Most franchises reboot by decade; Transformers reboots by generation — and its cartoons matter exactly as much as its movies. The 1986 animated film traumatized more children than any Bay explosion, Beast Wars is secretly a sequel to the 80s cartoon, and the live-action saga can’t agree with itself about its own first contact. One thing has never changed since 1984: Peter Cullen is Optimus Prime. We mapped all of it, medium by medium.

Five generations, and the medium changes with each: a cartoon-verse (with a theatrical movie inside it), a CG sequel wearing a disguise, a five-film live-action juggernaut, a soft reboot that won’t say the word, and a fresh animated origin. The dashed card is our honesty marker: the cartoon multiverse between Beast Wars and the Bay films is real, large, and mapped here in summary — each of those shows is its own continuity.
All 11 entries — in release order
Everything checkable on this page, in the order it arrived — cartoons and films side by side, because in this franchise the cartoons are not the side dish.
The Bayverse problem — a continuity at war with itself
The five Bay films are one continuity on paper and a demolition derby of retcons in practice — each sequel rewrites when the Transformers first reached Earth, and the 2018 soft reboot contradicts the film it’s supposedly a prequel to. This tab is the honest ledger; no fan-theory glue, just what the films actually claim.
Optimus & Bee — the constants
Across five continuities and forty years, two characters carry the brand — and one voice. Here’s the honest throughline, including the on-screen death count nobody’s parents were ready for in 1986.
The toy box — where all of this actually comes from
Transformers is the rare franchise where the toys are the source material. The lore, the names, even the deaths — all of it traces back to product decisions, and knowing that makes the mythology more interesting, not less.
Where to start — roll out
Eleven entries, five continuities — nobody needs all of it at once. Each door below is honest about which universe it opens.
Beyond the screen — panels, pixels & the road ahead
Some of the best Transformers stories ever told aren’t on this page’s checklist at all — they’re in comics (where the lore was invented, and later perfected) and a pair of games widely considered the brand’s finest hour.
