We see in this week’s episode that three viltrumites show up to take down Allen. This means they know where the coalition of planets homebase is located.
Why then, do they not just destroy their planet, especially since we have seen them being able to take over planets on their own. Won’t a dozen of them or so be more than enough to take down their biggest threat?
By the end of the episode it seems the leader of the coalition is the mole.
And considering the fact that he was already of old age when Allan was born and he is STILL the leader I guess he is a very old Viltrumite, especially since he looks very humanoid and has a mustache + some extra facial hair.
Probably he’s even the one where Allan got his power from (maybe he is even his father, technically speaking ?), why else would Allan have so similar powers ?
In case he is really a Viltrumite than it’s obvious that the coalition of planets is already part of the Viltrum empire. The people are just not aware of it.
So - why attacking a planet that’s part of their own empire ? It seems as long as they don’t actively rebel of fight, the Viltrumites don’t intervene.
Maybe the new members which got attacked TRIED to fight, so an intervention was needed?
