blue skin and long pale turquoise hair tied in two ponytails with grey and gold hair bands and turquoise eyes. She wears a blue dress with a turquoise collar with gold trimmings, with matching golden trims on the side below her breasts and by her waist, which narrowly exposes the sides of her breasts. She also has unattached sleeves with the same gold trimmings as the others, while in the game, her sleeves are turquoise. She also has white boots with blue soles and matching golden trims, and dark blue-turquoise leggings. She has her grey armbands and purple gloves with gold trims.

Lagss is a calm, composed, mysterious and intelligent woman who maintains a cool and focused demeanor even in the heat of battle. Unlike some of the more chaotic or arrogant Core Area members, Lagss is disciplined and serves her role without question. Even when others falter, she stands by Hearts until the very end. She’s not overly chatty or expressive, preferring action over words. Her demeanor gives off an aura of intellect and planning, fitting her role as a kind of support figure and secret weapon. She speaks softly and deliberately, giving off a very controlled, tactical presence.

In her brief appearance, Lagss exhibits a ruthless nature, after wearing out Ultra Instinct Sign Goku, she mercilessly attacks the exhausted Saiyan with her glass shards.

She's extremely loyal to Hearts, as she obeyed his command to go assist Cumber in Universe 3 (albeit with some reluctance). When Oren questioned Hearts' plan while they were still in the Core Area, Lagss threatened Oren with her Glass Bullet - stating that Hearts' ambition was her reason for living. Her devotion to Hearts was further shown when she prevented Zamasu from betraying him and shielded him and gave him the completed Universe Seed when he was at disadvantage against Jiren.

Lagss is a smart and individual as she chooses to attack and neutralize her foes without giving them the chance to counterattack or recover and was able to foresee Zamasu's betrayal.

Lagss was taken to the Prison Planet and into the Core Area, allying up with the Core Area Warriors to aid Hearts in his task to overthrow the two Zenos as his most loyal ally.

Lagss along with the other members of the Core Area Warriors make an appearance after the chains surrounding the Prison Planet have broken and the planet is on the verge of destruction. After Fused Zamasu retrieves Cumber's unconscious body, Lagss and the others teleport away.
