This only means that Esdeath got stronger during the storm, which only places Esdeath's AP higher than it already is.
I would like you to find the scan that displays where it shows Tatsumi did not want to fight Esdeath. I thought it was discussed that Esdeath was deliberately prolonging her fight against Tatsumi, and Esdeath was actually holding back in that fight (Chapter 69 and Chapter 70 of AgK).
If you are proposing that Tyrant be upgraded, keep in mind that Esdeath needs to be upgraded to for casually brushing aside Tyrant like absolutely nothing. As such, according to your tiers, I propose these stats.
Tatsumi
- Attack Potency: At least City level, likely Mountain level
- Key: Tyrant
- I guess it logically makes sense that Tyrant would have gotten stronger as his previous forms followed this pattern upon each evolution (Form 4 > Form 3 > Form 2 > Form 1)
- Tyrant, as you described, is an ultra-class danger beast, and thus should be comparable in strength to this guy. I would suggest that you find the manga version of this picture, however, as the mountains were drawn bigger.
- "Likely" and "possibly" could be interchanged here as we are not exactly sure how much Tyrant is stronger compared to its previous form.
Esdeath
- It seems that after absorbing the Ice Cavalry, Esdeath released that Ice Storm Commander in Chief.
- You have noted that Esdeath has gotten stronger after she absorbed back her ice cavalry and created that storm, she was able to use time stop without wearing out, correct? I have provided the scans below.
- I only saw Esdeath stop time once in the recent chapter. Show me scans where Esdeath stopped time multiple times.
- Esdeath uses Mahpadma to freeze time
- Tyrant charges in against Esdeath
- Esdeath slices
- Tyrant is cast aside
Also, in chapter 54, Esdeath used Mahapadma during a battle, and was shown to still be able to fight just fine after she finished using it.
Note that she was still capable of fighting just fine during her battle against Magatama Susanoo, after she was shown to use Mahpadma the first time. This leads me to wonder if Esdeath being worn out after using Mahpadma is just a bluff on Esdeath's part.
Even if the AgK wiki states that she was worn out, actual feats contradict it, no?
I will wait for more input from the other staff members, as well as re-read AgK again, but this is what I have in mind. However, I would like everyone's input in this, especially those who have read Akame Ga Kill.
