Serpenters

Serpenters (サーペンターズ) is a villain duo comprised of twin brothers Ena (エナ) and Dio (ディオ). They work for Flect Turn in My Hero Academia: World Heroes' Mission.

Appearance
The Serpenters are men of average build and fair skin with bowl-cut indigo hair, yellow reptilian eyes with dark purple markings surrounding them, and a set of large fangs.

Each of them wear a simple red and white tunic with gray, presumably snake skin, boots.

When boosted by Trigger, they become more vicious and snake-like. Markings appear on their faces, their hair flares up becoming spiky, their mouths stretch to their ears and their teeth grow sharp

Quirk
Sword Kill (ソード・キル): Both brothers have a Quirk that allows them to manifest from their arms and shoulders. When boosted by Trigger, they are able to create six at a time, one from each arm and four from their upper back.

Trivia

 * The Serpenters are referred to as the Twin Villains (双子ヴィラン).
