So, this old dude
waltzes in and beats the living hell out of someone or something, and you already know who they are. They are, in fact, the main character's Father
. Often times, he'll be beating up the main character, unless the protagonist is female, largely because he wouldn't hit his dear sweet daughter
. The guy doesn't have any reason to be so powerful, and it doesn't necessarily mean the hero isn't fighting back because of filial loyalty. Basically, he knows Parent-Fu. Because he's your daddy, he's more powerful than you, which makes this a subtrope of Authority Equals Asskicking
It should be noted that this encompasses perception. Just because the author explains everything later
, doesn't change the fact that they were running on Parent-Fu at the time. Compare with knowing mortal combat
for an equally flimsy justification for a character's power, contrast with most other forms of -Fu in that the character need not have any training.
Anime and Manga
- In Bleach, Ichigo's Father is able to take down Grand Fisher, seemingly for no other reason than being the father of such a Bad Ass.
- Also in Ranma ½, not quite a father but a grandfather - amnesiac Shinnosuke's grandfather always uses the "Megaton Punch" whenever his son forgets anything important.
- Pootie Tang's Dead Father in Pootie Tang, who was demonstrated to be able to strike anywhere at any time with his belt, with lightning speed. This was temporarily explained as a magic belt, but was later explained as him being simply that BadAss. Further, he was only demonstrated being this way with Pootie Tang, which was a very real case of being powerful because he was Daddy.
- Robert "Granddad" Freeman from The Boondocks, who demonstrates a remarkable skill with the belt and is at least Huey's (who has proven himself ridiculously capable for his age) equal in combat, for no clearly stated reason.
- Comedian Sinbad had a routine where he described his mother's particular ability to punish him, including spanking him so hard his butt fell off, then launching her hand Rocket Punch-style when he ran. Which, of course, lead to the immortal line "It's your momma's hand! Drop your butt and run!"
