->'''Played by:''' Creator/NoahWyle

A former history professor, Tom lost his wife early on in the invasion, and he was left alone to keep his three sons safe. He joined the Massachusetts Militia with his sons, but his second oldest son Ben was captured and put into a harness when the invasion began, but was eventually rescued. Tom serves as Weaver's second in command of the 2nd Massachusetts.
----

* BadassBookworm: Taught college-level American History and is one of the best soldiers in the 2nd Mass.

* [[OurPresidentsAreDifferent President Action]]: Elected President of Charleston during the time-skip between seasons 2 and 3, Tom only agreed to take the job if they allowed him to keep leading the occasional combat mission. He allowed Arthur Manchester to keep running the day-to-day affairs of government.
* ProperlyParanoid: After returning to the 2nd Mass after the aliens let him go, Tom insists that every keep an eye on him and stop him if he starts acting weird, due to his fears of brainwashing. The parasite in his left eye that Anne extracts that later escapes and goes to Red Eye shows his fears are not unfounded.

Tom's second oldest son, Ben was captured by the aliens and put into a harness while fighting for the 2nd Massachusetts. He was eventually rescued and freed from the harness, but is now suffering from some side-effects.
----
* BlessedWithSuck: Being harnessed gave him various superhuman abilities (strength, senses, etc.) and the power to communicate with Skitters, but at the cost of putting stress on his muscular structure and possibly shortening his lifespan, and also causing him to be discriminated against by other humans.

[[caption-width-right:350:''"You don't have to agree, you just have to follow orders."'']]
->'''Played by:''' Creator/WillPatton

A veteran of Operation Desert Storm, Weaver is placed in charge of the 2nd Massachusetts. He has little regard for the needs of the civilians with the unit, viewing them as a hindrance to fighting the aliens. He eventually grows out of this viewpoint and comes to rely heavily on Tom's advice.
----
* AFatherToHisMen: A harsh, tough father, but still…
* AuthorityEqualsAsskicking: As leader of the 2nd Mass. Tom Mason leapfrogs him by becoming President of Charleston in season 3 but Weaver remains his go-to guy for combat missions.
* TheCaptain: His official rank.
** Promoted to ColonelBadass in season 3.
* ControlFreak: Called one by [[spoiler:his daughter]], though this mostly manifests as him being overprotective and someone pressing his BerserkButton (badmouthing him about his family). He admits he hasn't changed much.
%%* CultureBlind
* CynicismCatalyst: Upon losing his wife and daughter, Weaver became the JerkWithAHeartOfGold we know today. His daughter, however, implies he was always like that.
* DeathGlare: He practically communicates through those.
%%* DeadpanSnarker
%%* DeliveryGuy
* TheDeterminator: You gotta hand it to a guy who is constantly injured, poisoned or under enemy fire. He ''never gives up''.
* HeartbrokenBadass: The [[TheLostLenore loss of his wife]] weighs him down quite a bit.
* HeroicBSOD: Weaver goes through one of these after being exposed to one too many reminders of the family he's lost. He snaps out of it when he finds his wife's glasses and realizes she may still be alive.
%%* HiddenDepths
* HotBlooded: Weaver isn't afraid to express his emotions.
* JerkWithAHeartOfGold: While a good person and primarily concerned with the good of the group as a whole, he tends to put the welfare and comfort of his fighters first. His HiddenHeartOfGold is best shown with his interactions with Jimmy, the 13-year-old fighter, whom he treats as a soldier ''and'' a child.
* IconicOutfit: InUniverse. Margaret and Anthony joke in season two that his rugged jacket and hat are his trademark, and indeed, he's almost never seen without those.
* KnightInSourArmor: World-weary and cynic, he remains a determined fighter for the 2nd Mass.
* TheLeader: Type II for the 2nd Mass.
* TheLostLenore: The loss of his wife (and daughter) made Weaver quite a bitter man.
* MadeOfIron: Out of the entire main cast, Weaver is the one more likely to be poisoned, shot at, stabbed or be thrown through windows, yet he survives, every time. Lampshaded very frequently, such as Mason's off-hand comment that "Weaver is made of cast iron". [[spoiler: However, these wounds are starting to take a toll on him, as seen by his recently discovered heart problems.]]
* OldSoldier: When the invasion started, his commission in the Army was reactivated. He's a career soldier before the invasion. Even when Tom becomes de facto leader of the 2nd Mass, Weaver is still at the forefront of every battle.
* ReasonableAuthorityFigure: Eventually gets to this point.
* SanitySlippage: In "Mutiny". He got better.
** Suffers a more severe one in season four. He's still sane, but he's..''off''.
* ShellShockedVeteran: Weaver was quite psychologically damaged by the conflict. He has on hell of a ThousandYardStare.
* TragicKeepsake: If you look carefully, you'll notice his hand has a small band wrapped around it. That band belonged to his now deceased wife.
* TraumaCongaLine: The universe just seems to ''pile up'' misery after misery on him. He lost his wife, accidentally killed his younger daughter, is frequently on the brink of death, acquired severe heart problems [[spoiler:and has now watched his older daughter be turned into a monster and die before his eyes]].

----

** DarkActionGirl: [[spoiler: After becoming an Espheni pawn, she becomes more ferocious and terrifying.]]
* AlasPoorVillain: Played with. In her final moments, [[spoiler: she apologized for her actions and confesses her love to Hal, ''but'' we have no clue if she was being sincere or not, and no one except Hal seems to believe her words (specially Margaret, who actually shoots her mid-sentence).]]

%%* DeadpanSnarker: More so than Hal.
* DefrostingIceQueen: Non-romantic with the entire group over time (and somewhat romantically with Hal), starting with how she treated [[ChildSoldier Jimmy]] during an attack.

%%* BigBad: Season 4.
* BondVillainStupidity: He was so focused on killing Lexi, [[spoiler: he ignores a downed Tom who is right behind them, unaware he has a poisoned syringed that can kill him]].
* CassandraTruth: He tells The Monk Lexi will rebel and disrupt all their plans, but he's ignored.
* TheChessmaster: Already shows a high-degree of skill at playing against Tom Mason, and judging by the way he talks, he seems to have a few cards up his sleeve.
* DeadpanSnarker: Scorch takes a few, subtle verbal jabs at Mason when they talk.
* DidntSeeThatComing: [[spoiler: Tom's syringe blindsided him entirely]].
* EvilOldFolks: Possibly. If you compare him to the other Overlords, you will notice his skin is far more wrinkled, maybe implying age.

* FrontlineGeneral: He is seen leading his troops directly to battle Mason, a first for the Overlords.
* IHaveYourWife: Threatens Mason with this.
* LastBreathBullet: [[spoiler: Not literally, but as Scorch lays dying he rips out the self-navigation system of his ship, essentially forcing Lexi to sacrifice herself.]]
* MadeOfIron: [[spoiler: Survives being pretty much roasted alive.]]
* MeetTheNewBoss: The promo that introduced him mentioned this exact phrase.
* ANaziByAnyOtherName: Institutes ghettos like those from World War II and uses kidnapped children in a Hitler Youth-style "New Coalition" reeducation camp. Matt explicitly mentions the parallels on the latter. Interestingly, these are the exact behaviors the first Espheni leader in the show used as an example of the worst of humanity.
* KnightTemplar: [[spoiler: He is apparently gathering an army to fight a larger threat of some kind.]]
* OnlyKnownByHisNickname: "Scorch" is all we've got.

* TakingYouWithMe: [[spoiler: Probably why he ripped off the ship's navigation device.]]

* TwentyFourHourArmor: He wears some sort of thick steel armor all the time.
* VaguenessIsComing: He warns Mason a greater evil is on the way, but he never specifies what exactly he's talking about. It is [[JustifiedTrope justified]] by the fact Mason isn't his ally and he has no reason to share intel with him.
* WardensAreEvil: We ''are'' talking about a Nazi-style ghetto of innocent people rather than an actual prison, so this trope applies in full force.

* FightingForAHomeland: However, he doubts he will ever get to see his homeland on his lifetime, commenting that he fights so the children of his children might see it.
* FirstContact: His introduction in the finale of season two mirrored many classic examples of such scenes - aside from the fact that Earth was already crawling with other alien species...
* HealingFactor: When seriously wounded he heals on his own without need for medical attention.
* IComeInPeace: Cochise and the other Volm are aiding the human resistance as of the beginning of season three, though many people are wondering whether they will turn out to be a case of WeComeInPeaceShootToKill.
