That list is the remaining pre-movie characters from the cartoon, and Octane wasn't in the cartoon before the movie, and the deluxe Insecticons weren't in the cartoon ever.

I think some that list ignores that all of those characters were released in Generations form, and most of them in the Prime Wars trilogy, so there are options 'for the shelf' at the moment - although your scale and cartoon accuracy mileage may vary.

I'd like to see all of the deluxe Insecticons too, outside of the Chop Shop version of Shrapnel, the other three are the never "CHUG'd" orphans of the 1984-85 lines.

(And yeah the Omnibots too but mailaways sort of exist over to the side there)
