[DCU] How strong are actually the Endless compared to The Monitors&Perpetua/Darkseid&Highfather/Lucifer/Dr Manhattan? I mean outside their respective realms since inside they seem to be virtually invincible. Could they actually be killed for good? Are they unique across the whole multiverse?

We don't know the range of their power (even if we know that Death is the Death for all of DC characters) but they can be killed. If they are killed, another one appears with the same skillset and persona. They are ideas, they can't totally dissapear.

But i think Death and Dream are the strongest, Death for obvious reasons and Dream because he can use dreams to make everything he wants and control people subconscious (of course he can be killed but only if he let peoples do it). Dream probally can beat anyone he want in their sleep if they don't know he is here.
