The Oathkeeper

The Oathkeeper began life like many other Nepalese superheroes. His talents for manipulating time were discovered early and he was taken to a mountain hall to train and refine them. When he returned home at the age of 15, he found his village had been destroyed by a rampaging team of supervillains who had met, trained at, and betrayed a different training hall. Since that time, he has been on a mission to execute any supervillains who were trained in Nepal. He travels the Earth in saffron and crimson robes with an iron chain around his neck.
In recent years, a being who looks almost identical to the Oathkeeper has been murdering low- and medium-powered super-types more indiscriminately. The Oathkeeper has tried unsuccessfully to hunt this being, spoken of in whispers as the Oathbreaker. Since the Oathkeeper is such an accomplished hunter, some speculate that he only fails because the Oathkeeper and the Oathbreaker are one and the same.
