Dino Manelli was born in Italy and moved to America with his family, becoming a successful Hollywood movie star, featuring in acting and singing roles.
After the events at Pearl Harbor, Manelli changed his name and joined the U.S. armed forces (his original Italian name has never been revealed.
While at Able Company base, Manelli fell in with the First Attack Squad alongside fellow Rangers; Sgt. Nick Fury, Corporal Timothy "Dum-Dum" Dugan, Jonathan "Junior" Juniper, Robert "Reb" Ralston, Isadore "Izzy" Cohen and Gabriel Jones. It was this team's success that created the first recognized Ranger "Commandos". Shortly after this, the first attack squad, along with Manelli, became known as the "Howling Commandos". Manelli actively took part in the war behind enemy lines as a member of the Howling Commandos for almost the duration of World War II (circa 1944).
Later in the war, after Nick Fury fell victim to injury, Dino was reassigned to a new team known as "the Deadly Dozen" under the command of Dum-Dum Dugan, taking on both a Commando and front-line soldier role; taking part in historical battles including the Battle of the Bulge.
Towards the end of the war, Dino re-joined the Howling Commandos, although the circumstances are never fully explained.
Post-war, Manelli remained an active member of the Howling Commandos, fighting across the globe and from time to time teaming up with the likes of Colonel Fury and S.H.I.E.L.D. This would lead to appearances in upcoming wars, such as the Korean War and the Vietnam War.
In later appearances, Manelli has been seen to be wearing a S.H.I.E.L.D uniform, but again, the circumstances have never been explained.
Dino Manelli's character was loosely based on real-life crooner Dean Martin, which is often rumoured to be his original Italian name.
In his acting career, Dino was cast in roles including; Wyatt Earp, Dracula, and LA Dodger and as part of a comedy duo, alongside Jerry Larkin. At around the time of the Vietnam War, he also hosted his own Hollywood TV show known as "The Dino Minelli Show".
Growing tired of his acting career, Dino moved out to Las Vegas in pursuit of a singing career and can be seen singing alongside Josie and the Pussycats in Archie Meets the Punisher #1.
Although Manelli has no powers to speak of, his acting career and heritage provided him with adverse skills, that he used to his advantage in the theater of war. This included communications skills, from being able to convincingly "trick" the enemy with his acting and his voice, to being able converse fluently in English, Italian and German.
Complementing this, Manelli was competent at the art of disguise behind enemy lines, even passing himself off as a German Senior Officer.
As a combatant, Manelli was typically seen using a Machine Gun or Grenades, and has retained some of that ability in his later life.
