One piece: Strange Alliance 

It was originally planned to create a second team after the last hack http://www.romhacking.net/hacks/4655/ But, unfortunately, the main characters sprites did not fit in concept or size, so I had to abandon the idea of ??Side-Kick Team. 
The characters in this hack turned out to be strong enough, and if you want a challenge, put 5 or less lives.


Characters replaced by Trafalgar Law, Boa Hancock, Chopper and Nefertari Vivi.
All characters are fast and agile.
The voices also match their characters.
Weapons removed from some enemies.
All bosses except JET have increased HP.
Neutral Air Attack is now Air to Air. Works great for juggling an opponent in a corner or while playing in Co-op, but can miss when attacking a ground target.

This hack is based on the hack Dha Lau Hoo (https://www.romhacking.net/hacks/4592/). Only thanks Dha Lau Hoo can you do this: https://youtu.be/xyiXscCuyOY
