Prototype

S6, E21: Lex has been clandestinely trying to turn Wes Keenan (TAHMOH PENIKETT), a military man who supposedly died fighting in Afghanistan, into a supersoldier by injecting him with DNA pulled from the various meteor freaks Lex has captured. After a corrupt Senator, Burke (ALAN C. PETERSON), threatens to expose the secret labs, Lex dispatches Wes to kill the Senator, but Lois witnesses the attack and inadvertently becomes the supersoldier's next target. Meanwhile, Clark tries to convince Lana to leave Lex.
