Universe has subsections.

- Classics
- Armada series
- 25th Anniversary
- Mics

Unfortunately as was predicted, this system was bound to cause confusion not only with the consumers but also with Hasbro as the differences between lines have been grayed and are no longer clear such as Classics with 25th anniversary.

Henkei in Japan however has kept things simpler but still a bit on the weird. Why put G1 characters mixed up with Beast Wars and now Micron Legend? I am hoping that the little comic stories that come with the toys explain this in a better form than Megatron drinking some bad Energon and becoming Galvatron.
