Ikaris is a member of the Eternals, a genetically superior offshoot race of humanity who possess abilities such as levitation and immortality. He is often seen as one of the most prominent Eternals, leading his race of people in many adventures.
Ikaris lived for hundreds of centuries on Earth as humanity evolved and developed. Throughout this time, Ikaris had many adventures battling the opposing genetic offshoot race from humans, the Deviants, who were created at the same time as and who have a never-ending hate for the Eternals. Ikaris also spent much of his life preparing for the return of the cosmic beings known as the Celestials, and he helped welcome them when they returned to Earth in the 20th century. Like almost all Eternals, Ikaris went mad and killed himself when he found out the dark secret of his race's purpose on Earth, but he was reborn later. Ikaris also helped fight the power-hungry alien known as Thanos on two occasions.
