I strongly believe that George “borrowed” most of Ki-Adi Mundi’s story for Anakin. There are a lot of parallels between the two characters. I used to have them all memorized but it’s been years since I last read those comics. The biggest one that comes to mind at the moment is that Mundi is appointed to the Council before achieving the rank of Jedi Master. If someone else wants to chime in with other parallels I’d appreciate it.
As for why I think this. George is well known for reading and enjoying all of the Star Wars comics. He’s been sighted numerous times from the prequel era through to the Disney era of coming out of comic shops with the latest issues in hand. In Attack of the Clones he canonized Aayla Secura a comic character and later in Revenge of the Sith name drops her master. He would later go on to introduce said character in the Clone Wars television series.
It’s also not without precedence. Quite a few character designs and locations from the Droids animated series found their way throughout the Prequels.
