Interesting - Sentinel Prime's shield was designed for Optimus, Igor was originally Undermine and Que was originally Steeljaw. Also, I just noticed that Shockwave's Driller (originally Colossus) has three crushing gears kind of like the ones on Shockwave's back.

[Bartrim]

Que's head also resembled Q from James Bond alot more originally.
