This new origin is part of the G1 timeline laid down by the Ultimate Guide, which is apparently being taken as the "official" G1 timeline for future projects that require it. This means there is only one Unicron who travels from universe to universe across all the assorted "Transformers" continuities. This interpretation of the character is evidenced by the parallel universe-spanning "Transformers: Universe" toyline and convention-exclusive comic books — in which the singular Unicron captured Transformers from various alternate realities and pitted them against each other, feeding off the energies released — and the "Transformers: Cybertron" comic strip in the Transformers Collectors' Club fan magazine, which depicts Unicron's actions in the various realities in chronological order and claims that Cybertron is the stable heart of the Multiverse.
