Few people have ever left their mark on one character quite the way Walter Simonson has. His work on The Mighty Thor swept the Norse God of Thunder to heights never before seen and rarely achieved in his wake. Spanning epic tales of heroism and treachery, love and war, Simonson's work is often considered the definitive Thor. From the majesty and mystery of fabled Asgard to the gritty streets of New York City, Thor was never the same. That is the mark of a true visionary. Thor's Celestial adventure continues as he discovers the true intent of the space faring beings that have set up shop on Earth. Guest starring, Ikaris, Ajak, and Sersi!
