They wouldn't have necessarily looked out of place - as many of them would have transformed into vehicles, like Cheetor (who shares the same body type as Blurr). Rattletrap & Stampy share the same body type as Ransack so presumably they transform into bikes. Spittor and Slapper transform into these kinda bipedal jumping fighting machines with "tongues" that's froglike, but they aren't actually frogs. Longrack looks inspired by Cybertron Longrack, who transforms into a crane (the construction vehicle, not the bird). Deoth Charge's alt mode kibble suggests that he transforms into a jet (which isn't so bad considering that his BW namesake's vehicle mode was a kind of jet).

Primal Major would be the most likely to sport a beast mode, and it's said that his origin story would have tied to Blackarachnia. The others would simply be regular vehicular moded Transformers who happen to sport aesthetic designs/motifs that resemble BW characters.
