Transformers Collector's Guide: Size Classes, Studio Series vs Legacy and Every Collector Line

Forty years ago, a cartoon film killed off Optimus Prime and sent a generation of kids home from the cinema in a state. 2026 is the 40th anniversary of The Transformers: The Movie, and Hasbro has spent the year marking it with a steady run of 1986-inspired figures. If that has pulled you back into Transformers, or you're buying for someone it has, welcome back. It has got a bit more complicated since 1986.

This is our standalone guide to the robots themselves: what the size classes really mean, how Studio Series differs from Legacy (and from Age of the Primes, which replaced it), and the collector lines from other makers that sit alongside Hasbro's own. If you want the story of Hasbro as a company, plus its Marvel and Star Wars lines, our Hasbro collectibles guide covers all that.

Forty years of robots in disguise, in one paragraph

Transformers launched in 1984, when Hasbro took transforming toys made in Japan by Takara and gave them names, factions and a cartoon. Takara (now Takara Tomy) is still Hasbro's partner, co-developing the figures and running its own Japanese lines. Since then the robots have been through Generation 1, Beast Wars, Armada, the live-action films that started in 2007 and 2024's animated Transformers One, and almost every one of those eras now turns up in the modern toy lines. That's the root of all the confusion: Hasbro isn't selling one Transformers, it's selling forty years of them at once.

Size classes: what Deluxe, Voyager and Leader actually mean

The single most useful thing to know: the class tells you the price bracket and roughly how much toy you get, not how important the character is. Here's how the classes look across the figures we list, with the robot-mode heights printed on our product pages.

• Core Class (about 9cm): Small, simple and cheap. Age of the Primes dropped Core Class completely, so these now mostly come from older Legacy and Studio Series waves.
• Deluxe Class (about 11–15cm): The workhorse size, and home to most of the cars and the minibots. New Studio Series and Age of the Primes Deluxes are £25.99–£27.99 with us at the time of writing.
• Voyager Class (about 16–18cm): More parts and a meatier transformation. Jets, tanks and the bigger villains live here. Around £35.99–£37.99.
• Leader Class (about 18–22cm): Centrepiece figures for the big names. Studio Series 86 Megatron is £53.99 and the Rise of the Beasts Scourge £54.99.
• Commander Class: A Leader-sized robot plus a big extra, usually a trailer or partner. In 2026 Age of the Primes got two Commanders instead of a Titan.
• Titan Class (50cm and up): City-bots, spaceships and monsters. 2026 was the first year Studio Series got the Titan slot, with the main Generations line going without one.
• Multipacks and combiners: Judge these as a set. The Age of the Primes 3-pack of Mirage, Bluestreak and Ironhide is £90.99, which works out cheaper per robot than buying three Deluxes.

Two things catch people out. First, height doesn't track the badge: our Studio Series 86 Hot Rod is a Voyager at 14cm, because the Voyager price is paying for engineering, not inches. Second, scale only holds within a line. The same character can be a Deluxe in one line and a Voyager in the next, depending on how big he's meant to look next to everyone else.

Studio Series vs Legacy vs Age of the Primes

This is the question we get asked most, so here it is plainly. Hasbro runs two collector lines side by side, and at its New York Comic Con panel this year it spelled out the split: Studio Series is about accuracy to the source and true scale, while the Generations line (Legacy, now Age of the Primes) is the playground where the designers can try stranger ideas. It expects that difference to get sharper from 2028.

Studio Series (2018 onwards)

• What it is: Robots as they appeared on screen, in scale with each other, in numbered boxes with a backdrop behind the figure.
• Its sub-lines: the live-action films (from the 2007 film to Rise of the Beasts), Transformers One, video-game characters (our Devastation Bumblebee and War for Cybertron Thundercracker are both Studio Series), and the 86 line for the 1986 animated film. That's the "86" on the box, and it's the busiest corner of Transformers right now thanks to the anniversary.
• Buy it if: you love a particular film or game and want it to look exactly right.

Legacy (2022 to early 2025)

• What it was: the main Generations line for three years, running as Legacy, then Legacy Evolution, then Legacy United. It pulled characters from every Transformers era into one shared style.
• Where it stands: finished. Legacy United's fifth and final wave came out at the start of 2025, so what's left is what's still in the system. That makes Legacy a good hunting ground for end-of-line figures, like the Legacy Evolution Breakdown at £25.99 or Voyager Nacelle at £20.99.

Age of the Primes (2025 onwards)

• What it is: Legacy's successor and the current Generations line. It's built around the Thirteen, the original Primes of Transformers lore, alongside characters from across the whole franchise.
• What's coming: the 2026 range added Quintus Prime, Sureshot, Quickstrike, Junkion Jalopy and Amalgamous Prime, and Hasbro has already shown 2027 figures including Onyx Prime and a Machine Wars Starscream, so it isn't going anywhere.
• Buy it if: you want Beast Wars, Armada, Animated and G1 robots standing together on one shelf, or you're into the deep lore.

Can you mix them? Legacy and Age of the Primes are designed to stand together, so mix away. Studio Series has its own scale, and its 86 figures copy the animation models closely, so a Studio Series 86 Megatron and an Age of the Primes G1 robot won't look like they came from the same cartoon. Plenty of collectors mix them anyway. Just know that's what you're doing.

The other Hasbro lines on our shelves

• Retro G1: modern figures of eighties characters in vintage-style boxes. Not reissues of the original toys. Retro G1 Wheelie is £25.99.
• Icons: the Optimus Prime that turns into the Autobot logo instead of a lorry. £42.99, and guaranteed to start an argument.
• Timelines: alternate-history figures. The current ones come from the Hearts of Steel comic, where the robots wake up in the 1800s, so Optimus Prime turns into a steam train. Our Optimus Prime and Starscream set is £33.99.
• Crossovers: Hasbro's collaborations with other brands, which make brilliant gifts for people who don't collect Transformers yet. We have Hot Wheels cars, Sonic, Scooby-Doo, Stranger Things and even NFL team robots.

Collector lines beyond Hasbro

Hasbro licenses Transformers to other makers too, and they split neatly into two camps: the ones that transform and the ones built purely to look good on a shelf.

The ones that transform

• Takara Tomy Masterpiece: the top end of transforming Transformers. Redesigned versions of G1 and film characters, with the most complex engineering and closest-to-the-cartoon looks of any official line, and prices to match.
• Takara Tomy Missing Link: a lovely idea. These are imagined "reissues" of what the eighties toys might have been, keeping the vintage look and transformation but adding modern articulation.
• Robosen: robots that convert themselves, no hands required. Our Flagship Optimus Prime figures run from £1,150.99 for the 1986 movie's Fallen Leader edition, and the Soundwave is £1,287.99. Very much a centrepiece, not a toy box resident.

The ones that don't

• threezero MDLX and DLX: articulated display figures with a die-cast metal frame. MDLX starts at £93.99 for Bumblebee; DLX is the big film-scale line. Our threezero guide goes into the detail.
• Super7 Ultimates and ReAction: cartoon-faithful G1 figures. Ultimates are around 19–20cm and packed with accessories; ReAction are 10cm retro-style figures from £13.99. More in our Super7 guide.
• Yolopark AMK: model kits you build yourself, no glue needed. AMK Pro G1 Bumblebee is £72.99. See our Yolopark AMK guide.
• Iron Studios Demi Art Scale: 1/20 scale statues, about 29–35cm tall, from £448.99 for Soundwave.
• Fanattik replicas and pins: the Matrix of Leadership replica at £26.99 is one of our best-selling Transformers items full stop, and the mystery pin badge blind boxes are £5.29.

And if you'd rather be a Transformer for an evening, the Transformers roleplaying game from Renegade starts with the Roll Out beginner box at £16.99.

So which one should you buy?

If the 1986 movie is your Transformers

• Studio Series 86 Leader Megatron (£53.99) is the big one, and the 86 Voyagers like Skywarp (£35.99) fill out the Decepticon side.
• The Matrix of Leadership replica (£26.99) is the one everyone is buying this year. Light our darkest hour, and so on.

Shown: Transformers Matrix of Leadership Replica

If it's a first Transformer, or for a kid

• Buy a Deluxe. Transformers One Orion Pax or Bumblebee (£25.99 each) are characters younger fans already know, with a transformation that won't end in tears. Hasbro rates them 8+.

If you want a shelf that covers all of Transformers history

• Age of the Primes. Start with a Voyager from the Thirteen, like Vector Prime (£37.99), then add the eras you love.
• The G2 Dinobots Leader 2-packs (from £43.99) are a lot of robot dinosaur for the money.

If you're after a bargain

• Look out for figures our distributor is reaching the end of. At the time of writing that includes Studio Series 86 Leader Optimus Prime at £35.99 and Transformers One Voyager Alpha Trion at £19.99. When those are gone, they're gone.

If it's a gift for someone who doesn't collect (yet)

• A Hot Wheels or Sonic crossover figure, a mystery pin badge or the RPG beginner box. All cheap, all fun, none of them need a lecture on size classes.

If it's for display, not play

• threezero MDLX for poseable metal, or an Iron Studios statue if you want something that will never be accidentally transformed by a visiting nephew.

How ordering works with us

A few Transformers are on the shelf, but most of our range comes in from our European distributor as pre-orders brought in especially for you: you order, we order, and it ships when it lands. New waves are proper pre-orders with release windows. Each product page shows its own availability and timing, so trust that over anything in a blog post.

With the anniversary in full swing, popular figures are selling through quickly and turning up online at silly prices afterwards. Pre-ordering is how you avoid that. Browse Pre-Order On Demand and Collectibles Pre-Orders.

The honest bit: what we'd swerve

• Expecting Studio Series and Age of the Primes to match: they're built to different rules. Mixing is fine; being surprised by it isn't.
• Assuming every release is a new figure: repaints and redecos of existing moulds are common across every line. Check the listing if you think you might already own it in another colour.
• Starting a full set of the Thirteen on impulse: it's thirteen Primes, released across several years. Decide early whether you're in for the long haul.
• Leader Class for a young child: bigger means more steps and more stiff joints. A Deluxe is far kinder for under-tens, and keep the instructions.
• Paying anniversary resale prices: if you missed a figure, wait for a restock or re-release before paying a reseller double.
• Binning the backdrop: every Studio Series box comes with one. Box collectors should keep it, and so should anyone who might sell later.

The short version

• Size classes are price brackets: Core, Deluxe, Voyager, Leader, Commander, Titan, smallest to biggest.
• Deluxe is the sweet spot for first figures and budgets.
• Studio Series is screen-accurate and in scale with itself; the 86 line is the 1986 movie.
• Legacy is finished; Age of the Primes is its successor and the current mix-every-era line.
• Masterpiece, Missing Link and Robosen transform; threezero, Super7, Iron Studios and Yolopark kits are for display.
• Pre-order the anniversary figures you want rather than chasing them later.

Browse everything in our Transformers collection, or the wider Hasbro range.

Final thought: forty years on, the best Transformers advice is the same as it was in 1986. Pick the robot you love, buy the Deluxe first, and try not to cry when Optimus dies.
