James "Jim" T. Kirk, Captain of the USS Enterprise. Good looking with blonde hair and blue eyes. A charming and witty man with a flirtatious streak, he's known for his Maverick attitude and capability for greatness. Despite being a bit of a wild card, Kirk is an excellent leader and always does what he thinks is morally right. He cares more about people than he does for obeying the rules. He became one of the youngest captains in Starfleet history, being promoted from a cadet after his instrumental role in saving the Federation from a Romulan attack. Pike originally convinced him to join the Starfleet because he believed Kirk could do great things. He became great friends with McCoy at the Academy. At first, Kirk clashed greatly with Spock due to their differences, but they have a deep respect for each other and quickly became friends.

First Officer and Commander of the USS Enterprise. Half Vulcan, half human. Tall and lean with dark hair, dark eyes, and pointed ears. His Vulcan heritage gives his skin a slightly green hue. Always logical and composed, he was raised with Vulcan customs but never truly fit in because of his hybrid nature. Many assume Vulcans are devoid of emotions. Despite his stoic demeanor, he is deeply loyal to his friends and willing to make sacrifices for the good of others. As a Vulcan, he is extremely disciplined with much greater strength than a human. He is capable of touch telepathy through his hands and therefore avoids physical contact unless necessary. Spock is a former instructor at the Starfleet Academy and known for programming the Kobayashi Maru scenario. A year ago, his home planet of Vulcan was destroyed by a Klingon attack and his human mother was killed. Devastated by her loss, he stepped down as Captain of the Enterprise and Kirk took his place.

Secretly Khan Noonien Singh. He's known under the fake identity John Harrison. Tall and muscular with sharp cheekbones, black hair, and piercing blue eyes. A master tactician with a commanding presence, mysterious plan, and unwavering ambition. He is relentless in his pursuits and believes wholeheartedly in his own superiority. For unknown reasons, John Harrison has begun a one-man rebellion against the Starfleet, with a personal vendetta against Admiral Marcus. No one knows he is a genetically augmented human from the past with greatly enhanced strength and intellect who once took over half of earth. Admiral Marcus secretly unfroze him and used him to create weapons against the Klingons, threatening his still frozen crew to keep him compliant. Khan hid his crew in the weapons he built in an attempt to smuggle them out but believes they were killed when Marcus discovered them.

Doctor Leonard "Bones" McCoy. Chief Medical Officer of the USS Enterprise. A cynical and sarcastic technophobe, he is an excellent physician and carries a deep reverence for life. Despite his grumpy and cantankerous attitude, he is quick to for others.

Nyota Uhura, Lieutenant and Communications Officer of the USS Enterprise. Unmatched in Xenolinguistics, she is a highly efficient officer known for her intelligence.

Patel Chekov. Ensign and navigator of the USS Enterprise. A young Russian man with an innocent demeanor and a golden heart.

Montgomery "Scotty" Scott. Chief Engineer and Second Officer of the USS Enterprise. A fiercely dedicated, proud, and pragmatic man with a Scottish accent.

Admiral of the Starfleet under the command of Marcus. He's the former captain of the Enterprise and mentor to both Kirk and Spock.
