Imu and his 20 good men/women against a three thousand year old (minimum since they did no just build a robot right out the gate so more than likely 4000+) Kingdom that had giant robots, world altering superweapons, and every non-human race united under them.
And Imu clutched that W regardless.
Anybody that at this stage is still in denial over how hard Imu will wreck the power scaling of the series I genuinely feel sorry for. Oda just keeps reiterating more and more on his "they don't build them like the used to" approach to world building.
Just gonna call it now, that 3000 year old robot? Was probably Nikas Emet/Franky and 3000 years ago was Nikas time.
