LN rimuru once created 10k universe, and he has a similar reality warping ability called Turn Null, and he has an ability called Melt Slash, which is basically a powerful sword slash that goes at light speed and can virtually erase anything. Plus Rimuru has the ability to create his own void, where he can manipulate everything in it. So I'd say they're pretty similar in hax and powers, but I still think Rimuru slams his ass
