My favorite design was TFTM Bumblebee (classic camaro) - but I'd go with Blackout/Grindor or ROTF Megatron as the most badass. Why? Blackout/Grindor was the design so nice, they used it twice & Megatron for shredding into Starscream when he pinned him down with his foot.
The Constrcuticons were awesome. I really with they'd get represented better in a future piece of media, or via a third party. I'd love a classics-based ROTF Mixmaster, Scrapper, and Rampage.
I liked Laserbeak (despite kind of being a turkey) he was freaking huge and intimidating. DOTM Megatron is still my favorite though. Blackout had a good one too.
Man, it took this many pages for someone to mention one of my favorite movie designs? RAMPAGE! Anyway, my list: Megatron (DOTM) Optimus Prime Rampage Sideswipe Soundwave (DOTM) I kept it to five. EDIT: ^yes! this is why! Also, AOE Grimlock if he turns out to be as jawesome as the leaked stuff.
The first to come to mind Dino/Mirage. Sideswipe (I loved the rolly feet) Soundwave (DOTM) Mixmaster And I ended up liking Starscream's design the moment I heard him called 'Dorito of Doom." Can't unsee a flying Dorito dropping bombs.
FUCK IT...... ALL OF THEM...but seriously the group who makes these concepts should get a pat on the back...oh and mv1 blackout for president
I loved the designs of all the characters with a few exceptions. I especially like Barricade, Sideswipe, Shockwave and Mixmaster
The Wreckers had the baddest alt modes. All of those guns, rockets and exposed machinery coming from a racing car; priceless! Baddest bot mode was probably Blackout. He had that propeller for slashing through enemies and just a scary silhouette.
