Generations Nightbeat never really scratched that itch sadly; he looked okay, but his transformation was fiddly, his robot mode had far too many bits and pieces flopping around unsecured, and his chest dragged along the surface in var mode. =/
Wipe Out and Wilder it coulda been: Wipe Out is down in the dumps because the Scramble City Trypticon was destroyed and left him a drifting to the point he arrives in Legends World, he finds Wilder and both go on a crime spree subverted by their realisation neither gets any joy from it until they stop a violent crook together and become anti heroes. (Bass XO beat me!)
Yes, Nightbeat and Siren would have been easy remolds of Chromedome - just give them new chests and each other's Titan Master heads. Fangry and Squeezeplay would be remolded from Twinferno with their own Titan Master heads. And Horri-Bull would have been remolded from Wolfwire.
Even more weirdly, it was the early shift where some people had their regular day off for the week, while the late shift was supposed to have full attendance (not counting sick days, vacations and overtime reduction).
