Obscure Transformers

[Handsprime]

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.

* Shotimus Prime (depends if this one counts, as it's an Alternative version of Armada Hot Shot who managed to get the Matrix of Leadership, and his appearance is based off Universe (2003) RID Optimus Prime)
* If Shotimus Prime counts, then Optimus Prime (Universe 2003) counts as well, although that's even more debateable.
* DK-2 Guard
* The Junkions in Legacy Evolution
* Shadowstrip (if he counts as a seperate character, and not G2 Drag Strip)
