Great question!
As someone who grew up watching G1, but didn't have access to any of the toys on shelves (at least until the commemorative reissues came along) I definitely had a wish list in mind.
In all honesty you could've given me anything G1 and I would've loved it, but these are the characters I recall obsessing over the most.


Powermaster Prime (yes specifically him because of the super robot mode)
Bumblebee
Jazz
Ironhide
Swoop
Springer
Ultra Magnus

Starscream
Devastator
Astrotrain
