So we have the Minks who can manipulate electricity, the Fishmen who can manipulate water, and King's "Winged" race that can manipulate Fire. My speculation that King might be from some sort of Dragon race might not be that far off.
Also, why aren't we talking about how much of a dick Hawkins is. As if Kid doesn't have it bad enough already with fighting Big Mom, now he's gotta worry about Killer's fight with Hawkins. The worst part is he doesn't even know it, so he's going to be in the middle of the fight, not even getting attacked, yet still taking damage and be life "Wtf is going on, she didn't even touch me."
