The merman zooms off to the other end of the beach, drone in tow. Tony wastes another minute hollering and gesticulating futilely, and then he gives a frustrated huff, shoves his yimo into his back pocket, and takes off sprinting down the beach.

Tony is certainly not a runner by inclination, but he does have a bootleg nanotech supersoldier serum running through his veins, so he can put on quite a bit of speed when the situation calls for it.

When he's in shouting range again, he makes another attempt at diplomatic resolution. "Dude, seriously, that's mine, bring it back." Don't make him come in there, merman guy. He doesn't want to get into a fistfight with fishman over a robot, but he will if he has to.
