Thankfully Pit can be resurrected too... With the help of Palutena.
I guess, but it still isn't confirmed that she is a Goddess, although she might have that potential. You know how attached I am to Palutena, so I try my best to make her look great. But in turn, Palutena provides different kinds of powers, some you know of (like the one she gave to Pit), and then there's exclusive ones she's used, like "Caging" and creating rain (shown via anime short). Who knows what other abilities she's been hiding from us?
The thing about Mewtwo is that well.. Mega Evolution forms are temporary, and different gods have different levels of power, so Arceus could be either a greater or lesser god, but we don't know that. Without Mega forms, Mewtwo will still be below Arceus. So unfortunately we can't compare the power of different gods extensively as we wanted to unless they actually had a duel.
For Sonic, FDL, as such with transformations, they're temporary in some sense: Sonic needs the emeralds and the form lasts as long as he has rings. FDL and Star Mario I don't know about. Mewtwo I explained.
For Palutena's case, I know she holds some of her power back as she's the peaceful type. Of course, we've seen a bit more of her power during that Chaos Kin incident, including throwing pieces of islands from Skyworld around in what looked like a giant whirlwind (I think) and creating a super powerful shield that only the Lightning Chariot could pierce through it (when going by the game only). Let's not forget the Glam Blaster during the Hewdraw bit, too. As I said, she's likely to hide even more power that we're not aware of. In other words, the thing about Gods is that they have power naturally without the need to transform like Sonic, and Link does. Ganon... I can't explain him. He's strong and I know it, gets resurrected sometimes.
All in all, Palutena is likely to be stronger than what some take her for, being a natural goddess, who although holds back due to being a peaceful one.
You know this conversation is interesting, but I feel that I have lost. D:
