Let’s pour out a little oil for our robot homie.
Emet, the (not so) little robot that could. And he did—save Team Straw Hat, that is. But I don’t think anyone could guess he’d do it by unleashing Joy Boy’s haki. I wonder if Joy Boy specifically thought King Imu would be the one causing problems for his robotic friend in the future? Emet should be strong enough to take on just about any threat. Storing haki inside his buddy, Joy Boy probably thought Emet’s opponent would be a living being(s) too powerful or immune to standard weapons. Hmm… I’m really curious when Joy Boy and Emet had that conversation. My guess it’s near the end of their adventures together or even the last time they spoke.
Joy Boy’s haki (I presume) caused the Elders to retreat. Was it them specifically affected or was it King Imu? Are the Elders and King Imu linked in some way? Do the Elders even have devil fruits or does their power come directly from Imu? Hmm… That would help explain their immortality and invulnerability. So, if Imu goes down, the Five Elders go down with him. Interesting, if true.
