For some reason I'm only seeing few and fewer slime threads nowadays, so hopefully with the creation of this soon-to-be-closed thread, the supporters could be ressurected.
Infinite Speed Beelzebuth
When trying to save Gaia — Milim's pet dragon, Rimuru opted to devour the core exactly at the interval after Milim's attack destroyed the spiritual body but before that same attack reached and broke the core. In doing this, Rimuru used Beelzebuth which at that exact moment stated to be capable of ignoring time and space. It should be pretty clear with the given context that the statements lean towards its speed.
| “Okay, Chaos Dragon. We will set you free now,” I muttered, beginning the final step.
Timing was key.
The spiritual body of the Chaos Dragon had leaked out, and Milim’s magic had destroyed it, along with its astral body.
I witnessed all that, and before Milim crushed its core, I needed to execute ‘Devour Soul.’
Ignoring time and space, ‘Gluttonous King Beelzebuth’ was activated.
As long as I could see, it would finish the job faster than Milim’s magic.
And, my plan worked. I successfully obtained the Chaos Dragon’s broken core. |

Edit: Huh, turns out I was missing another feat. There was an instance as well where Beelzebuth is stated to ignore space-time, where in this case Rimuru used it to capture a teleporting bullet from killing an important person. Thanks

| —Eh!
To my shock, the bullet disappeared without a trace.
«Report. It’s a form of ‘Spatial Movement,’ called ‘Spatial Connection.’»
‘Spatial Connection’ apparently was a Skill that could connect two recognized points. The distance between the two points couldn’t be too far away, and the area of effect was very narrow, so it didn’t need much effort to perform.
But right now, I had no time to listen to explanations like that.
The red-haired woman was comprehending the space through ‘Magic Perception.’ The next second, the bullet reemerged next to Elric. She launched the Skill at the location with precision.
As a result—she completely ignored the two kilometers in between us as well as the outer walls. The assassination plan was about to succeed.
A small black hole appeared around fifty centimeters away from Elric’s head. And from it flew the lethal bullet travelling at over four hundred meters per second.
It was just as powerful as if it were shot nearby. There was no obstacle in its path, and the bullet was closing in on Elric.
Slowly, but surely. I could see it travelling.
Yet in this situation, there was nothing I could do. I didn’t have time to warn him, and even if I were to take action, I wouldn’t be fast enough to stop the bullet.
«…There is no problem. Activate Ultimate Skill ‘Gluttonous King Beelzebuth?’ YES/NO.»
Eh, will it seriously make it? That was just my own doubt, but I still listened to Raphael-san’s proposal.
And the next moment—woah, incredible.
Ignoring space-time, the bullet lay in my hand, motionless. |

So we have 2 times where Beelzebuth is depicted to be Rimuru's fastest attack where it can instantaneously reach its target faster than Rimuru can perceive/reach, and being able to ignore time and space in the process.
As if it not enough, the lesser version of Beelzebuth, Predator,
can instantly consume Infinite Prison which holds infinite-sized space. This is probably not enough on its own, but its serve as a good supporting feat. Long story short, Beelzebuth can ignore time and space, and capable of actually devouring infinite-sized space. This would also upgrades his range via Beelzebuth.
