I was wanting to expand the description of this trope, but thought that I should post it here before doing so. This is what I wanted to add, after the initial description, but before the part about I Hate You, Vampire Dad:
"This trope is Exactly What It Says on the Tin: a father or father figure who also happens to be a prime candidate for the title of a character's Archenemy. He could be anywhere on the Sorting Algorithim Of Evil, but whether he's The Big Bad, The Dragon, or something else entirely, any story featuring him is likely to be emotionally charged at the least. Normally this will be a case of It's Personal, and may well include offers of We Can Rule Together, but not always: particularly cold-hearted fathers may declare I Have No Son! and treat the child in question as just one more problem to be solved."
Does that sound appropriate?
Would The Dark Profit Saga go under twist ending or non-spoiler examples?
Jynn is revealed as the son of the dread liche Detarr Ur’Mayan late in the first book, but the second book is titled “Son of a Liche”.
