I would say that i am Soundwave since iI love music so much and i have a bird named Lazerbeak but my dogs name is Maggie and not Ravage..too bad. I also will open a can a whoop ass when needed just like Soundwave. Oh yeah!!!
Definately Starscream! I'm ruthless just like he is trying to go up the "corporate ladder." I've been known to be somewhat of a smart-ass as well. I'm the lead man on my job (but not the boss) so I can sympathise with Starscream about never getting the respect I so truly deserve.
I would say STARSCREAM, since it would be cool to transform into a Jet and be able to fly is my primary reason to be him.
I am no leader myself, but if and when I see someone mess up as a so called Great Leader then I would go try to take his/her place and become the New Leader like STARSCREAM tries too in the old cartoons. LOL
