The Strain/Characters

Badass Normal: For a street punk, he does a pretty good job surviving the vampire plague.
Cain and Abel: His relationship with his brother, Felix, is not a good one, but this trope is played more straightforward when Felix is turned into a vampire and Gus is forced to kill him.
Even Bad Men Love Their Mamas: He never stops caring for his mother. Not even when she becomes a vampire.
Jerk With a Heart of Gold
Hot Blooded
Gang Bangers
Unwitting Pawn: In the sequel, The Ancients manipulate him into becoming their agent.

Arch Enemy: To Abraham Setrakian.
Ax Crazy: Even compared to the other Ancients.
Badass Grandpa: Manages a particularly cool moment where he escapes the main party out a window into direct sunlight, where (while burning) he calmly removes his cloak, gives a roar, and escapes. Granted it took a while for him to heal, but damn.
Big Bad
Body Horror: Even more than the other vampires, since his host was suffering from gigantism.
The Chessmaster
Complete Monster
Genius Bruiser
Hive Queen
Monster Lord
The Virus
