Bring him to a digital, or technological plane of existence, where I can easily destroy him. I win.

Make a barrier that infinitely divides time so attacks can't hit me, put a timeloop on my stamina so it basically never drains, be a huge piece shit to dimentio by taking him to the timeline where he and I are romantically involved with one another, then hit him with hollow purple but time-based (maybe a ball of time reversal energy and fast forward energy mashed together to basically fuck him up)
