While the Golden Age Luthor (later named Alexei Luthor) is simply an amoral and brilliant man driven by a simple desire for power, the Silver Age incarnation was given a more developed personality and backstory. Teenage Lex Luthor is an aspiring scientist who resides in Smallville and greatly admires its local hero Superboy. After Lex saves him from kryptonite, the Boy of Steel builds him a private laboratory in gratitude. After "thousands of experiments," the young scientist creates an artificial life-form of "primitive protoplasm." Overjoyed, he accidentally causes a chemical fire in the lab. Superboy puts out the fire, inadvertently spilling other chemicals, destroying the artificial life-form and the accumulated research notes that led to its creation. The chemical fumes also cause Lex's hair to completely fall out. Enraged he has lost years of research but unwilling to accept responsibility for the fire, Luthor concludes Superboy intentionally sabotaged his work, jealous of the young scientist's achievements, and swears revenge.
