The Organization XIII members outside of the Seasalt Trio and Saix actually did get development in Days! It was just cut from the movie version. For example:

• Luxord and Roxas gradually develop a sense of camaraderie. While Luxord isn’t the “fourth seasalt trio”, there was a sense of mutual respect.
• Roxas hates Demyx. Demyx always pushed his work off on Roxas. He apparently does this to every member of the Organization. The only reason Xemnas doesn’t kill him is that he’s great at recon.
• Xaldin is an incredibly angry and bitter individual. He sees all forms of emotion as a weakness, and wants to turn Beast into a Heartless not to help the Organization but to prove a point. He’s just that petty.
• Xigbar is shown to be just as much of a scheming monster as Xemnas and perhaps even more sadistic than Larxene. He enjoys playing mindgames with his subordinates.
• Xemnas is more bland than stale bread. His motivations change from cutscene to cutscene with Roxas even acknowledging that he has no idea what his deal is.
