Yondu in Earth-691 is depicted as a blue-skinned male with a large red fin protruding from the back of his head and his back; he is a spiritual warrior who can control his killing arrows via sound waves, most commonly by whistling. Yondu joined Vance Astro and other survivors of the Badoon attack on Earth's solar system in the 31st Century, who became known as the Guardians of the Galaxy. As part of the Guardians, Yondu traveled to present-day Earth and became an honorary member of the Avengers. The original Yondu never starred as a solo character in any Marvel Comic books, but was a core member of the team in the Guardians of the Galaxy comic that ran from 1990 to 1995.
