trying to make a list of all g1 characters for my own personal obsessiveness and the fiction characters are giving me a bit of grief.... between the g1 toon and the marvel US/UK comics there was quite a few characters that never had toys(back in the day anyway) such as Arcee, Unicron, Alpha Trion, the rainmaikers, devcon, straxus, impactor and so on... im trying to create my own file/database for future reference but beyond the quite prominant ones i know off the top of my head it becomes harder to search for them..... any help or pics/scans would be muchly appreciated!
The old website 'Obscure Transformers' have some of that: The Archive! It's pretty cool. Have you read Last Stand of the Wreckers? The Decepticon team Squadron X in that includes really obscure Marvel comics Decepticons: Squadron X - Transformers Wiki
Category:Comic-only Transformers - Transformers Wiki Category:Cartoon-only Transformers - Transformers Wiki Category:Fiction-only Transformers - Transformers Wiki
Macabre - black shadow Ferak - cyclonus Triton - energon sharkticon Fang - ? Tornado - ? Earthquake - ?
Since you said 'fiction G1 characters' and not 'fiction G1 Transformers' I'm gonna throw in Death's Head and Centurion. They're not Transformers, but they are robots and are cool.
