He is voiced by Tomoaki Maeno in the Japanese version and by Clay Wheeler in the English version of the anime.
Invel is a bespectacled man of average height. Most of his long, blue hair is bunched up into a ponytail by a golden brace. The ponytail hangs past his right shoulder, reaching up to his chest. The rest of his hair is quite messy, with uneven bangs falling down the sides of his face and between his eyes. He has alert eyes with red irises. His attire is quite trim, befitting his strict personality. It comprises of a simple pair of dark dress pants and a white collared dress shirt, completely buttoned up with a blue tie hanging from the neck. Over this, he dons a trench coat with a white border. The color of its interior as well as its exterior matches that of his tie. Dark markings are diagonally branded from the left shoulder and sleeve and run down the front and the back of the coat. The coat has a high collar which is left unfolded. The cuffs are also quite large. As the coat cannot be closed down the front, Invel fastens it with a long belt, looping it twice around his waist and then holding it fast with a simple buckle. This leaves part of the front of his shirt exposed, allowing the tie to be tucked neatly into the coat. The belt itself has a pattern of diamonds running across it. His outfit is completed by a pair of dark shoes with contrasting light soles.
Invel is one of the four Spriggan 12 members to greet their emperor. He also appears in the meeting. During the Invasion he stays on Zeref's side and locks the army away so that Natsu and Zeref could fight. After their fight concluded he returns to stay on Zeref's side.
After Irene casted Universe One he uses Ice Lock to lock up Mavis and her unable to resist. He also appears in the big meeting of the Spriggan 12.
He later confronts Natsu's Team freezing everyone except Gray and he overwhelms Gray. Then he locks Gray and the de-frozen Juvia with Ice Lock and forces them to fight each other until they seemingly kill themselves.
Then he plans to meet Brandish, but is confronted by a very angry Gray who overwhelms him even when the Spriggan 12 mage uses his ice armor and defeats him. After his defeat Invel reveals E.N.D.'s true identity: Etherious Natsu Dragneel.
When Fiore channels their might to seal Acnologia, Invel is shown to be still lying on the ground.
A year later, Invel was imprisoned for trying to wage another war.
