Sith!Obi-Wan put in the way that literally he is a clone of a Sith Lord of some kind(Nihilus? Revan? Bane even?) that Darth Plagueisis not spelling that shit correctly, anyway, made. It was a long time coming project he had in the back burner thsr the bane line had going for awhile but no one could get it right. Well, Plague did it but Obi-Wan is just an infant and didn’t have the Kamino style cloning where aging was done more rapidly. And Palps was planning to off Plague anyway soon. Palps inherits the Sith clone that is Obi-Wan, but finds the kid is really naturally drawn to the light, no experiments on the baby are changing it. And he doesn’t want to raise a baby so he gets the idea to ship Obi-Wan off to the Jedi temple with a weak bht present force bond. His idea is to have an Sith apprentice in maul who will act as his assassin, while Obi-Wan growing in the temple will get him insider info and a ‘apprentice’ who he doenst have to worry about training. However, it’s still Obi-Wan, even if he occasionally has overlapping memories from the person he’s cloned from csuse the Sith is haunting his ass and giving him ‘wisedom’. While the force bond between Palps and Obi-Wan is legit an estranged or deadbeat dead trying to get info out of their teenage son regardless of age over text
Outta like the last physical remnant of Darth Nihilus,
But like because Nihilus was pretty much going strong as no matter the physical matter has very little of the Sithly influence, took it with them as a ghost, and instead is much more grounded with an agressive craving for hot beverages
I imagine he’d be a bit of a spoiled brat of an apprentice compared to maul. But for how spoiled he is compared to maul his greatest failure is that Obi-wan is easily content. Very low ambition, his lack of greed is sickening
