Thus in this haunting alter-world the PeopleBusters hunt down any living being using slime-based weaponry and in an ironic twist they pursued the actual Ghostbusters after they got transported to the alternate universe, worse still the Ghostbusters' own weaponry did not work in the alien dimension and thus they were forced to switch roles as they fled from the ghostly "pest control".
The Peoplebusters, during their dealing with living Ray, living Peter, and living Egon, chased the Ghostbusters around Boo York looking to bust them, in much the same way Ghostbusters do to ghosts in their own universe. After all three Ghostbusters were put in the Flip Side version of the Containment Unit they found the same type of weather-like twister that brought them there. The Peoplebusters then came in to deal with them, but were stopped because the Ghostbusters' equipment worked in the Containment Unit's Earth-style environment, coating the Peoplebusters in their own slime weapon. The Ghostbusters then safely returned to their home dimension, along with all of the humans captured by the Peoplebusters.
In NOW comics Annual 1993, the Ghostbusters end up letting the Peoplebusters out into our world. As of the end of the story the Peoplebusters are at large in the human universe.
Flip-Egon is a skeleton with a tentacle replacing the rat-tail portion of his hair. There's even a mouth at the end of it.
Flip-Peter is a zombie who occasionally has trouble standing up.
Flip-Ray is a patchwork construct, styled after Frankenstein's monster . He even has a hand in place of one foot.
Flip-Janine is a zombie, but more skeletal-looking than Flip-Peter
Flip-Slimer isn't a ghost, but appears to still be an unnaturally occurring cephalapod-like entity. Possibly alive or para-natural.
There is no known Flip-counterpart to Winston.
The Peoplebusters' slime-throwing backpack is a large tank of green slime with eyeballs floating in it. The slime encases humans in an envelope of inescapable green slime, which acts in a similar manner to a trap. The slime apparently dissipates upon contact with a regular Earth-like environment, as the Ghostbusters are seen moving around unslimed after being dumped into one. Captured humans are thrown into a containment grid. However inside the grid is what's observed to be a pleasant earth-style environment. People have been entering the Flip-Side realm at least as far back as the 1920s, as evidenced by a female pilot wearing gear similar to Amelia Earhart's being seen in the Containment Unit. The Peoplebusters can also enter the Containment Unit at will, in order to enforce order within it should any humans they have captured try to escape. The Peoplebusters' symbol is like the one used by the Ghostbusters, with a depiction of Egon instead of the ghost. Also of note is that Egon's appearance to the citizens of Boo York is supposedly quite frightening, as Boo York barbers can make their customers' hair stand up by showing them a picture of Egon (to which Peter quips "And that's your GOOD side, too!").
One interesting conflict is the lack of Winston Zeddemore in a flip version. This might have something to do with the fact that Winston wasn't with the others when they went through the gateway. Other possibilities of why a Peoplebuster counterpart of Winston wasn't present could be that the Peoplebusters timeline works differently from the Ghostbusters timeline, and Winston's flip counterpart hadn't joined the team yet, or that Peoplebuster Winston was on vacation or out of town when Egon, Peter, and Ray entered the Flip Side world. Another curiosity is that the Peoplebusters Slimer is a giant red octopus-like organic creature. Since Slimer is a ghost in a world of living creatures, it isn't that big a stretch for Flip-Slimer to be a living creature (albeit a monstrous one) in a paranormal environment, even though it would make more sense if Flip-Slimer was human. Some fans have speculated that the red octopus creature was not really the Flip counterpart of Slimer, but possibly an odd delicacy in the flip dimension. Others claim that since Slimer is the only ghost that acts friendly and almost human, a natural flip would be an organic creature that acts scary and more paranormal. Another possibility is that Flip-Slimer is a para-natural entity, like the Basement Entity found in the Micawb's mansion. This would still make him alien in nature to the Peoplebusters' realm, since no living creature in the world of the living looks like what's found in the Peoplebusters' fridge.
Being alternate reality versions of the Ghostbusters they show similar traits to the mainstream team but are more bullying and mean-spirited, this is likely because the universe they inhabit is reversed so acts we consider cruel or dishonorable are actually "good" in their alien mindset.
They show dedication to their work, just like the Ghostbusters themselves but are far more aggressive in their pursuit of "people" - the residents of Boo York seem to consider them heroes, suggesting humans are disliked in that reality (much as ghosts are in the mainstream world).
The PeopleBusters are from a completely different universe from mainstream Ghostbusters and are thus unable to be classed properly, however they seem to rival the Ghostbusters themselves in terms of general technology but rely on slime (possibly a variant of mood slime) rather than the nuclear energy the Ghostbusters rely on.
They also do not use traps as the slime they fire from their weapons will easily capture living creatures and they can simply carry them off - an interesting note is that the Containment Unit they use sends humans to a seemingly pleasant dimension rather than an unpleasant one but this may well be due to the reverse morality of that world making what we perceive as "nice" to be "unpleasant" to them.
- They have the same iconic Ghostbuster logo as the mainstream team but instead of a ghost it has Egon's face (likely done as an in-joke).
- Despite being antagonists they are technically doing their jobs and the Ghostbusters at the time were intruding on their dimension (albeit accidentally).
- Since the comic book annual was never concluded properly, it is unknown what happened to the Peoplebusters. Prominent Ghostbusters fan Fritz Baugh wrote his own unofficial ending to the story where the Peoplebusters were trapped and put into the Containment Unit.
- The Collectors appear to be visually based on the Peoplebusters.
- On page 16 of Ghostbusters: Get Real Issue #2, on the right side are the Peoplebusters.
