How about Prince/Lord of Time if you please?

A Prince of Time, Destroying Time, Destroying the Timeline, or Destroying through Time, they may be reeeeally bad at Time Loops you know. Destroying the Flow of Time itself may Time Stop, or perhaps like I implied with the Thief, skip time, making the Prince of Time another possible contender for Diavolo’s Classpect.

Also, the Lord of Time, I mean. That’s Caliborn’s powers, and I think the Canon does a good job at showcasing the deep control over the Timeline LE seems to have.
