* CompleteMonster: The Titan [[BigBad Cronus]] after he escapes from Tartarus (where he was imprisoned for being an evil tyrant and for trying to [[OffingTheOffspring kill his kids]]). He waste no time in seeking to resume his dominance over the world and all in it. With nothing but hatred for his children and the other Gods, Cronus is utterly brutal and merciless in his tactics, which include [[ColdBloodedTorture torturing]] and [[AbusiveParents trying to kill his own children]] while throwing the world into chaos and disarray. Cronus eventually gets tired of the human heroes resisting him and makes it a point to attempt to [[KillAllHumans exterminate the entire human race]] in retribution. At other points, Cronus releases the [[SavageWolves savage werewolf]] Lycaon from imprisonment to eat "whomever he may please" and tries to get his [[AlmightyMom mother Gaea]] to kill Zeus for him. [[FauxAffablyEvil Sophisticated, suave, seemingly polite]] and never at loss for a vicious plan, Cronus repeatedly proves how nothing will stand in the way of his goals of domination and destruction.
* FanPreferredCouple: For whatever reason, Herry and Niel are the most popular pairing for each other, and one of the most popular ships in the fandom in general.
* MostAnnoyingSound: During their expedition to Atlantis, Neil frequently says "Ping!" for no other discernible reason than that it annoys Archie half to death.
* UncannyValley: In "Cronus 2.0", Odie devises a computer program that simulates Cronus. Hephaestus builds a robot to utilize the program for training, but the resemblance to the actual Cronus terrifies Theresa. [[spoiler:With good reason, as it turns out.]]
