Eternia™ is not short on strong personalities. Some protect Castle Grayskull™. Some lurk in Snake Mountain. Some change faces, swing weapons, summon beasts, or command magic everyone would be wise to stand several steps away from.

Between the Sorceress watching over the secrets of Grayskull, Teela charging into danger without waiting for permission, and Man-E-Faces proving that one hero can make quite an entrance, the forces of good have more than muscle on their side. Unfortunately, Evil-Lyn™ has ambition enough for an army, Beast Man is never far from trouble, and Trap Jaw remains a walking reminder that bad ideas can be heavily armed.

Dimitry Burmak, Alex Horley-Orlandelli, Benjamin Marra, Stephen Andrade, Craig J Spearing, and Ed Repka bring the great clash of Eternia’s allies and enemies to life with heroic steel, villainous magic, savage strength, and all the theatrical force a world this dramatic requires.
