Quasar (Wendell Elvis Vaughn) is a fictional superhero appearing in American comic books published by Marvel Comics. He is one of Marvel's cosmic heroes, a character whose adventures frequently take him into outer space or other dimensions. However, Quasar deviates from the archetype of the noble, dauntless alien set by such Silver Age cosmic heroes as the Silver Surfer, Adam Warlock and Captain Marvel (Mar-Vell) in that he is an everyman. He starred in an eponymous monthly ongoing series written by Mark Gruenwald that ran for sixty issues beginning in 1989 and has served as a member of The Avengers. Publication history The character first appeared as Marvel Boy in Captain America #217 (Jan. 1978). He continued to make guest appearances in Captain America, The Incredible Hulk, Marvel Two-in-One, and The Avengers. He was revamped as Quasar by Mark Gruenwald, and first appeared under this new name in The Incredible Hulk vol. 2 #234 (April 1979). Quasar received an eponymous series in October 1989, written by Mark Gruenwald and illustrated by Paul Ryan and Danny Bulanadi. The title crossed over with Infinity Gauntlet, Operation: Galactic Storm, and The Infinity War. Later, the New Universe's Star Brand was introduced into the Marvel Universe. Its presence precipitated into the "Starblast" storyline, which was intended to stir up interest in Quasar's solo series or a prospective cosmic team series starring Quasar, but it failed to do so. Quasar was cancelled at issue #60. He would appear sporadically over the next several years. The character appeared in the 1996 Star Masters miniseries (as well as Cosmic Powers Unlimited & Silver Surfer vol 3 #123) as part of a team of cosmic heroes with the Silver Surfer and Beta Ray Bill. He also appeared in the Avengers: Infinity miniseries, Maximum Security (2000), and Fantastic Four #521-524 (2006). Quasar appeared and died in the four-issue mini-series Annihilation: Nova (June-Sept. 2006). He appeared as a spirit in Annihilation: Conquest: Quasar #1-4 (Sept.-Dec. 2007), by writer Christos Gage and penciller Mike Lilly. An astral form of Quasar had a recurring role in Nova vol 4 beginning with issue #17, as the writers Dan Abnett and Andy Lanning (known collectively as DnA) thought he was too useful a character to stay dead: The character regained a physical form in the Realm of Kings one-shot (2009) and played a role in The Thanos Imperative (2010). Quasar assumed the leadership role
