YOU DO NOT HAVE TO APPLY AS ONE OF THE CHARACTERS ON THIS LIST! As long as they are canon and from TOS (or an original character per the rules), you may apply as them. Just make sure to fit their bio to match STXI and keep in mind that any history that has happened in TOS hasn't happened and probably won't happen.
If you need any help with ideas on characters to apply for, there is a great master list here at Memory Alpha.

James Kirk is the brash, young, and head-strong captain of the
USS Enterprise. He was born during the attack on a ship his
father was stationed on, the USS Kelvin, and barely made it
out alive. For a goodly portion of his life, he was a juvenile
delinquent and he hated to take orders from others. With a
helpful push from Captain Christopher Pike, he eventually
enlisted in Starfleet and ended up going on a wild adventure
that resulted in him being promoted to Captain of the
Enterprise within 3 years.

Hikaru Sulu is the USS Enterprise's helmsman. He's a brilliant pilot
and is also quite skilled in sword fighting. He feels he
owes a great debt to Kirk since he saved Sulu's life
while on a mission. Because of this, he's usually one
of the only people that will back up Kirk in an argument.
He's a little shy, but he's also very friendly and determined.

Chekov is a bright and optimistic seventeen-year-old mathematical
prodigy who has quickly risen through the ranks of
Starfleet due to his determination and extreme diligence.
He's fresh from Russia and is still having trouble speaking
fluently in English. He's also one of the only people to ever
be assigned to a ship before the age of 18. Thankfully his
friendly demeanor and outgoing attitude helps him establish
relationships with his peers easily.

Spock is the Vulcan first officer of the USS Enterprise and
is also a close friend to Captain James T. Kirk. The culture
of his race requires him to flush out all emotion and to only
act with logic. After the destruction of his home planet, he
softened up a bit, letting his heart do some of the deciding
every once in a while. He's the foil to Kirk's brash attitude.

Leonard McCoy is the first person Kirk befriended when
he was on his way to Starfleet Academy. "Bones," as his
friends call him, enlisted in Starfleet as a last resort after
his wife divorced him and took everything he owned
(including the "whole planet"). He's always sticking his neck
out for other people and knows how to do his job damn well.
However, he has slight aviophobia.

male, 29, doctor, (your choice)
Doctor M'Benga is a Starfleet medical officer who serves aboard
the USS Enterprise. In the event of Dr. Leonard McCoy's
absence, M'Benga is the ranking chief medical officer. Due to his
outstanding bedside manner and his ability to keep calm and
cool-headed during the most hectic situations, he's usually the
first person people see for a second opinion.
male, 24, science officer, (your choice)
Lieutenant Rodriguez is a bit of a ladies man. He's also very
good at his job and he likes to let everyone know it. Sometimes
though, his pride gets the better of him and can lead him to dangerous
situations that he can't control.
female, 24, communications officer, zoë saldana
Uhura serves as communications officer aboard the USS Enterprise
under the command of James T. Kirk. While she was at
Starfleet Academy, she was the Academy aide for the

courses. She is proficient in 83% of official Federation
languages and regional dialects. Uhura is in a romantic
relationship with Spock, her former instructor. She also has
an ongoing playful conflict with Kirk.

Scotty is the quite brilliant Chief Engineer of the USS
Enterprise. Before his promotion, he had been stationed
on planet Delta Vega, due to a failed experiment in which
is transported Admiral Archer's dog somewhere unknown.
He often tries to lighten a situation by telling jokes and he's
a true Scotsman at heart (he loves his scotch). As long as
no one insults the ship, he's a very sociable fellow.

female, 21, yeoman, your choice
Janice Rand enlisted in Starfleet at a very young age and
was assigned to the USS Enterprise after Kirk was promoted
to Captain. She now serves as Kirk's Yeoman on the bridge.

first to his side to see what he needs when things go wrong.
