3rd Rock from the Sun/Characters

Core Regulars
Dr. Dick Solomon (John Lithgow) - High Commander of the aliens. Played by Lithgow as a Large Ham, Dick is an Insufferable Genius when it comes to science and a Ted Baxter when it comes to everything else. He is in love with Mary Albright and Mary Albright alone whether she likes it or not. His Earth job is as a physics professor.
 * Comically Missing the Point: Doesn't understand sarcasm or lying very well.
 * An example would be when Mary compared his family to The Addams Family. Dick assumed she meant second president John Adams. When she states that wasn't what she meant, Dick thinks she meant John Quincy Adams and becomes enraged that she would compare his family to "that freakshow".
 * Did I Just Say That Out Loud: Once blurted out to his class that Earth would be destroyed by a meteor in 2015.
 * I Can't Believe Its Not Heroin: Got addicted to collecting stuffed animals called "Fuzzy Buddies". His friends and family staged an intervention when it reached the point that he had so many he was keeping them in the freezer.
 * Professional Butt Kisser: Admits he became High Commander by doing this.
 * Sadist Teacher: While handing out a test to his class, he openly told them that none of them would be able to solve question four, which made up half the test.
 * He's actually really bad at what he does. Tommy's pointed out that he's had the same students in his class for six years.
 * And Mary witnessed his pathetic attempt at teaching a little girl to play hopscotch in the park, which resulted in the little girl running away while Dick hurled insults at her.
 * Single Target Sexuality: A subversion. Mary is the only woman with whom Dick considers himself to be truly in love with, and spends the length of the entire show either with her or trying to get back together with her. But he's had other relationships, including a one-night stand with the mother of one of his students.
 * Sitcom Arch Nemesis: Had three, the only frequent one being Vincent Strudwick. The other two were fellow alien Liam Neeson, and grumpy lunch lady Lucy.
 * What Does He See In Her?: The other aliens hate Mary and don't understand what Dick's obsession with her is. As the series progressed their opinion of her as a person softened, but they still hated the idea of the two of them together.

Sally Solomon (Kristen Johnston) - Security Officer and Dick's "sister". A Hot Amazon who didn't like being "The Woman" at first, but eventually discovered that being a six-foot-tall blonde bombshell has its advantages. Works as the Solomons' homemaker despite being a Lethal Chef.
 * Action Girl
 * Ax Crazy: Borders on this at times, such as when her role as the security officer would require having to kill someone deemed a threat to the mission. Her solution to stop an auditor from discovering they're aliens was to snap his neck, and then the necks of everyone they encounter on the way home.
 * I Can't Believe Its Not Heroin: Was once addicted to buying shoes. Tommy commented that she had more shoes "than Italy". It reached a point that she was sleeping on shoe boxes.
 * I Have Boobs You Must Obey: Gradually learns how to use this
 * I Want My Beloved to Be Happy: In the last two episodes she turns Don into an effective police officer and gives him a backbone before leaving Earth, because she couldn't stand the thought of him spending the rest of his life as a muffin making coward.
 * Mama Bear: Has the potential to be one.
 * Their First Time: People are shocked to learn that someone of Sally's looks only recently lost her virginity to someone like Don.

Tommy Solomon (Joseph Gordon-Levitt) - Information Officer and Dick's "son", who is Really Seven Hundred Years Old, but got stuck at Compulsory School Age. He was in High School for most of the series, but he eventually graduated and went to college, at which point he was more-or-less demoted to Recurring Character.
 * Did Not Get the Girl: Actually, he did get the girl. But Sally misconstrued Alissa's thoughts on graduation to her wanting to break up with Tommy, so she told her that he was breaking up with her. He had two chances to get back with Alissa afterwards, and blew both of them. The first, Tommy wound up telling everyone at graduation in his valedictorian speech about how they made out on her parents bed. The second, he tried to sacrifice Alissa to save himself when it appeared that there was some maniac brandishing a power tool in Alissa's backyard. It was Sally and Harry pulling some hair-brained scheme to push the two back together again.
 * Grumpy Old Man: Tommy's actually the oldest of the aliens, and quite pissed that he's in a young body subjected to raging hormones.
 * Important Haircut: In season four he finally gets his hair cut. This is around the time Joseph Gorden-Levitt started to get older.
 * Traumatic Haircut: Stated that he actually missed his longer hair.
 * Only Sane Man: Among a quartet made up of a Ted Baxter, a Hot Amazon, and a Too Dumb to Live Kavorka Man.

Harry Solomon (French Stewart) - Dick's "brother", Harry is the "transmitter" with which they contact the Home Planet. A ditzy, Chick Magnet and all-round Wacky Guy who never seems to open his eyes all the way.
 * The Casanova: He's easily the oddest of the aliens, yet he has had the most relationships with gorgeous women who could easily do better than him.
 * His romantic interests have included Vicki Dubcek, Nina, an alien played by Cindy Crawford, a body builder policewoman named Janice, and in the last episode we find out that for the entire show he'd secretly been with.
 * Cloudcuckoolander: Worst of the four.
 * Eyes Always Shut
 * Flanderization: When the series began Harry was just as odd, only quiet and a little subtler. As the seasons went on he started becoming louder.
 * Genius Ditz: He's not very bright in terms of book smarts, but he's the most artistically gifted and has surprisingly no trouble dating women way out of his league. He also cracked the bar code.
 * I Want My Beloved to Be Happy: He told Vicki that she should stay with the Big Giant Head because he was sincerely trying to do right by her and Eric Travis, and he didn't want Dick to get punished for disobeying orders.
 * Kavorka Man
 * Likes Older Women: Has been with.
 * Too Dumb to Live

Dr. Mary Albright (Jane Curtin) - Dick's (initially reluctant) Earthling love interest and an anthropology professor at his college. She is a neurotic Christmas Cake who was a Good Bad Girl in her younger days, a fact which Dick seemed to be oblivious of in earlier episodes. "Mary: Dick, I can't have children.
 * Bottle Fairy: Borders on this. She's known at the local supermarket as the "White Zinfandel Lady".
 * Actually came in handy, as this rendered her immune to the drugged wine given to her by Charlotte from "Alien Hunter". Of course, it didn't help when she knocked Mary out with the gnome.
 * Broken Bird: Her alternate universe counterpart "Kiki" is this, a bitter and cold woman who doesn't believe in love anymore. Mary has the potential to be this, but she actually handles all of the stress of a horrible childhood and a somewhat crappy career better than you would expect.
 * Child Hater:

Dick: Oh Mary, why not?

Mary: Because I﻿ hate them."


 * Dude Where's My Respect: She found her thesis in the bottom of box labelled "Sugar Puffs".
 * Dysfunctional Family: Her parents both had affairs while she was growing up (including one that draws doubt to Mary's paternity). She's the eldest of three children, all twisted in their own ways. Her brother Roy sells aluminum siding and tells women he was abducted by aliens as an attempt to get laid. Her sister Renata is an affected, wealthy woman who has a personal vendetta against Mary and does everything in her power to destroy Mary's life (including trying to steal Dick). Their whole family seems fond of alcohol, and Mary has apparently followed in her mother's footsteps to become a borderline Lady Drunk.
 * First Name Basis/Last Name Basis: Dick initially calls her "Dr. Albright", but permanently switches to "Mary" after they hook up. The other aliens refer to her as just "Albright". Nina and Vicki call her "Dr. Albright" while the other professors call her "Mary".
 * Hilariously Abusive Childhood: Well, maybe not "abusive", per se. Her parents were close to emotionally abusive, however, and this is played for laughs.
 * Love Triangle: Managed to have not one, but two relationships with two different alien beings.
 * My Beloved Smother: Her mom's a complete bitch.
 * My God What Have I Done: Had this moment when she realized she had sex with Dick while locked in the school library, under intoxication. This was during one of their "break up" periods.
 * Not That Kind of Doctor: Not matter how many times Mary has to explain it, Vicki keeps thinking that the "doctor" in her name means Mary's a medical doctor.
 * Ted Baxter: Once compared herself to Abraham Lincoln in a speech to her colleagues. And, in Nina's words, "he did not come out favorably".
 * What Does She See in Him: Her relationship with Dick.
