Echan

Time travelling sorcerer from beyond the end of time.

He has an artificial arm, with which he is able to channel a purple energy that functions similarly to ether blasts.

Speculation

He feels as if there is something off about the world he lives in, as if his experiences weren't the true, original version of events. The motivation behind his time travel is to find out the truth regarding this. Eventually his time controlling abilities become so powerful that he becomes the god of time, who resides outside of reality and turns out to have been the original cause for the divergent timelines.
