That's actually false, Amaterasu has the ability to burn any element, so potential-wise it can burn any of Kaguya's dimensions considering it doesn't stop burning
Ok never though about it this way. I was simply focused on the point that Fire/Enton beats ice but yes theoretically Amaterasu can burn any of her dimensions because it is not a regular fire style but knowing that Kaguya can teleport that Amaterasu with her Amenominaka it isn't really effective. I'll give you credit that I overlooked the potential of Amaterasu.
She didn't fear Naruto the most, she took Sasuke to the other dimension because his powers can easily counter her organic reincarnation jutsu which she happened to use as soon as he was no longer by Naruto's side.
That's a situational type inference. They just happened to be at the Ice dimension where he had the upperhand. In the Lava Dimension she was a bit afraid by Naruto's incomptence. Granted that she doesn't have feelings you could tell by her body language who she feared lol. Also she didn't fear Sasuke necessairly, her main job was to split them up and attack them. His amaterasu could have been teleported to another area. It wasn't fear rather it was her sense to not be disturbed by both of them.
Actuallyit goes either way. You either take iut the small fry then take on the main treat otherwise you'll be too exhausted. Or take the strongest out first but then you'd use massive sums of energy then the rest which usually doesn't end well.
See, I don't see in the logic in taking out the weaker guy first. If I had to approach any solution, I would certainly not approach it from the viewpoint of trying to roast the inferior one. See, Kishi is very consistent when presenting things. In countless battles he has shown to get rid of the superior one.
Haku vs Sasuke or Naruto. He used his needles to immobilize Sasuke first because he thought that Sasuke was superior to Naruto.
Orochimaru vs Sasuke and Naruto. He used his oppurtunity to scare away Sasuke and persistently come after him thinking that Sasuke was the superior one.
Same deal with Kaguya tbh, she came after Naruto because of his dominance with his RSM. Sasuke was very inexperienced with the Rinnegan at the time so she didn't bothet digging into him.
Tbh Kaguya wasn't scared of anybody but the mysterious threat and being sealed again, Naruto was just really annoying they had to seperate them, if Kaguya really thought less pf Sasuke why not seperate naruto in the desert dimension, kill sasuke and destroy any possibility of ever being sealed and no it wasn't because of plot because if you replaced Naruto with Sasuke kishi would just draw Sasuke having more six paths abilities to compensate. But then, with Sasuke learning more paths, it makes his battle with Naruto mpre complicated.
Kishi wasn't displaying who was a bigger threat but giving the main characters spot light.
I don't think she was afraid of any of them as she posessed no emotions but sometimes her body language points out what she fears the most. How I think the spotlight thing worked is that Kishi gave Naruto time to shine against Kaguya and Sasuke against JJ Madara.
