Knowing the Internet, probably a lot. And while it is good practice to write that kind of stuff, much may change by the time you ever do get onboard a show.
Easy bit on my part:
If forced to use Prime, BB and Ratchet (I'm writing scripts for a five-part pilot/pitch called Skeleton Crew that has eight Autobots and four Decepticons plus 90% of their mooks from FOC), I'll aim for a more IDW/Marvel Ratchet, WFC BB, who is very bitter about losing his voice, and have Prime not be so dull.
BTW, how much flak would I catch for including the Heroic Chrysler 300 I take my username from (he's an OC)
