Timelines A, B: 1944
In the final years of World War II, Erik Lehnsherr—a Jewish boy imprisoned at Auschwitz—manifests the mutant ability to manipulate magnetic forces. Experimented on for his abilities by Nazi officer Klaus Schmidt, Erik eventually escapes captivity and spends nearly 20 years traveling the world to hunt surviving Nazis for their part in the Holocaust.
Meanwhile in Westchester County, New York, a young boy named Charles Xavier, who has manifested telepathic abilities, invites Raven Darkhölme—whose shapeshifting mutation also gave her scaled, dark blue skin—to stay with him in his home. (X-Men: First Class)
