Meliodas and Zeldris

Meliodas
-Meliodas is the leader of the Ten Commandments, Zeldris' younger brother and the eldest son of the Demon King. His clothing consists of a white vest with black stars permanently closed on the chest, with tight white pants and metal boots. His personality is especially known for its savagery and brutality in combat. So ruthless was he that even the Demon King considers him his successor, he is also someone serious, who gets upset easily and does not show any emotion or importance towards someone but inside he is someone nervous and shy. His appearance is like that of a 12 year old boy, he is 1.52cm tall but with great well-worked muscles.

Zeldris
-the representative of the Demon King, as well as his youngest son. Zeldris closely resembles Meliodas, having his black mark on the left side of his face, he has spiky black hair and black eyes, although without his demonic power activated, he has green eyes. His clothing consists of a full-body black suit (dark red in the anime) that leaves his chest exposed apart from having a high collar, he has two gauntlets and a sheath for his sword on the left side of his pants. Zeldris is very calm, collective and does not get angry at almost anything. Like his brother Meliodas, Zeldris has great leadership skills. Despite being a seemingly evil demon by nature, he seems to have a somewhat caring side, that despite his evil nature, Zeldris is still capable of feeling affection and love towards others. Zeldris; so he admired and feared his older brother at the same time. To strengthen himself, he trained for a long time, becoming the most skilled swordsman in his kingdom, in addition to having a great magical power comparable to that of his brother Meliodas.
