Many were both confused and surprised that Titans Return Ramhorn was not a datapad to interact with Titans Return Blaster, mirroring the interaction of the G1 toys, and instead having Ramhorn just be a Titan Master. Well, you have to give Hasbro some credit because what they give you instead is something for the ages. You see, Japan had designed a ton of head only characters, here is a diagram of the lot of them.
Only a few made it to production with a finished product such as Lione...
...and Shuffler
Both of which are in the Titans Return line.
Well, take a look at this head, which was never made in the G1 era, and which turned into a rhinoceros.
This is the design used in the Ramhorn head the Titan Master turns into.
So this head is not just a take on G1 Ramhorn in Titans Return but it is also that Japan only character which was to be released with Lione, Shuffler and the others. And it is finally happening 30 years later. Like Shuffler and Lione, the animal the head would have turned into back in G1 is now a Rhinoceros vehicle for the Titan Master to interact with.
So this is a deep cut from Hasbro showing that old designs we think will never see the light of day actually get brought back.
