The Transformers: Rise of the Beasts toyline coincides with the seventh film in the live-action film series. Much like the merchandising for Bumblebee, the film's self-titled toyline is focused on kid-oriented products, with the collector-targeted figures released instead as part of the ongoing Studio Series line, co-branded with the film's title.
Labeled by store listings as "Core Boys" products (not to be confused with the Core size class seen in other toylines), these figures use the traditional Deluxe and Voyager size classes but without the "premium collector product" approach of Studio Series, akin to the Deluxe Class offerings in the recent Cyberverse and EarthSpark toylines, and were based on early film concept art due to time constraints.<ref>SDCC 2023 Hasbro Show Floor Q&A – Legacy, Studio Series, Video Games, More!</ref> The Core figures' distribution differed depending on country, with the USA getting the Deluxes exclusively in two Target box sets (see below) and the Voyagers as Walmart exclusives, while everywhere else had normal distribution of individually packaged figures. Additionally, the Core line was not offered through the usual large online retailers such as Amazon for reasons unknown.
The "Beast Alliance" subline focuses on gearing up characters using beast partner figures that transform into weapons or armor. The Beast Battle Master and Battle Changer assortments offer individual beasts and allies, while the more expensive Beast Weaponizer and Beast Combiner pricepoints pack together a figure with a beast partner.
Drawing upon molds created for the Bumblebee Energon Igniters toyline, the "Autobots Unite" subline features vehicular characters who can be propelled in alt-mode by an "energon core" motor, packaged with the larger Power Plus and Nitro Series products. Much of the line is unchanged re-releases, with a few redecos. This subline was not carried by the major retailers Target and Walmart. The Speed Series and Power Plus Series toys were also referred to as "Spark Racers" and "Spark Chargers", respectively.
The remainder of the Rise of the Beasts toyline comprises a variety of products not branded as part of any larger subline, including a number of robot-to-roleplay-accessory items, Flex and Smash Changers with transformation gimmicks, electronic Beast Mode figures, and the standard Titan Changers assortment. TakaraTomy's large Optimus Primal figure was imported via Hasbro Pulse and other online retailers. Towards the end of the line's run, more package refreshes of Bumblebee Energon Igniter figures were released under the returning "Legends of Cybertron" name.
A number of Rise of the Beasts toys were released in the Target-exclusive Buzzworthy Bumblebee toyline. For those markets, this was the only way to get the Core Deluxe figures.
Following the pattern established by its predecessor Bumblebee, the collector-focused toys in the Rise of the Beasts line were produced under the umbrella of the evergreen Studio Series collector toyline of movie product. All toys branded as Rise of the Beasts tie-ins are listed below.
Jada Toys released replicas of the vehicle modes of multiple characters from Rise of the Beasts. The 1/24 scale toys other than Optimus Prime came with a die-cast Autobot badge standee.
Much of the toyline, such as the "Core" toys and the entire Autobots Unite subline, was found at retail without a prior announcement from Hasbro.
The first Rise of the Beasts toy was originally the Buzzworthy Bumblebee "Energon Escape" Bumblebee and Optimus Prime two-pack. The co-branding on the packaging was later changed to the Bumblebee film, presumably due to the one-year delay of Rise of the Beasts.
