Mr.Bradward Boimler, because he's the relatable, downtrodden Everyman of Star Trek, doing his best, stressing out, and screaming in terror every day of his life. I just want to hug him.
Plus, he might be a boring worker drone, but inside that drone is an ambitious little weasel, and inside that weasel might be a tiny human being.
And he has purple hair.
