I suppose Bug Bite could be added to the list based off his release in the Collectors Edition 6 pack and Timelines releases?
My list is really for just characters that appeared in G1 media or in G1 toys between 1984 and 1993 when original G1 ended. If you guys really want G1 characters that have been to the G1 canon post-1993 then I guess I could add them if there is demand.
I have a list of all G1 characters that have been released in CHUG form. You can find it here. Please feel free to let me know if I got anything wrong so I can fix it.
