Baked you are doing that thing again, after JUST saying you should rewatch it, where you claim something that is without question 100% proven false by the show.
When he ran out of Aura he made 4 of them and was able to hold them for 12 seconds which I know that doesnt seem like a long time but in combat that actually IS a long time as most real fights are counted in single digit seconds.
And they were able to pin Ilia as well as Hold a run away cart very obviously loaded with objects. You are just claiming low damage with ZERO evidence that backs that up and LOTS of evidence that shows they clearly have a sizable physical presence as ONE clone was able to tackle Ilia easily the other clones were just to keep her pinned.
As for it he can do them actually pretty quickly as evidence by him in the Blake short jumping up into the air summoning and then grabbing the earlier mentioned Cart or when he jumped in the air when facing the dragon and was able to QUICKLY summon the clones to move in air.
The pose is not this super long locking Sun in place move like you seem to think.
So if Sun THOUGHT there was a lot of swords coming and he made a lot of clones to act as a body shield then it would work and yes that type of clone use is something people have done before in other series like Naruto where they do in fact have a large cost to using it.
Beam canon Sun wouldnt create clones for he has seen that attack before back in vol 1 and its a pointed directional attack so he would run and use clones to get away from it.
There Emerald just needs to make Sun think the attack is splitting or doing something its not to force him into the beam she is making him NOT see.
We also need to take something into consideration with the whole Clone army draining his Aura. He took a hit from Ilia she headbutted him in the face to get him off her. Which that drains Aura.
Its also late at night and Sun has been running around all day before hand then the chase through the trees.
So it is heavily Likely Sun isnt at Full Aura for this fight though the exact amount is hard to say it could be as simple as he is at 90% or 60% we dont know outside of knowing by the headbutt at least he isnt at full and we can say chances are good due to timing and his activity before that most likely also drained his aura.
Since we STILL dont know how long it takes for Aura to recharge. Is there a longer charge when its broken vs not? Or is it the same no matter what?
