This is speculation based on the new episodes that aired in Singapore. Spoilers are likely.

When Airachnid tries to take over command of the Decepticons, she claims that Megatron has abandoned them and proposes that they leave Earth. After she gains some support from the troops, she immediately gives the order to set a course for Regulon 4.

What do you think is at Regulon 4? Could it be a Decepticon colony? Or something else entirely?

 

More creatures to hunt?

 

I have no clue, but it looks like Lord Megatron has another insuboradnate aboard his ship.
(I can't spell tonight)

 

I swear this name was familiar ... until i realised that Kup mentioned it to the Dinobots in the Original Movie ...

Regulon Metalmongers?

Is that foreshadowing that Kup would make an appearance instead of the highly anticipated Jazz or Ironhide?

HMMMMMMMM!!!!!

"Me SG_Grimlock Loveeeeeeesssssssssssss references to old school Transformers."

 

My thought is that it's a Decepticon outpost. Airachnid may have been planning a refuel/repair as well as picking up more troops.

And perhaps put a note in the original post that this speculation is based on the Singapore-aired episodes. I've read the spoilers, but others may not have.

 

It is probably the closest Decepticon colony. We didn't get a lot to speculate on, it is probably just a Transformers reference for the longtime fans.

 

I think that what ever Airachnid does I support her. She's the only reason I still watch the show.

 

Whatever it is, it probably won't result in her permanately leaving Earth. She still has a score with Arcee and Jack.

 

Airachnid's Regulon 4 can be a Decepticon space station, warship, or planet.

According to Soundwave, Airachnid's Regulon 4 is not important since he didn't move from his post.

 

Maybe Regulon 4 is her old lab?
