Ok if you finish single player look at the concept art for autobots recruits. Their is a concept for a guy that looks a whole lot like ultra magnus. Thier is alos a red and white guy but i have no idea who he is. in Decepticon soldiers theri is a pic of Dead end and onslought. Very cool.
We think the blue and white guy is scattorshot. Image:CD Scattorshot toy.jpg - Transformers Wiki As for the white and red guy I'm not sure which one you're takling about but te last guy is the generic autobot drone. Dead End and Onslaught are indeed very cool
There is no pic of Onslaught in the Decepticon art, just for the record. Its just another pic of Brawl.
yeah, that's Onslaught, he looks exactly like that in the DS game, his portrait is even straight from this drawing
From the looks of it Onslaught would have been a leader in multiplayer, and "Scattershot" a soldier. In other words the missing Autobot soldier chassis and missing Decepticon leader chassis. Weird.
The DS-only concepts were done by the DS team, so you won't see them in the home console game's gallery.
