My husband brought home a horrible sci fi film last night called UltraViolet and the bad guy was named DAXIS. Interestingly, UltraViolet was trying to save the bad guy's clone child named Six.
It's a 2006 anime/film hybrid, but I wonder if the story and name has been around a while in comic books and asian anime and might have some relationship to JMK picking the name Daxis for himself.
I believe the movie was made after a computer video game (but I could be wrong) - I looked up the movie info and it was cerified to play in Mayalsia. So he may have seen it. Also in the movie info they spell it Daxus.
