So it looks like Ardyn has actual party member data. He has 17 moves whereas the other 3 has 13 (not including Noctis because has a ton more since he has access to multiple weapons). Ardyn has no weapon and reason why he has no weapon nor can't attack is because there is a 'new" category of weapon list for him. Which we don't have access to nor found any weapons for it. He also has a shield secondary called One_winged_angel. Can't be used and doesn't work (for now). It even has underscores which means that the devs left it there for future reasons maybe. He has a tech attack that requires 3 bars, however there is no mention on whom he pairs with that requires 3 tech bars. Or maybe he does it alone like Gladio's impulse? no one knows, he can't use it either since he has no weapon.
Ardyn also has a drive option for the Regalia with party members on auto, unfortunately nothing happens and goes right back to Ignis for auto. I assume the reason for that is because they never bothered to make an animation of Ardyn driving the regalia for the party members (he was never planned so it makes sense no?). He also only has one sleep/camping/inn rest scene, which is the one via the trailer car. This rest scene can pop up in the main story when you are about to meet Titan for the first time and he makes a pitstop to the gas station there.
Maybe he was suppose to be in 'temporarily' and then leave after similar to Aranea? nevertheless, he is labeled as a green flag, which means that he can obtain multiple sources of events to all trigger. What that means, is that he can be like Iris where he is suppose to have in car animation, in chocobo animation, freely edit gear and accessories etc. Basically the same thing as the main cast. Whereas Cor and Aranea are labeled as a blue flag not intended for those with locked gear. Course since we recently seen the poll by Square Enix for downloadable characters, we can be sure that Cor and Aranea will be labeled as a green flag to do everything Ignis/Gladio/Prompto can do. If you must know how I did it up there, I didn't. I had someone else do it for me via Playstation Dex forums.
