The intention with Vader is to immediately associate him with cybernetics and breathing apparatus from the moment we meet him, to reinforce what is seen in the OT.
Additionally, since I plan to have Vader fall to the dark during the second movie he’s not going to have a huge amount of time to flesh out the why of his fall. Fortunately clone madness comes prepackaged as an excuse, along with existential inferiority complexes regarding his status as a clone.
I didn’t feel that I’d have time to handle w"discover Anakin, take him as an apprentice, also deal with taking on Darth as a second apprentice". Luckily, Ben’s comments in ANH seem to paint Anakin as an equal rather than a student. And I realised dragging a retired Jedi out on a damn fool idealistic crusade works as well as dragging a wide-eyed kid, and with the advantage of skipping his training.
It’s a take on Anakin I don’t think I’ve seen before so I’m excited to work on it.
