Abigail is a heavily built man with a long face, and dark hair, who appears to be in his fourties.
Abigail has shown two distinct personalities throughout the series. The first was how he acted while under the control of Anthrasax; a sadistic megalomaniac. After being freed from Anthrasax's control, Abigail became very calm and stoic, but still somewhat over-the-top in his actions.
Abigail was a scientist at the end of the Old World, and one of the Ten Wise Men of Europa. His exact discipline was never revealed, but as one of the Twelve it is suggested he was working on the study of the spirit and spiritual matter such as Eternal Atoms.
After the destruction of the Old World, Abigail became a dark cleric, and traveled the world.
Shortly before the start of the series, Abigail broke one of the four seals holding Anthrasax, and became possessed by its spirit.
When Dark Schneider destroyed Abigail's body shortly before the two-year timeskip, it destroyed the essence of Anthrasax within him, leaving his soul free to rebuild his body. He hid himself in a technologically advanced exo-suit while his body was healing, and allied himself with Yoko's group as the Samurai Angus Yarn. He stayed silent for two years so that no one would recognize his voice, until he finally revealed himself during Dark Schneider's battle with Kall-Su at the floating Elven city of King Crimson. Yoko and the others were shocked that they never figured this out, considering Angus Yarn's face looked just like Abigail's.
