So the two smartest people in the world? That typically won’t be found on battlefields either.
99% of the time it’ll defeat an entire enemy easily but 1% it may backfire. Those are pretty great odds
But this is a big deal fight though... The one time we’ve seen chemical warfare work for the beast pirates is the Zou invasion where they were attacking basically a primitive isolated society with a sneak attack and a spy leaking info
That’s a very good situation to dump chemical weapons wantonly
But this was them getting attacked with a very well coordinated attack by an enemy that is actually winning percentage wise according to CP-0
Queen was underestimating the enemy and how prepared the enemy was for him (he didn’t even know Chopper cured the Udon virus) so that’s his problem... He resorted to a tactic that works best when you actually know the enemies’ abilities
