History Characters / StargateSG1SG1

The token female of the team. Like Daniel Jackson, served as the voice of reason, as opposed to O'Neill's gung-ho approach to problems. As a doctorate scientist, was the source of much {{Technobabble}} and AppliedPhlebotinum, usually [[MacGyvering jury-rigged]] to solve this week's problem. Throughout the seasons, she went from "reasonably brilliant" to "genius who would be bathing in Nobel Prizes if not for the secrecy of the Stargate Program". Later promoted to full-bird Colonel and [[{{Transplant}} joined]] the [[Series/StargateAtlantis Atlantis Expedition]] after ''SG-1'' was cancelled. As of ''Series/StargateUniverse'', she has been given command of the ''Daedalus''-class battlecruiser ''George Hammond''. Appeared in more ''[[Franchise/StargateVerse Stargate]]'' episodes than any other character.

* VaporWear: She appears not to have been wearing anything under a Kull Warrior suit in her first appearance. She's shown in a form fitting jumpsuit when she removes the armour, but that might have been part of the undersuit.

* AcePilot: It doesn't come up too often, but she managed to single-handedly commandeer the ''Prometheus'' in a matter of hours, and she disrupted the first Ori supergate using a pretty fancy bit of flying. Whenever the team needs to use a Goa'uld ship in the final two seasons, it's usually either her or Teal'c at the controls.

* AscendedExtra: Vala was intiailly intended to be just a one-shot character for "Prometheus Unbound". However, positive reception to the character's debut (and Claudia Black's fantastic chemistry with Michael Shanks) led to Vala being brought back as a recurring character for Season Nine and then ultimately promoted to Main Cast for the final Season and TV Movies.

%%* ConMan: woman.

* HeelFaceTurn: Downplayed, since she was never really a villain. She's introduced as a oneshot antagonist and initially has ulterior motives for tagging along with the team when she returns the following season, but after realizing the threat posed by the Ori she grows increasingly conflicted, eventually culminating in her HeroicSacrifice. When she returns the ''second'' time, she throws in her lot with the team for good and makes a concerted effort to leave her old ways behind her.

* AuthorAvatar: Like [[ExecutiveMeddling the network]] that insisted on keeping the SG-1 title for the name power rather than change it into [[{{Aftershow}} Stargate Command]] like the producers wanted, Mitchell decided to recreate SG-1 rather than assemble his own team.

* RememberTheNewGuy: During his first appearance it's revealed that he was critically injured saving the lives of SG-1 during the battle of Antarctica and that each member of the team went to visit him in the hospital at least once, despite the fact that none of them have ever mentioned him before. Since the previous season finale involved time travel, this has led some to speculate that he didn't actually ''exist'' until the timeline was changed.

* AuthorAvatar: Like [[ExecutiveMeddling the network]] that insisted on keeping the SG-1 title for the name power rather than change it into [[{{Aftershow}} Stargate Command]] like the producers wanted, Mitchell decided to recreate SG-1 rahter than assemble his own team.

%%* AuthorAvatar

%%* ContrastingSequelMainCharacter: Both to O'Neill ''and'' to [[Series/{{Farscape}} the last character his actor played]], to the point where the only things he has in common with both are being an AcePilot and a DeadpanSnarker.

* BadassNormal: He doesn't have the Ancient Gene, he wasn’t Special Forces trained, he never hosted a Tok'ra, and he's not an alien badass, he's just a normal earthling. He still kicks plenty of ass.

* ChillyReception: Downplayed; the original members of the team are perfectly friendly when he first arrives, but when it comes to actually being under his command both Daniel and Teal'c were often annoyed by his inexperience and not afraid to let him know. They eventually warm up to him, however, and by the end of his first season he's a member of the TrueCompanions.

* MyGreatestFailure: He once bombed a convoy, after asking for and receiving confirmation that it contained the target. ''Immediately'' after he released the bomb, he was told to hold his fire. The convoy was destroyed, and it turned out to be carrying refugees. He was considered blameless, but it haunted him for the rest of his life; and he almost resigned over it.

* BadassBaritone: Easily the character with the deepest voice outside of the Goa'uld.

%%* ContrastingSequelMainCharacter: Both to O'Neill ''and'' to [[Series/{{Farscape the last character his actor played]], to the point where the only things he has in common with both are being an AcePilot and a DeadpanSnarker.

* TheChick: She fits the role compared to the other members of the team and is more overtly "feminine" coded than Sam.

* GoingNative: At the end of the movie, he chose to live on Abydos with his new friends rather than returning to Earth.

* MasterOfDisguise: Not in the physical sense, but as a professional linguist he's actually very good at pretending to be a foreigner speaking accented English. When he needs to come up with a fake persona in the second season episode "1969", Jack is surprised that he nonchalantly thinks he can pull it off, to which Daniel matter-of-factly says "I speak twenty-three languages: pick one". He then convincingly passes himself off as a German scientist by adopting an authentic German accent.

* TheMcCoy: Bases his decisions on emotions rather than rules or reason. One time he wanted to bring an extra SG team to a planet that was conducting a murder trial for Teal'c. His {{plan}} was to show off his BiggerStick and hope they surrendered. His motivation was saving a teammate and he was willing to violate every law on that planet (and several on his own) to make it happen.
* ManChild: He sometimes acts like this when he is relaxed and off-duty. While stuck in a time loop in the episode "Window of Opportunity", he takes the opportunity to do things like bicycle jovially through the base, use mustard and ketchup to squirt a funny face onto a paper plate, and launch golf balls through the Stargate.

* HotScientist: Yes, she's a brilliant astrophysicist and engineer, and yes, she's good-looking enough to turn heads without half-trying. (Literally: poor Sergeant Siler once [[DistractedByTheSexy walks into a wall after catching sight of her and Vala in street clothes]].) Even the Goa'uld Hathor upon first meeting her calls her "an exceedingly beautiful woman".

* BikerBabe: Though we never actually get to see her riding it, it's been shown that she enjoys tuning up her motorcycle in her downtime, and in one episode she turns up late to a briefing still in her leathers with helmet under her arm.

* NiceHat: Wears a variety of chapeaux whenever he has to go in public, including a fishing hat, fedora, cowboy hat, a fake afro and a headband.

* BaldBlackLeaderGuy: He was in charge of Apophis's armies as First Prime.

* ExpositoryHairstyleChange: He initially has long hair in an unfashionable style similar to the movie, but it gets cut short at the end of season two and remains that way for the rest of the series, highlighting his moving away from the HollywoodNerd persona and increasing badassery. It's also around this time when he becomes a lot snarkier, and a lot less naive, indicating a slightly darker personality.
