John Martin (Challenger)

John Martin is a Human Male who lives in the 22nd century and services the United Earth Starfleet as first officer onboard the and later on the  Challenger, under the command of his ex-wife Marcia Taylor. (Star Trek: Challenger)

Early Life
John Martin was born on August 3, 2129 to James and Maria Martin in San Diego, California on Earth, sometime in the early 22nd century. He appears to have a good, albeit somewhat irksome relationship with his parents who are very nurturing and friendly but a bit quirky and lacking in personal boundaries. John apparently dreamed of being a starship captain from a very young age and took every opportunity to learn and prepare for it.

Starfleet Academy
eventually enrolling into Starfleet Academy, where he met Marcia Taylor, a beautiful, fiery, and like-minded young woman whom he would eventually marry.

Martin was at the top of his class at the Academy, surpassing all his peers by a wide margin. Upon his graduation into the United Earth Fleet, John worked tirelessly day and night on multiple ships to advance up the ranks and secure both a ship of his own. With it, a stable future for himself and his new wife, Marcia, who like him had also graduated from the Academy. John's obsessive work-ethic evidently put considerable strain on his marriage to Marcia, who claimed she tried on numerous occasions to talk about it but that John would simply shut her out, while John retorted that she never showed any appreciation for his supporting them and working for their future.
