Working a nine-to-five job as a wage slave sure sucks. Which means that when you discover a fragment of an ancient life-giving alien artifact, it's time to clock out for the last time and launch a career as a super-villain! No? Well, Slo-Mo seems to think so.
This dishy dame's timepiece has the power to slow down machines, even stop 'em cold. In their tracks. Company halt. It even works on those annoying Autobots!
Amusingly enough, she seems to have a mutual attraction with the speedster Nanosec.

Slo-Mo first appeared on the scene as a mysterious benefactor who helped out several of Detroit's B-List Villains, saving them from capture by the Autobots with an Allspark-empowered timepiece. Gathering these three 'also-rans' at her former place of employment she introduced herself. Formerly a production line worker, she one day discovered what would prove to be an AllSpark fragment mixed into the quartz crystals she fitted into clocks. When installed in a clock-like housing she found it slowed down all electronic and mechanical systems, from automobiles to automatons to Autobots. She realized this was a chance to make it big she set out on a career in crime, but had the sense to recognize she was an amateur at the game, and proposed that the gathered crooks could restyle themselves as a crime syndicate. She also revealed that it was her AllSpark-powered timepiece that had undone Nino Sexton's premature aging, and this favor seemed to kindle a potential relationship between the two.
The as yet unnamed syndicate's first bust quickly went south on them however when they became cornered not only by the Autobot Bumblebee (who was quickly defeated by Slo-Mo's timepiece) but also by the flesh-and-blood officers of the DPD. Fortunately, an anonymous caller on her watch-phone quickly offered them the services of a nearby Sports Utility Vehicle as a getaway car, complete with 4-wheel-drive, inbuilt weaponry, and comfortable seating for four (complete with a booster-seat for Professor Princess). Speeding away, she was nonetheless unimpressed by their patron's attempting to undermine her authority, and didn't feel indebted to him for just a truck. After finding out that it was a truck with a ridiculously large turret she was far more tractable. Now liking what the man was saying, her eyes lit up with dollar signs as their benefactor described the ultimate heist.
Unfortunately once all the items were gathered her sugar daddy mentioned one niggling detail: the final part of the device they were going to sell was the very source of her superpowers. The deal soured, forcing the unseen voice to reveal that he was their getaway car. Slo-Mo was a quick thinker, realizing she could blast him with her timepiece. Unfortunately the Decepticon was a quicker thinker, using first a handy-dandy forcefield, and subsequently an even handier, dandier tractor beam to steal the timepiece. Slo-Mo was out of luck. Gathering her similarly depowered cartel members, she teamed up with the little girl with the pigtails to haul the yellow Autobot to Sumdac Tower. It was all just a ploy to get her timepiece back though, and she double-crossed the white hats as soon as she was able. Sadly, she was unable to recognize the effects of her own timepiece on the getaway car, and thus was hauled away by the black and white.
