Blood for the Baron!

Ok, I'll ask again, in more detail.
In G.I. Joe vs Transformers III: The Art of War, the BATs (BATs per se, not the TFs, who also were called BATs in the 1st mini) form a Gestalt (a giant combined robot like Bruticus, Devastator, Menasor, Piranacon, Predaking, etc). Which was the name of the combined robot?

wanna tell us?

The name was Cobratron.

Ok, since I (unintentionally) kept the game frozen, I'll make an easy one.
Name the charas that, without being repainted, got different names in the UK (it's easy, just see the Muticons).

Stalker
Snake Eyes
Rock N' Roll
Grunt AF Infantryman

That's right (except for / ; the figure IS repainted). I was expecting into the answer as well, but then I noted I had put the team logo rather than the toyline logo, so your answer is right, Ironblood. We'll expect your question.

Name the first main off-shoots of the Cobra Trooper

Not sure what you mean by that but in figure terms it would be the Stinger Driver?

That's one check yojoe archives or any early Marvel comics if you want to.

I thought the Stinger Driver (and SAS HUnter) were repants of the Cobra Officer?

How many are you after? Not sure if you are looking for the first specialised infantry units or characters like scarface...
