History WesternAnimation / SpaceSentinels

* RobotBuddy: Sentinel-1's Maintenance Operator, "Mo" for short. He's comic relief in terms of interactions with the main three, but he's also incredibly good at his job and respected by the other characters for it.

* SpellMyNameWithAnS: Astraea or Astrea? The goddess she's named for spells it both ways, and some sources spell it "Astrea", but it's spelled Astraea on the DVD cover.

'''Astraea''': We've met before - or should I say ''since''.

* YourMagicsNoGoodHere: In "The Wizard of Od", the team visits an alternate dimension called Fansia, where their powers work oddly, when they work at all: Mercury finds himself going super-slowly when he can move at all, Hercules has no super-strength, Astra can only turn into distorted versions of herself before figuring out she [[CursedWithAwesome can turn into mythical animals instead of real ones]], and none of them can fly.

* AllMythsAreTrue: But they aren't all ''accurate''. Most "gods" are actually space aliens (like Anubis), extra-dimensional entities (like Loki), or superpowered humans (like Mercury and Hercules).
* AllYourPowersCombined: Morpheus in "The Sinister Sentinel" had all three sentinels' powers - Hercules' strength, Mercury's speed and Astraea's animorphing. He tended to use more monstrous forms than Astraea, however.
* {{Animorphism}}: Of the VoluntaryShapeshifting variety. Astraea is "able to take any living form" (though she is only shown turning into modern Earth animals).

* SmurfettePrinciple: Astraea is the only female character in the main cast. Almost averted when they team up with the Sentinel team from the planet Drakon, which consists of one man and two women, but the women spend the entire episode in stasis, so Astraea is still the only woman in the active team.

** Even after the name change, though, it's still not quite accurate: none of them are from space, though they do live in an alien spacecraft and sometimes deal with threats from space. WordOfGod says they were trying to lure in some of the ''StarWars'' audience with the new name.

* NonIndicativeName: None of the "Young Sentinels" are young. Though youthful in appearance, they're anywhere from a few hundred to a few ''million'' years old (if Hercules is actually a Neolithic-era caveman like he appeared to be in the pilot). This may be why they changed the show's title partway through the first and only season. (Even then, though, none of them are from space, though they do live in an alien spacecraft and sometimes deal with threats from space)

[[caption-width-right:200:Left to right - Mercury, Astrea and Hercules]]

The story tells the tale of three heroes — Hercules, Mercury and Astrea — who were taken out of their timestreams to a faraway world, given superpowers and sent back to Earth to protect mankind. Hercules and Mercury were based on the figures from Greek & Roman mythology but Astrea was created for the series. (In-universe, however, the mythical Hercules and Mercury are explicitly based on them)

* AllYourPowersCombined: Morpheus in "The Sinister Sentinel" had all three sentinels' powers - Hercules' strength, Mercury's speed and Astrea's animorphing.
* {{Animorphism}}: Of the VoluntaryShapeshifting variety. Astrea is "able to take any living form".

* FriendToAllLivingThings: Also Astrea. She can understand all animal languages and can befriend any animal, even ones normally terrified of humans.

* LatexSpaceSuit: Mercury and Astrea's costumes.

* RobotBuddy: Sentinel-1's Maintenance Operator, "Mo" for short.
* ShapeshifterBaggage: There's apparently no size limits to what Astrea can turn into, from mouse to elephant.
* SmurfettePrinciple: Astrea is the only female character in the main cast. Almost averted when they team up with the Sentinel team from the planet Drakon, which consists of one man and two women, but the women spend the entire episode in stasis, so Astrea is still the only woman in the active team.
* SpeedSmartsAndStrength: The PowerTrio is composed of Hercules, a Nordic blond male with tremendous strength; Mercury, an Asian male with phenomenal speed; and Astrea, an African female with metamorphic powers. Since Astrea, in most of her forms, is still the most vulnerable of the three, she's also an excellent tactician.

'''Astrea''': We've met before - or should I say ''since''.
* TokenMinority / TokenTrio / TwoferTokenMinority: Mercury is Asian (implied to be Chinese in "The Wizard of Od" and "The Sorceress"), Astrea is black (her original outfit appears to be Egyptian), and even Hercules is AmbiguouslyBrown (though he might just have a good tan).

* WalkingShirtlessScene: Hercules.
* WingDingEyes: Mo expresses non-verbal communication with these, especially question marks when confused.

* AllYourPowersCombined: Morpheus in "The Sinister Sentinel" had all three sentinel's powers - Hercules' strength, Mercury's speed and Astrea's animorphing.

* YourMagicsNoGoodHere: In "The Wizard of Od", the team visits an alternate dimension called Fansia, where their powers work oddly, when they work at all: Mercury finds himself going super-slowly, Hercules has no super-strength, and Astra [[CursedWithAwesome can only turn into mythical animals]].

* SpeedSmartsAndStrength: The PowerTrio is composed of Hercules, a Nordic blond male with tremendous strength; Mercury, an Asian male with phenomenal speed; and Astrea, an African female with pleomorphic powers. Since Astrea, in most of her forms, is still the most vulnerable of the three, she's also an excellent tactician.

* AdaptationalVillainy: Even ignoring he's an alien and not an actual deity, Anubis is referred to as the god of darkness and a being of evil in the hieroglyphics, when the actual figure is anything but that.
