Frankly what the hell are the Elders and Imu thinking?
They already failed to get the SHs with all Five Elders and a buster call with one navy admiral and many vice admirals in Egghead...
Yet now they send Pranks and some random person alone?
Why is Oda insisting on making the WG look like fools? This shit is worse than the planning and thinking of Team Rocket in the Pokemon anime.
Normally, Imu would let the world descend to chaos just to nip this SH problem in the bud and keep the Void Century secrets safe.
Send a nuclear buster call with Akainu and all admirals and all seraphims and as mny vice and rear admirals as possible. Screw everything else, let the nations that are protected by the WG get toppled, the WG can get them back anyway with another great cleansing and 2nd Void Century... But no, let us make the villains fools.
