Controversial "Imu using a sword to kill Luffy isn't Hawk Eye upscale"

[BillSlipton]

Yeah, but he is much less susceptible to virtually everything else to which Garp would likely be susceptible. Of course he's also completely vulnerable to seawater but that's not really a weapon, just an unsuitable environment.

Sea water can be a weapon in the right hands. Dont limit the imagination.

And none of those things make your original claim true. Luffy has no more of susceptibility to swords than garp does.
