How big do you think the Kett are in Andromeda

From what little we know about the kett, I'd say they are likely a large Empire. We know that they're led by a Senate, itself led by twenty one "lineages", so basically the Roman Senate with the highest nobles families. We know that the Kett call Heleus Sector 1-19-NYKZ, implying control over possibly 18 other clusters at the time of their invasion in 2744 (an invasion that happened 80 years before Andromeda, so there more sectors could have been added). We also know that The Archon (whose essentially a Proconsul or Viceroy) has little oversight from the Senate, implying either an empire large enough to have centralization issues or a tech limitation causing major lags in responses from the homeworld, like Spain had with its American empire due to the Atlantic. Without further info we simply have no way of knowing if the Kett are Andromeda's Prothean Empire or merely a regional power.

One final thing for those who think that the Kett come off as too weak or underwhelming to be a major power: who says the forces in Heleus are their A or even B team? The Kett were fighting a decentralized, crippled civilization with little coordination: I wouldn't send my crack troops against such a minor threat. Plus the war's been going on for 80 years: likely the forces in Heleus were, until the rise of the Resistance, more of a garrison force investigating the remnant and exalting the Angara at leisure. No one could have predicted the arrival of an advanced civilization from another galaxy. Just something to consider.

They're nothing compared with real bad guys who created the Scourge.

You know I meant the part of the galaxy we'll be playing in, in the game.

And I've had about enough of your disingenuous assertions.

I think that we have only seen a small parts of the kett army, if the primus contacts the senate, things are not going to be pretty.

We shall probably meet other alien species in the sequel or dlc that are also fighting against the ketts.

They were supposed to send messages every 15 years with a progress report to the senate. So i think the Kett don't have QEC (Quantum Entanglement Communicators) technology, which may give the Milky Way species and the Angara some time.
