Bonus options (because the poll only has six options):

Chekov:

Chapel:

Rand:

I think I'm going to go with McCoy and his sassy "tell it like it is" attitude, but Spock's very much a close second.

I think everybody else would be pretty much tied for third after that. :-P

Tie: James T. Kirk & Spock

Doctor Leonard H. (“Bones”) McCoy, son of David, is close behind!

And I love Nyota Uhura! I had the great good fortune to meet Nichelle Nichols. She was beautiful, warm, and gracious!

All of the above.

All of them. The team is the hero.

Agree with @Fandyllic & @Hurga

The USS Enterprise,’NCC•1701, is also part of the team and a hero!
