Most interesting part of the chapter by far.
The Seraphim retain some memories and abilities of the original.
Even if it's tiny like 20% of the original's capabilities, that's insane.
You get 20% Mihawk + Lunarian Speed or Defense, Pacifista Lasers and any further augmentations given to make them more effective in combat (Seraph Jinbe having a fruit that turns the surrounding into liquids for example).
And these guys all still have a lot of potential to grow.
Their durability is going to increase as they age based on this translation, their bodies will naturally get physically stronger/faster as well.
Seraphim are menaces. Vegapunk bred a generation of top tiers.
