War For Cybertron: Earthrise is a subline imprint of the Generationstoyline, and the second portion of the War for Cybertron Trilogy.

First revealed in late-2019 at New York Comic Con, War for Cybertron: Earthrise is a direct continuation of Siege, carrying over the C.O.M.B.A.T. System. Most toys are once again covered in 3 mm and 5 mm posts to accommodate the previous effect parts from Siege and the Deluxe Class range from Cyberverse. Continuing in Earthrise are the Micromasters and Battle Masters. Battle Masters (which now primarily turn into shields/ramps) still include additional effect pieces that can be placed onto other weapons included with other size classes, as well as hardpoints on the figures themselves to simulate being 'shot' or on the back of vehicles to simulate "rocket boosters" or "speed", depending on the effect part. Micromasters also feature these additions and retain their weapon mode combinations. Another carryover from Siege is relative robot mode scale, with the Leader Class figures being smaller, Voyager Class-sized figures that come with additional parts to beef up the price (except for Doubledealer). Heck, some Siege figures even got re-released in this line!

The new primary gimmick of the toyline is the "A.I.R. Lock System" (Adaptable Interconnection Retrofitter) that involves ramps that can hook up to various toys and connect them to each other, forming a giant battle station. This is supplemented with certain Deluxe Class Modulators, that can break down and form armor or weapons, and add on to other stations using the modular system, effectively replacing the Weaponizers of Siege. Earthrise also returns to traditional Earth vehicle modes, rather than the Cybertronian vehicle modes of Siege, and few of these releases feature battle-damage style paint.

Inside the package for every toy in Earthrise, in the middle of the cardboard backdrop, is a clip-and-save piece of the "Transformers Universe Map", following the Ark's journey to Earth. These pieces can be cut out with scissors and combined to form a larger map, depicting many of the familiar planets and other interstellar locations from the history of Transformers fiction. Larger figures (Deluxe, Voyager, Leader) include a translucent red decoder to view the map's labels and hidden paths. The Voyager, Micromaster, Battle Master, and a few other backdrops contain map segments that help to complete paths, but they lack labeled locations. Unfortunately for some Siege fans, Earthrise figures that are re-releases from Siege do now include unique exclusive map pieces in their new Earthrise packages.

Unusually for a Generations toyline, the mass-retail portion of Earthrise ran for less than a full year, beginning in each assortment's second wave of 2020 product and running through to the end of the same year. Additionally, the worldwide coronavirus pandemic saw an atypically long gap of roughly nine months between the line's debut and the next round of releases.
