I still feel like Pit having Soul Manipulation is to be worth looking at. To reiterate, it's revealed that Hades uses the souls of the deaths between the war of the Forces of Nature, Underworld Army, and Palutena's Army. But, it was also stated that it takes more than simply one soul to create a single monster. That can be assumed that these monsters are composed possibly dozens of souls, especially the bigger, and stronger ones. Pit regularly destroys these monsters without a sweat.
Also, don't forget the rest of the Resistances, bar from the Resistance to Physics Manipulation/Spatial Manipulation, but there were mixed views on which it was. But the other resistances seemed to be completely fine, as opposed to that singular one.
Which means these can be added too:
Resistance to Cold Manipulation, Resistance to Ice Manipulation, Resistance to Poison, Resistance to Durability Negation, Resistance to Soul Manipulation, Resistance to Paralysis, Resistance to Petrification, Resistance to Body Control, Resistance to Status Effect Enducement, Resistance to Lifeforce Manipulation, and Resistance to Transmutation.
Also, Dark Dragon, you missed a few other accepted hax. These should also be allowed:
Summoning, Size Manipulation, Explosion Manipulation, Resurrection, Body Control, Damage Reduction, and Danmaku.
These are also a result of some of Pit's powers and items.
As for what I think for the star feats, I'm sure they are, again, actual stars. The only reason that they look the way they do is that they are hindered by the resolution and hardware of the 3DS, stated by Sakurai himself. That's also precisely why he doesn't consider making a sequel, nor making a Switch port (sadly), because the graphics and resolution would have to be upgraded to match the Switch.
