A little bit weaker than Shanks.
If I would have to order them : Shanks>Garling>Venus
But the difference is minimal, only Shanks might stand out a bit more.
Either way, whoever BurnScar is, he is valuable to Imu, which is, as you say, rather amazing...
We know Burn Scar is still a mystery and here we have a random guy taking spotlight here...
...quite sus if you ask me. He wasnt promoted to Elder and we didnt see him in the present.
So either dead or BurnScar himself, imo.
Whenever I point out Luffy's healing panchis you take a good hit of copium...
...is this a coincidence, Yonko-chin? Or you know they are weak and cant admit it?
