I was wondering, are/were there any really powerful beings in the WSU that were on the same level as characters like Spectre, Lucifer Morningstar,  The Presence or The Endless?

not really sure but there's

Void

Max Faraday

@Jonny_Anonymous: well the Void did reboot the Wildstorm Universe during the Captain Armageddon and Max has control of the Creation Equation that lets him control reality

but other than those two I'm not sure if they've ever shown anyone higher up...@Buckshot would know more than I do though

@Jonny_Anonymous: Given that the Scarlet Witch only produced her most amazing and infamous feat with the power of the Life Force (TM), which apparently dwarfed even the power of the Beyonder, comparing either The Void or Max Faraday to that version of Scarlet Witch would still be quite impressive. Aside from those two, the most powerful beings in the WSU that I'm aware of would probably be these guys, the Universals; though everything about them is vague and far more poetic than practical.

There are beings with multiversal-level power like Void and Jenny Quantum, but the WSU generally doesn't have a whole lot of abstract entities.
