Galliard family

The Galliard family (ガリアード家) is an Eldian family living in Liberio under the rule of Marley government. It is the family where Marcel and Porco Galliard hail from.

History
When they were children, Marcel and Porco joined the Marley military to become Warriors. They were both excellent Warrior cadets and were chosen to become the next hosts of the great Titans. Marcel was a candidate for the Jaw Titan and eventually got it, while Porco was a candidate for the Armored Titan but Reiner Braun obtained it rather than him. This was due to Marcel's intercession, who managed to give his brother a bad reputation as he did not want him to become a Titan and have his lifespan reduced.

In year 845, the Paradis Island Operation began and Marcel left Marley while Porco stayed behind. During the mission, Marcel was devoured by a mindless Titan.

Marley arc
Porco, in his Titan form, fights at the battle of Fort Slava. After Marley wins the war, Porco gets back to Liberio and sees his parents again.
