John Frederick Paxton

"Terra Prime forever."

- Paxton, in his address to Starfleet Command

John Frederick Paxton is a villain appearing in two episodes of Star Trek: Enterprise.

He is played by Peter Weller, who would go on to play Alexander Marcus in the film Star Trek Into Darkness.

History
As a young man, Paxton originally studied to be a historian until he, by his own admission, got into a heated argument with his instructor. At one point in his life, he contracted Taggart's Syndrome, a disease that required regular injections of Rigelian gene therapy to prevent death.

Paxton became the leader of Terra Prime, an anti-alien movement. He ordered the creation of a Vulcan/human hybrid created from the DNA of Enterprise crewmembers Commander Charles Tucker III and Commander T'Pol to serve his own ends.
