Reviving this thread in honour of the late Jhiaxus (aka Andrew Sorohan).

Are there any other Obscure Transformers that anyone can think of (according to Jhiaxus' definition of Obscure TF; i.e. can only exist in one official medium)? Since 2019, I think some Obscure TFs can include:
* Any of the Bot-Bots who have not appeared in the TV series
* Enerax and Sheeldron. Any other Battle Masters who are original creations and didn't appear in any comics or TV show?
* All of the Fossilisers, except Transmutate
* Tonkanator
* Red Five
* Monsterbots, Cyberverse (except Repugnus)
* Doublecrosser
* Discharge (Cyberverse)
* Roadtrap (Cyberverse)
* Hyperdrive (Cyberverse)
* Hashtag, Jawbreaker (EarthSpark) & Nightshade; although they'll probably get toys later. Nightshade is already pictured on the back of the Deluxe Class box.
