I know I'd shit my pants if I saw Bonecrusher rollerblading down the freeway in the direction of my car.
Probably none of them.... Of course if I saw em in person, that'd be different, but just in the movies, no...
The Barricade - Sam scene, kind of evoked that sense of human fear a bit. Imo it was trying to copy the feeling of Terminator 2's scene where the T1000 chases John Connor on his bike.
the only one that comes to mind is Demolishor, he's way scarrier then Devastator. Devastator just looks stupid, but Demolisher on his own is a kick ass scary lookin dude!! They should have just left him solo in the movie
I guess Barricade. Both in alt and robot mode he is pretty intimidating.. but I guess more because of his actions. He was the only Decepticon to get that close and personal to a human (that I can remember... and not counting Frenzy). I was actually pretty surprised how he kept revving his engine and threatening to run over Sam... and he wouldn't stop, either. I mean you'd think 2 or 3 times would give the hint that he isn't screwing around.. but he really wanted to scare Sam. I was pretty surprised he did that as many times as he did. But of course any one of them would be pretty scary in real life and have me running in the opposite direction.
Scorponok defintely... I'd do in my paints if a giant metallic scorpion suddenly would burst out of the ground !
Hard to say until I've seen the second movie. If they are the jump up and then just drop over dead types it's sort of hard to be scared of something that's easy to kill. And how the heck did Ravage not make it on the list? With all those teeth and everything that should have at least gotten the kitty a spot on the poll.
