Imagine a Punisher reboot; the catch is he has a daughter. Maybe adopted by him from a situation in which she had no family left- just like him.
She'd be one of those little girls who's into skulls and wearing black but instead of being emo, she just likes it.
And Frank comes home to her early in the morning just in time to make her some skull-shaped pancakes for breakfast, and a sandwich for lunch at school that has the crust cut off and is in the shape of a skull.
Just imagine the obligatory issue taking place in her preteen years when a boy shows up at the door asking to take her out on a date.>M-Mr. Castle? Sir?>Don't Sir me. Don't you ever Sir me. You must be Kevin. Tell me Kevin, you do your homework?>Y-Yes, Mr. Castle, s--yes.>Good. Kids should do their homework. Adults should do their homework too. Parents -- good parents should do their homework too. And I've done mine, Kevin Savioli. Son to Martha Burns and Eric Savioli. Born January 10th, 2000. A real "turn of the century" kid. Hobbies include basketball, painting, and watching cartoons. Tell me, what kind of cartoons?>I... I dunno, Cartoon Network, uh... Adventure Time?>I want you to look me in the eye when you're lying to me, Kevin. Look me in the eye and tell me if I seem the kind of man who'd ask you your favorite cartoons without having gone through your hard drive first?>... Aw jeez.>Frank calls her down for breakfast and she happily greets him and eats pancakes while nonchalantly ignoring the fact that he's still drenched in the blood of slain criminals from the night before>Frank playing with vampire Barbies with his daughter>They have pretend tea parties>The whole time he keeps his Frank face>they play hide and seek with huge over the top Nerf guns>Frank has 100 different killshot opportunities at any given moment>he lets her win and plays dead as she mercilessly fires everything she has at him>she tries scowling all the time>he tickles her until she stops
