Lightspeed (Earth-9107)

Looking in from the outside, you'd think Lightspeed (aka Lightstorm or Lightsteed) had it all: He's highly intelligent, strong, fast, and considered dashingly good-looking by Transformers standards. And if any of that mattered to him at all, he'd be golden. Sadly, Lightspeed aches down to the core of his being for something more. His heart yearns to escape the bonds of gravity and fly free. Dreams of soaring between the stars and exploring the vast mysteries of space consume him, making him feel slow, trapped, and dissatisfied with what others would see as a charmed existence. Lightspeed would gladly pursue his dream of being rebuilt as an interstellar spacecraft if the Autobots' situation wasn't so grim. As it is, he knows the necessary resources are more valuable elsewhere and so puts his energy into winning the war and making his dream a possibility. His dreams tend to distract him from his current function as a data processor.

Lightspeed is allergic to energon (and most other fuels to a lesser extent) and must take a special lead sulfide additive when fueling or he experiences severe engine knocking and a bad rust rash.
