Heatwave

Chase

Blades

Boulder

Ik their eye colours are wrong, but hey they're autobots too so they have to have blue eyes, right? Also Boulder looks kind of better with blue eyes, and the others having heterochromia (Blades having sectional heterochromia while Chase and Heat have normal Heterochromia) are pretty cool too.

Which one is your favourite RB in general.

I don't really have a favourite since they're all very adorable, but mine would have to be Heatwave, he's a grumpy boi who can be a bean when he wants to.
