That still doesn't technically prove it. It could be that only with all those people and Alastor did they add up to 0.1% of Emily's power (in this theoretical, I'm not claiming any specific numbers here obviously).
Hey guys, I’m not here to vote , but I don’t think we can interpret it that way. In that situation, Emily was injured, so the amount of energy she released only formed a
bout 10% of the barrier at most (and Charlie, Husk, and Niffty were helping as well).
It’s worth noting that when the two ex-overlords joined in, the barrier started to become visibly clearer.
After that, six more overlords stepped in, expanding the barrier to cover
roughly 30% of the cannon. Then Alastor and Rosie joined, which caused the barrier to become a
complete 100% sphere and even lift upward. You can clearly see that Al and Ros’s power had a significant impact.
So I’d suggest scaling their power proportionally, something like:
(Char & Em) : (the 10 overlords) : (Ros & Al), or along those lines.
As for the context, if I remember correctly, that scene emphasized the unity of Hell’s citizens and showed that Hell does have a fair amount of power, which contradicts the old belief in HH Season 1 that Heaven was untouchable and immortal, and that Hell had no chance of winning or even surviving the exterminations.
To put it simply, the writer buffed the overlords of Hell (as representatives of Hell’s people) and nerfed Heaven and the Princess of Hell by injuring Emily and showing that Charlie still doesn’t fully know how to use her own power yet.
