Zeldris

is a demon who is a member of the Ten Commandments, a group of elite warriors of the Demon Clan handpicked by the Demon King himself. He was sealed away along with the rest of the clan in the Coffin of Eternal Darkness until he was set free by Hendrickson

Appearance
Zeldris' face greatly resembles Meliodas, except his Black Mark is on the left side of his face. He has spiky black hair and dull eyes, and wears a crimson pants suit and two gauntlets.

Personality
Zeldris is very calm and collective, seemingly not easy to anger. Like his brother, Meliodas, Zeldris appears to have good commanding and leadership skills, able to order his group like a captain and even list to him from time to time.

3,000 years ago
During the great war, Zeldris was tasked with executing a clan of vampires who attempted to overthrow the Demon King. However, instead of killing them, he sealed them away for Gelda's sake. Sometime in the past Zeldris clashed with his brother Meliodas. Along with the rest of the Demon Clan, Zeldris was sealed away by the Goddess Clan after losing the Ancient War against the Four Races (Human, Fairy, Giant and Goddess Clans).

Current arc
After Hendrickson managed to remove the seal, Zeldris, Estarossa and the rest of his fellow Demon Clan members appeared before the terrified former Great Holy Knight and Fraudrin in Dreyfus' body with Zeldris uttered Meliodas' name as if he knew him. After being informed by Fraudrin of the current events in Britannia, Zeldris suggested that they should head for Edinburgh Hill for recuperation of their severely drained magical powers due to the seal they're trapped in, which everyone agreed and left Zhuhur Valley by flight, leaving a terrified Hendrickson.

Arriving at Edinburgh Hill, Zeldris and his fellow Ten Commandments find a castle in ruins and concludes that it was Meliodas who caused the destruction of the castle as if there was a great battle fought there before noticing his brother Estarossa in a laid-back self, relaxing in the castle's ruins much to Zeldris' chagrin. Later on, the Commandments continued to rest and recover their magical power through the souls of humans they devoured and were shocked when they sensed Meliodas regain his full Demon powers at Istar.

Suddenly, Meliodas appeared out of nowhere through Merlin's teleportation and casually greeted the Ten Commandments who were alarmed of his sudden presence, except Estarossa who simply blinked in a laid-back manner and Galan who was determined to finish off where he started. Melodias battled and defeated Galan in less than ten seconds before warning Zeldris that the Seven Deadly Sins will defeat the Ten Commandments with everything they've got. In response, Zeldris and Fraudrin attempted to attack Meliodas from both sides, but he was teleported back to Istar. Galan was angered and humiliated by his defeat at the hands of the "Accursed Demon". Afterword, Zeldris suggest the Ten Commandments to split up and move across the land to regain their magic faster while calming Galan down after his lose against Meliodas. However, Zeldris remain behind as Estarossa refuse to move as he want to relax after being sealed for so long while Zeldris decided to look around.

Abilities/Equipment
Like all members of the Demon Clan, Zeldris utilizing the mysterious jet-black matter as shown forming wings for flight and as a member of the Ten Commandments, he may be exceptionally powerful. His aura is so powerful that made the normally calm Hendrickson sweat in fear of their mere presence.

Weapons
Zeldris wields a shortsword.

Meliodas
The relationship between the two, as it is now, is one of hostility. Zeldris seems to harbor nothing but anger towards his traitorous brother. It is unknown if they used to have a good brotherly relationship before the war 3,000 years ago, but he seems to be unforgiving of Meliodas's actions, whatever they may be.

Estarossa
Both of them are Commandments, though Zeldris gets annoyed with Estarossa laying around and ignoring his brother complaints most of the time, but show to care for one another as they are brothers.
