RE: Escaped Level 6 inmates
My first and foremost though regarding this is that it is a huge joke that we haven't heard a tiny thing about either of the escaped inmates.
I mean, sure, there shouldn't be that many that escaped BB's battle royale with the following recruiting session, but those that were able to escape this should be rather strong/skilled/experienced.
Additionaly to that did they have over 2 years to roam the sea and they should, in theory, get recognized by someone, shouldn't they? They may be ereased from history records, but I doubt that someone walked around and whiped everyones memory of these people clean and I also doubt that each and every of the escaped inmates thought that it would be nice to settle down and live a normal life after having faced the horror that was Impel Down. A few of them, maybe, but really each and everyone, sounds very fishy to me.
So yeah, I would've expected to see on of these by now or at least heard about one in a newspaper in-series or a few random stranges chatting in some panel background about one, but no, nothing.
I just hope that they allied themself with Kaidou or BM and we get to see at least on this way around.
1. Maybe some of them know a lot about the ancient weapons and history?
Would be interesting of this is the case.
Having an old giant, a person with a weird DF that grants them some kind of longevity or a person that is somehow affiliated woth the Kozuki Clan would be nice.
Though especially after the revelation of the Kozuki clan and their connection to the Poneglyphs do I doubt that another, similiar case, will pop up in the near future.
I can imagine that some of the heard rumors about AW and searched for them, but that is also how far I grant them to have gone.
So yeah, I doubt that we'll see an inmate with a conenction to either of these two points.
2. How strong are they? Close to Admiral-Level?
They should possess quite some strenght.
We had a glimpse of them in Marineford and that was after a state of years, maybe even decades, of imprisonment. They should have a huge potential and them being at least on VA level sounds reasonable. Some of them above or even far above them should also be possible.
I mean they were locked up down there and ereased from history for a reason.
3. What purpose do they have in the future? Are they gonna the existing balance between Marine/Shichibukai/Yonko/Revolutionaries/World Government?
That's basically everything I can imagine for them.
I don't wanna see one of them turning good guy and helping the SHs with some kind of information or so; I'd prefer to just see them wrecking havoc. I mean, them being a bit more than insane brutes would be cool, but I don't wanna see them turning good guy. Joining a Yonko, throwing of the balance, infusing fear that's what I would like them to do.
