In the Universe Armada Mini-Cons thread there was a discussion about which continuity the Universe Armada Mini-Cons belong to. Hasbro has marketed them as being "Transformers Universe: Armada Series." So which is it? Do they belong to Universe continuity (i.e.: continuation from Beast Machines), Armadaverse continuity or Classics continuity (i.e. Timelines continuity) -- which is it?
I would actually say that they are part of the Armadaverse continuity.
Here's the thing...
1/ Classics itself isn't a single contained continuity. When people (myself included) refer to Classics continuity, we're really talking about the appearance of Classics in the Timelines continuity (Games of Deception) - which is an alternate continuation from G1 (and negating G2).
2/ Not all Classics characters belong to the Timelines continuity. e.g.: Classics Jetfire is part of the IDW mainline G1 continuity.
H'okay - so far we've seen that there are at least two different continuities where Classics Transformers belong to. But wait, there's more! In All Hail Megatron, aside from the canonical debut of the Masterpiece Seekers, we also see two "Classics 2.0" Universe toys in it as well! Namely Prowl and Sunstreaker.
Prowl
Sunstreaker
Neat, huh?
So basically, there is no "Classics/Universe" continuity, but rather Classics/Universe characters get slotted into different continuities such as IDW-G1, Timelines, All Hail Megatron - and yes, even Armada (in the case of the aforementioned Mini-Cons)... and there may be Classics/Universe characters appearing in other continuities in the future (who knows).
