Okay so this pic is more like a modification I made of the last commission I got from tato on Furaffinity www.furaffinity.net/user/tato/, featuring the Road Rovers Colleen and Hunter (no blitz sorry guys). Anyway I came up with this idea after seeing various diapered rovers pics (mostly of blitz) and I thought suppose we also find out that colleen wears her diapers as well.
The modification is just correcting Hunter's legs so they show that his pants are down as well as Colleen's.

Though some people like to ship Blitz and Colleen, her and Hunter are the canon couple. Plus, the whole "flunked paper training" thing with Colleen from the episode "A Day In The Life"... It wouldn't be too much of a stretch for one to imagine Colleen actually being diapered, and by extension that Hunter would do something like wear diapers for her, when they're off-duty (in "The Dog That Knew Too Much", it's revealed that while they're on-duty, flirting is against the rules because it may demonize the others if they know for sure that Colleen and Hunter are a couple). So, lots of bonus points for a string of plausibility.
I think hunter is friendzoning Colleen, but he for her is nothing but a distraction from the thought of being attracted by Blitz, and that's the reason for why she is being such a bitch to him. And yeah, Blitz is kind of an asshole (but so is a certain decepticon a lot of girls love), but the main reason is he's frustrated by the fact not only Hunter but even Colleen herself is stronger than him, so, unlike Hunter, he can't be the protective male forward her.
