TF: Prime | TF: Robots in Disguise (2014) No noses? No problem! Zombiebots? Sure, why not. A confusing new canon that allows loose and contradictory material? And now a new sequel show with an entirely different art style that takes place way in the future!
Modern Comics / Generations | Universe | Classics The modern comics universe has had such a different take on G1, one that's significantly represented by the Generations toys, so they share a forum. A modern take on a Real Cybertronian Hero. Currently starring Generations toys, IDW "The Transformers" comics, MTMTE, TF vs GI Joe, and Windblade. Oh wait, and now Skybound, wheee!
Transformers Live-Action Movies Money, violence, sex, computer graphics, scatalogical humor, racism, robots designed to be rednecks but given European accents, and maybe another sequel to the saga... what's not to love? TF m1, Revenge of the Fallen, Dark of the Moon and now Age of Extinction.
Other TF Lines Ancillary, non-main-line stuff. Star Wars TF, Speed Stars, Titanium Series, Robot Heroes, that sort of thing. They're kinda neat, but we all know they're not really that important. Admit it, you know it's true.
TF: Animated Some cartoon with big chins and a little girl that got beloved by fans and taken off TV to make way for a different show on another network. Yeah, that's fair.
RiD | Arm | Ener | Cy Acronyms and abbreviations are fun. That, or these lines don't deserve quite enough respect for full names. Robots In Disguise, Armada, Energon, Cybertron - there, that's their names, happy now???
Beast Era "What? Transformers made from animals instead of vehicles and stuff? Doesn't sound so great, throw it to Kenner division, maybe they can make a quick buck or something." Beast Wars, Machine Wars, Beast Machines... seeing a pattern? Coming soon: "Wars Wars"
G1 | G2 The originals... ok, not exactly, but the original named "The TransFormers" anyway. Take THAT, Diaclone! Generation 1, Generation 2 - Removable fists? Check. Unlicensed vehicle modes? Check. Kickass tape deck robot with transforming cassette minions? DOUBLE CHECK!!!
