Black Clover high tiers in General all have FTL combat feats. There was one fight between a High Tier BC Character (Yami) and a top tier (Patri), where it was explicitly shown that said top tier was using light speed attacks but he was too slow for the high tier, so the top tier starts increasing the speed of his attacks and that was when he actually started pressuring the high tier in terms of speed.
Then later, a top top tier (Julius) showed that the exact same character who was significantly faster than light (Patri) was like a child to his speed, and was massively restraining his own power and still almost defeating Patri multiple times.
Mereoleona, especially her current version, is a Black Clover top-top tier, or a mid top tier at worst if we downplay her. A character who can use Copy Magic (Rhya) started using one of Patri’s FTL Light attacks on her, and she laughed maniacly as she incinerated said attack.
OT: even if it’s all four of them at once, Mereoleona will incinerate the Yonko without them posing much of a threat to her. The moment that a massively less-powerful Mereoleona incinerated a giant water-dragon that was specifically made to counter her after she was incinerating every other form of magic that was being used on her, was when Tabata solidified Mereoleona as a character who isn’t going to take shit from any OP character.
And this was well before Mereoleona attained her current level of power which involves her literally “becoming Mana” (<-wtf) with her Hellfire Incarnate form. In addition to her treating Light Magic and Dark Magic respectively like a complete joke, she can also bathe in Magma (RIP) without any issues, has Mana Zone mastery which means she can turn the entire area around her into her own mana attacks, and overall she’s just going to raze everybody in OP. I would not at all be surprised if she could incinerate Akainu.
She incinerates Kaido and Big Mom with ease, they stand 0 chance at reacting to her or withstanding her fire. Teach’s Yami fruit may be tricky but Mereoleona, before her Hellfire Incarnate, was incinerating Dark Magic like it was a meme, so she probably just incinerates Teach very quickly as well. And Shanks we honestly have no idea but the fact that he is close to the other Yonko in power means he’ll likely be turned to ash very quickly.
Mereoleona is just way too much for the OP verse in power.
