Perry became an OWCA agent at a very young age. He had a knack for martial arts, he was at the top of his class in training school, and he surpassed some of the greats during training exercises. It's no wonder he became Danville's top agent after only a few months in the field. He was everything he was "supposed" to be: suave, secretive, silent, stoic. A perfect soldier.
That changed quicker than he'd like to admit. After spending two weeks with the Flynn-Fletcher family Perry became absolutely whipped for their kids. He would do anything for them in an instant. They weren't the only ones to melt his heart though.
He had been given his nemesis assignment in the same week: Dr. Heinz Doofenshmirtz. Perry read the case file until he knew it by heart. There wasn't much there:
Name: Dr. Heinz Doofenshmirtz
Threat level: High
Age: 41
Height: 6'2
Nationality: Gimmelshtump, Drusselstein
Blood type: AB+
Affiliations: Mother—unknown, Father—unknown, Mayor Roger Doofenshmirtz (Brother), Charlene Doofenshmirtz (Ex-wife), Vanessa Doofenshmirtz (Daughter).
Note: Heinz Doofenshmirtz has split custody of Vanessa Doofenshmirtz.
Perry had always known that Heinz had a daughter.
At first, Perry thought OWCA misjudged Heinz's threat level. The man spent way too much time monologuing, his schemes were petty and full of holes, and he was way too nice. There were several occasions that Heinz offered Perry food to be a good host/nemesis. The food wasn't even poisoned, Heinz would take a bite after Perry "refused" with silent glares. There was no way this man was a "high" level threat.
That opinion changed in record time. Heinz is a very capable scientist, his petty backstories prove he can be triggered by the smallest things, and his machines can be beyond deadly. Perry now admits that Heinz is a high-level threat, but somehow the man still seems safe to be around. Heinz is interesting, smart, kind, caring, dorky, clumsy, and considerate all in one.
That's why Perry worries when Heinz collapses mid-monologue. He quickly escapes the simple leg snare trap before running to his nemesis. Heinz is sleeping. Perry has seen the growing dark circles under his eyes these past few days.
Sighing, Perry heaves Heinz onto the couch before covering him with a blanket. He goes to exit the front door this time, thinking that his jet pack may wake the scientist. He stops when he sees little shoes at the front door.
Perry knows the shoes belong to Vanessa. His nemesis has never spoken about his daughter, but that's exactly how Perry knows she's his world. As nemeses, Heinz only tells him about the people he dislikes: the people who've wronged him. Vanessa has never been brought up because Heinz adores her.
It's late. It's "Linda-served-pie-hours-ago" late, and Heinz is passed out on the couch. Judging by the size of the little shoes, he would guess that Vanessa is around Candace's age. She'll need dinner.
Perry wars with himself for two minutes. Vanessa doesn't know him, it's weird to eat something that a stranger made. Then again, maybe Heinz talks about him? No, how do you explain this? "Oh yeah sweetie, I'm evil and I do evil things. The guy that beats your dad is actually good, don't mind the terrifying bruises he gave me." Just no. Heinz is also passed out and Perry doesn't know if he'll wake up tonight, will his daughter get scared? That's it, he's making her dinner.
Perry storms off to raid the fridge, only to find it full of junk. Heinz lets his daughter eat this garbage? Whatever, he has no right to tell his nemesis how to raise a kid but since he's "in charge" by default, he's gonna make sure she has the option of healthy food.
The agent walks to the produce store a block away to purchase salad ingredients. He makes an aesthetically pleasing and healthy salad before covering it with plastic wrap and leaving it in the fridge for Vanessa.
Before leaving Perry leaves three notes in the house, one is next to Heinz on the coffee table, one is on the salad to label it, and the other is on Heinz's undestroyed -inator. Perry admires his work before leaving to see his family. He doesn't know it yet, but he'll eventually consider Heinz and Vanessa as part of his family.
