Frank Castle → The Vampire Diaries

Role: A human investigator who comes to Mystic Falls looking into a string of suspicious disappearances and quickly realizes the town is hiding something.

Personality: Quiet, intimidating, brutally direct, observant, and intensely protective.

Friend: Alaric Saltzman — both are practical, suspicious of supernatural chaos, and used to dealing with problems nobody else understands.

Partner: Jenna Sommers — both are adults, grounded, and protective. Jenna isn’t impressed by Frank’s intimidating act, while Frank respects that she can hold her own.

Biggest flaw: He has trouble letting go of a mission once he believes someone deserves justice.

Reputation: The guy in Mystic Falls everyone learns not to underestimate.

Signature: Black clothes, an old pickup truck, coffee, and standing silently in the corner while everyone else argues.

What stays: His discipline, loyalty, determination, bluntness, and protective instinct.
