Replicators(SG 1) in Star Trek

[User1652]

So again based off my Replicators in Star Wars let's say a Asgard ship has somehow made it into the Star Trek Universe and was infested with replicators. The ship is somewhere deep in the Beta Qudrant and the first ship that it attacks is a Klingon bird of Prey that happens to be on a deep space mission. The timeline for star trek is in the begining years of the 25th century Post voyager era. Could the Replicators take over the Star Trek Galaxy?

They could try, but there's a lot more in the way of superbeings, like the Organians, Thasisans, Q, Metrons and so on that would probably prevent a 100 percent takeover. Is it possible the Replicators could overwhelm the existing conventional powers, like the Federation, Cardassians, Klingons, Romulans, and so on? It's very possible, as the Replicators have a very high production rate and a very Borg-like adaptation capability. Against the Borg themselves, that's another issue, as they have very similar goals and abilities. Then there's the other non-omnipotent powers, such as the Voth, Species 8472, Cytherians, and so on that would probably not take too kindly to the Replicators, and have enough of a technological ability to do something about it. The Voth, for example, actually have what could be considered the only weaponized transporters in all the ST Milky Way Galaxy, and could potentially beam away an entire Replicator starship by scattering it into individual atoms.

if no Omnipoint beings did not interfere with the Replicators could the galactic powers be a threat?

[Mike DiCenso]

See the second part of my post. Most definitely. Species 8472, for example, had the Borg on the ropes until Voyager and her crew interfered. There is no reason that the S8472 would hold back in fighting an obvious infestation of Replicators, blowing up whole infected worlds, as they did when fighting the Borg. The Borg themselves could also potentially use their nanoprobes to infect the Replicator blocks and starships, if they can get creative enough. The Voth have their transporter which can beam around whole Voyager-sized starships with impunity.

On replicators vs Borg, whoever wins, everybody else loses, minus the intervention of some super beings.
It's so bad that the Borg drones have those sort of ready to blossom kits: they slams their tubules into some structures and Borg bigs start to grow. That and the ships' hull regen + very good materials would make for legions of top notch bugs.
Against 8472, assuming the Replicators jump to their realm (the Replicators on their own would not do that since they'd first go eat everything that's already present in the galaxy first), it's hard to tell. Soon enough, the weapons of the bioships started to lose their rapestomp factor the more Voyager's crew worked with the Borg to update all systems. Voy's crew helped the Borg do what they couldn't do: help their nanoprobes circumvent the defenses of the 8472 species' specimens.
Replicator nanites are considerably smaller and just as good at assimilation, but we've seldom seen the bugs attempt to take on biomatter and living beings until AoT, and it was rather crude.
The Voth are pretty much a non problem. Crude beaming tech the Tau'ri were given by the Asgards would already let old Prometheus beam an entire small skyscrapper into orbit. The Asgards themselves use two types of beaming tech, and the Replicators have clearly managed to block beaming technology. Heck, I can see the Voth beaming a cruiser inside one of those big ships, Replicators just adapting (because they're very similar techs anyway) and the Voth going "ow shit beam 'em out ! beam 'em ou--" and getting owned.
I don't know about the Cytherians.
The problem with typical warp-based tech is that it's capable of time travel. Say hello to the big can of worms. Surely the time cops of the 31st century would have to intervene in some fashion.

The first BoP should go done very quickly, but the bugs will attempt to capture it since it's new tech. The way things would go would be rather simple: shields go down, bugs gets beamed, the Klingons try to fend them off but their energy weapons prove worthless very quickly. Whether the Klingons think about blowing up their ship or not, the Replicators will already have gathered some intel, so that the next engagement against some Klingon ships will be easier. If the Klingons manage to send a message, they'll most likely not realize that they were at a severe disadvantage in terms of FTL speeds, so much that the nearest Klingon outpost or HQ will get a visit sooner than thought, if the bugs go for that kind of target. They would aim for a spot with known high technology, materials to use, but not too much of a force to defeat. Globally, as I'd already rate an Asgard ship above a Klingon BoP, added to the fact that the Replicators enhanced technology in ways that even baffled the Asgards, the Klingons might very well not properly assess the kind of ratio they need to win against an infested ship. The fact that those crafts all come with beaming tech among other things make bug deployment even more easier (the reason the Replicators couldn't use beaming in "Nemesis" was because Thor had made sabotaged the ship's beaming nodes and made the system for one-way trips inward).
In theory, the Klingons shall get overwhelmed. From there, the Replicators will have their way towards the whole of the UFP (which would probably send help at some point but most likely count some casualties, which would be enough for tech gathering to happen and then screw the UFP as well) and the Dominion (the Breen disabling pulse weapon will be a temporary annoyance at best).

The most annoying non-near-ROB faction is 8472, because we can't see how Replicators would do against them. 8472 bioships seemed to shrugg off Borg weapons - of course there's a no limits fallacy here, the most logical explanation being that those bioships simply were very powerful, which in conjunction with their defenses, prevented the Borg from defeating them, but then assimilation aside, getting 8472 ships down is a question of strength, and Replicators might have said strength. Those bioships aren't invulnerable: an impact at warp between a bioship and a damaged Borg cube, at a relative very moderate impact speed, destroyed the bioship. I don't recall any evidence that warp makes impacts particularly more violent between two ships flying at warp in a queue. Didn't even we see a ship graze two ships at warp and push them aside while shields coped with the impacts? We'd have to consider that the Borg fiddled with their cube and tried to make the section where the impact would take place more violent or effective.
There's the point that Replicators might still achieve something with the simple use of their dissociating acid-like spray.
Anyway, big ? on the 8472.
