In the audiobook the narrator pronounces it “Lah-ah-uke”
Also I don’t think I would call it lazy because having Luke fight an insane clone of himself is pretty bold as it’s a pretty out there concept. I think him fighting another Dark Side user who is more machine than man would have been lazy.
It might have been a serviceable concept if it were given time to breathe in The Last Command, but as it is it’s pretty terrible. Most of Zahn’s writing on the Force makes it feel like a comic book superpower, rather than a spiritual one. Also, this is supposed to be a pics thread, so I’ll comment on this general crappiness:
Awkward composition? Check. Glowstick lightsabers? Check. Dopey Luuke? Check.
