History Film / Subspecies

* BigBrotherBully: Radu is very much this to Stefan in the first Subspecies movie.

* PoliceAreUseless: The police do not believe Becky about the vampires in Bloodstone and Bloodlust. Not helped that the closet thing to a ally she has in the police force is Lt. Marin who is a antagonistic incompetent moron.

* SavedByCanon: Considering Subspecies 4 takes place before Vampire Journals [[spoiler: we know Ash and Serena will not die-at lest in that movie]]

** Michelle's sister Becky and US Embassy Mel Thompson were major supporting characters in Subspecies 2 and Subspecies 3 who helped to fight Radu and rescue Michelle. In the opening of ''Bloodstorm'', Becky and Mel were literally killed off in an accidental car crash while transporting the body of a sleeping Michelle, kicking off the events of the film. Their faces were not even shown (Obviously, their actors in the previous films did not reprise their roles). Other than a short moment of Michelle sobbing over their deaths, nothing was ever mentioned about them again.

* DeathByCameo: Angus Scrimm of {{Film/Phantasm}} is billed first in the first Subspecies movie, however he is killed in literally the first scene of the movie.

* TheArtifact: The titular Subspecies... do next to nothing in the series. They're really only there because Full Moon productions always have at least one stop-motion element (usually [[TheMerch so they can sell models and action figures of them]]).

** Lt. Marin himself is this to Becky, who states that he just naturally makes her angry.

* CainAndAbel: Radu is the Cain, the evil elder brother to the younger and half-human Stefan. Radu indicates that even before the two engaged in a duel to the death, Radu had spent many centuries delighting in tormenting Stefan when he could.
* CallForward: ''Blood Rise'' does this at the conclusion [[spoiler: where Radu reflects how Helen tormented him even after he had killed her, as they cut to a scene of Michelle (strongly suggested to be the reincarnation of Helen) drinking from the Bloodstone.]]

* FallenHero: According to the summary of ''Blood Rise'', Radu started off as a warrior of the Catholic Church sent to retrieve the Bloodstone from his father, whereupon he became a full-blown monster.
* FaceHeelTurn: Radu as once was once a honorable noble solider who fought against evil. However after being used and embracing his vampire nature, he became a monster.

** They're everywhere in ''Blood Rise''. Most egregiously, Radu's father is portrayed as an insane, monstrous beast, even ''after'' he acquired the Bloodstone, despite the first movie making it clear that it was the Bloodstone that pacified him. It's heavily implied that Stefan is a ChildByRape instead of the consensual offspring he was suggested to be in the first movie, which, additionally, makes Stefan weeping over the body of his father and wanting to avenge him look extremely awkward.

** Radu's subspecies form at the end of ''Bloodlust''. However, come to the next sequel, they are nowhere to be seen.

* MyGodWhatHaveIDone: Subtle, but when the high of his victory over Stefan has faded, Radu truly seems to regret murdering his brother. When his mother inquires of the "bastard boy," Radu's look is ''not'' one of triumph. When she states love is not for the likes of them, Radu protests he truly loved Stefan and wishes he hadn't killed him.
** Radu has the same reaction too in ''Bloodlust,'' when he kills [[spoiler: his mother]]

* StupidEvil: Ash insists on being as much of a prick as he can be, abducting Sofia — who has friends that know she was there — and eventually turning her, and killing Anton's lawyer, Walter, both of which would certainly bring attention to his club. Iris calls him out on this.
