Well, going by the evidence that everyone of them (SH pirates) had grew in strenght from island to island, if he survive (witch is a given), after what he has experienced in the last 30 hours, not including Amazon Lily, you can safely bet that he will be at least two or three times stronger the before! Yay! (maybe I'm pushing it a bit too far, but seriously, he has gone trough a WHOLE lot, surviving the island of women, breking into ID, making it down to Level 6, escape from there with an army of prisoner, partecipated with a major role in one of the greatest conflict in history... he could really put everyone to shame if he treasure enough of what he has done lately, man

).
