The First Undefeatable War was a top-secret, yet highly significant, war between the Undefeatables, along with their supporters, the Loyalist Army, and the villainous, chaotically disorganized PagUns. It took place over the course of the 18th century in Canada, but the specific dates are unknown due to the fact that the Undefeatables were involved, and some of their attacks were individually powerful enough to damage the flow of time itself.
