Associated fiction generally repurposed the Titan Masters as Headmasters and Godmasters (with larger Transtector bodies), though in toy terms, they remain cross-compatible with the Titan Master head swapping gimmick. The Titans Return compatible toys in Legends are as follows:

Evidently thinking they'd mastered the concept, Hasbro and Takara would frequently dip back in the Titans Return well whenever a toy necessitated Titan Master engineering. The toyline for the live-action movie The Last Knight, which overlapped with the tail end of Titans Return, introduced a pair of molds to represent new Titan Master-compatible characters. Elsewhere, existing tooling would be used to represent anything from new takes on old characters to real-life Japanese celebrities. New toy designs based on Titan Master engineering were still being produced for the War for Cybertron Trilogy toylines in 2020, four years after the debut of Titans Return; of these, Earthrise Snapdragon would herald a sea change in terminology, with his product copy referring to his small partner Krunk as a Titan Master and Headmaster interchangeably. The G1 nomenclature was retained for the subsequent Retro Headmasters line, which brought certain Legends toolings to Western audiences, and it also appeared in the product write-up for Buzzworthy Bumblebee Fangry and Brisko.

Power of the Primes
Following Titans Return, the next and final instalment of the Prime Wars Trilogy was Power of the Primes. This line featured the unified gimmick of "powering up", whether that meant gaining the abilities of one of the original Thirteen Primes, combining, or evolving to Primehood.
Prime Masters
The line introduced the Prime Masters – small robots directly based on the engineering of the Titan Masters. Instead of transforming into heads, the Prime Masters could become "spark modes" to slot into the Prime Armor of various figures, or into the Matrix handles included with the larger toys (see below). These spark modes were essentially Titans Return head modes, but with the front faceplate replaced by the insignia of that particular Prime; this meant that Titan Master heads could fit into the aforementioned Prime Armor, and Prime Master spark modes could be used as heads for Titans Return compatible figures — though with the latter, your mileage may vary on how well each Prime insignia resembles a face.

Enigmas of Combination/Matrix cores
Deluxe and Voyager Class toys in Power of the Primes revisited Combiner Wars-style combination, augmented by the addition of "Prime Armor" accessories that could house Prime Masters (and by extension, Titan Masters and Headmasters) in any of their configurations. Each Deluxe figure included a Prime Armor chestplate that could form a combiner hand; each Voyager figure came with a pair of bracers that could double as combiner feet, as well as an Enigma of Combination accessory to slot into the mounting port of any of the Prime Armor pieces.
Meanwhile, toys in the Leader Class price point each included a two-piece Matrix accessory, consisting of a frame in the shape of the Matrix of Leadership's handles and a block designed after its crystalline core. The Matrix cores were, surprise surprise, the same general shape as Titan Master heads, Prime Master sparks, and the Enigmas of Combination, so each of those things could be mounted into the Matrix's handles. Do you want your Rodimus Prime to open his chest to reveal a Matrix with an effigy of his own face? Now you can!
We mention all these accessories on this page because, despite not turning into little robots, both the Enigmas of Combination and the Matrix cores feature the characteristic neck post compatible with the Titans Return play pattern, meaning you can plug them right in and give your robots greebly cyclopean heads with no neck articulation. You know, if you wanted to.
