Turns out, water treatment plants are a really, really easy place to contract the Roboenza virus, and so for the first time in years... Pump Man had to take a sick week. When he was hit with Roboenza, the clean freak Pump Man drastically changed - he no longer practiced safe hygiene! Oh, and, he may or may not have caused thousands of dollars of damages to the public sanitation infrastructure. Anyway, one of Pump Man's functions is the ability to remotely isolate denser droplets of water and waste for sustainable water management - it turns out, though, that when he was sick he was able to fully utilize those droplets as an insuperable barrier! Even with that, though, Pump Man's not much of a fighter, so Mega Man was able to get him to settle down pretty quick. Cured of Roboenza, Pump Man went back to the exciting world of wastewater treatment - as a neat freak, he can't ask for more. He makes sure to clean his office hourly to disinfect it from germs, and to keep things nice and lemon-scented. He's also the head of his local community volunteer clean-up group - they spend Tuesday and Thursday evenings cleaning up graffiti. He tried to get his clean-up pal Wave Man to come hang out, but it turns out businesses don't like when you try to wipe out graffiti with a harpoon. You live, you learn.
