Barricade exists but how about Blackout or two versions of the same character, like what IDW1 did with Breakdown. Maybe Bayverse Bonecrusher as a seperate character than G1 Bonecrusher, for example?
Nitro Zeus being the goddamn chad he is. also Cogman, Shatter, Dropkick, Blackout, Scalpel and a Crosshairs that's AOE based rather the G1 version.
Tons, a lot of the Movie characters have a ton of potential -Bonecrusher -Crowbar -Hatchet -Dino -Que -Leadfoot -Stinger -Nitro Zeus -Dreadbot -Mohawk -Onslaught -Shatter -Dropkick
Shatter and Dropkick come to mind. Bay!Bonecrusher as a separate character from the Constructicon. Cogman would be nice to see. He's about the only thing worth salvaging from TLK. Nitro Zeus.
