7/2/11 Image:Doac jpg.JPG Jazz Shark Jackknife Wheeljack (emitted by Calliope) Perceptor (emitted by Ratchet) Just off the Repair Bay and behind heavily reinforced doors is a crowded but carefully organized lab complex. Jackknife and Crackshot have their own labs here, as well as the larger main lab shared by the Autobots' most notable (or notorious) scientists, Wheeljack and Perceptor. Both of them are in the lab today, working on projects and talking quietly but excitedly about something on the workbench in front of them. Ratchet's voice can be heard shouting profanity in the Med bay.
