Generation 1 Series (sometimes G1 Series replaced the "Classic Series" label in later waves).

True to their word, the Universe toys are divided to various "series," with their on-package bios confirming the characters' presence in pre-existing continuities:

When Hasbro first announced the Universe toyline at BotCon 2007, they said that it would not have a unified story arc. Many similarly appeared in various Wings Universe material from Fun Publications. Some Universe toy designs appeared in the 2005 IDW continuity starting with All Hail Megatron, but those comics were not branded under Universe in any way. The Titan Transformers comic also used the Universe name and logo for some reason, despite all of its story content being set firmly in the live-action film series continuity (one of the few franchises not appearing under the Universe banner). Like the previous franchise, this line is intended to be something of a catch-all for toys that don't fit in the main line - in this case Transformers Animated. Transformers: Universe, begun in 2008, is the second Transformers franchise to use the name.
