Nice Job Fixing It, Villain: In the final battle with Ozzy, he use the black chain holding the hypothalamus chromosome to try and choke him. But then Shane blinks, separating the two with the chain still around Ozzy's neck. His final attack failing thanks to Ozzy's morphing abilities seal the deal.
Laser-Guided Karma: Abolished Ozzy for having Frank throw up to get out an evil virus. Then at the end when he's been booted out of office, he presses a similar button and winds up flushing himself right out of Frank's own body.
My God, What Have I Done?: Doesn't say it but his reaction as the city of Frank burns down around him pretty much has this trope all over it.
Obstructive Bureaucrat: Let's see, he fired Osmosis and gets Drix out of Frank just for popping a pimple without permit (Which is like blowing up a building in the real world) and as mayor control's nearly all of Frank's actions, including his slovenly behavior. Said neglect needless to say, almost ends up killing the guy and every cell with him.
Vomit Indiscretion Shot: Double Subverted; we don't see it actually happen (although we hear him retching, the focus is on the horrified crowd at the science fair), but we do see a picture of him puking all over Shane's teacher.
Calling the Old Man Out: Blames Frank and his unhealthy habits for Maggie's untimely death, and calls him out for deciding to take her to a chicken wing Fan Convention instead of the hiking trip she was looking forward to.
Hollywood Pudgy: There are lines in the script that seem to imply that Shane is overweight. It seems likely that was the original intent and they never changed the script, because the actress they wound up casting is a tiny thing.
Missing Mom: Her mom died of an unspecified illness. Though it's implied she was as unhealthy as Frank has been throughout the movie.
