Villain Critique: Dr. Heinz Doofenshmirtz from Phineas and Ferb

Good morning, everyone. Sorry that it's been a long time since I've done Villain Critique. My laziness and being sidetracked got the better of me.

Anyway, here I am, again, with a new critique today. But before I do that, let's go over the rules:

First, if you haven't seen, read, played, or heard of any of these villains and/or the media that they appear in, there will be spoilers. You have been warned. Also, keep in mind that I haven't seen, heard of, and/or known a lot about every villain out there, so if you have a villain that you want to show me and I haven't known about him or her yet, please be sure to lend me some information through either reply or via PM.

Second, This is all just my personal opinion and you don't have to agree with me if you don't want to. Just please be nice, constructive, and considerate, especially when telling me why you disagree in the comments down below or via PM.

And finally, I don't just do movie or cartoon villains. I also do villains from video games, comics, television, and even fan-made, popular OCs.

So, let's get started with everybody's favorite, comedic, and tragic evil scientist: Dr. Heinz Doofenshmirtz.

Now, I'm a big fan of the Phineas and Ferb franchise. It was funny, heartfelt, action-packed, heartbreaking, and especially full of well-written songs and memorable characters. Three of my favorite characters in the series are Perry the Platypus/Agent P, Dr. Doofenshmirtz, and Isabella Garcia-Shapiro. But let's talk about the one in the middle and see why he's not only a well-written and sympathetic villain in the series, but one of the best villains and characters in Disney Cartoon history, at least in my opinion, shall we?

1. Design(s): Just like at least most of the other characters in the franchise, Doofenshmirtz' design was made to be simpler for kids to draw. And I think it works like a charm. His design elements, like his long nose, crooked smile, and black t-shirt with his iconic white lab coat, really show off his personality as the comedic, tragic, and German evil scientist that he's been throughout most of the series. It's great at communicating what he's about and is very expressive.
2. Personality: Like I've said before, Doofenshmirtz is very comedic. He may want to take over the Tri-State Area, but he's not exactly evil, at least not in the traditional sense. He's goofy, clueless, and overly-dramatic, but still very intelligent as he's able to build Inators that can do... pretty much anything. He's also very sympathetic and has a genuine good side. He cares about his daughter, Vanessa, very much and has a very friendly relationship with Perry despite them being nemesis.
3. Backstory:Oh boy. If there was an award ceremony for who had the most tragic childhood/backstories in history, Doofenshmirtz' would be among the highest, in my opinion. He's been abused, mistreated, and emotionally scarred for most of his entire life, especially during his childhood, all because of his uncaring, cruel, and sinister parents and goody-two-shoes brother. He was forced to be a literal lawn-gnome who wasn't allowed to eat, sleep, or even move for hours, possibly for days, and throughout the night. He was temporarily disowned by his parents and raised by ocelots. He lost his first and only childhood friend, Balloony. And neither of his parents never showed up for his actual birth. And that's just a few of them. It makes his actions more understandable and makes him more admirable that he's still an at least somewhat nice guy despite all that he's been through.
4. Abilities: Doofenshmirtz has built many iconic and nefarious inventions called Inators that can do pretty much anything from deflation, to inflation, to shrinking, to invisibility, and even dimensional-travel. He's also very durable as he's able to survive many things that would normally kill the average human.
5. Weaknesses: However, despite his intelligence, he does have a lack of common sense and can be very clueless, relatively harmless, and eccentric to a fault. Which can make it very hard to take him seriously despite even his more menacing Inators. He also will not hit girls.
6. Character Arc/Development: Doofenshmirtz has been through many battles, adventures, and even bonding moments with Perry/Agent P together. He's also been through a lot of trauma and pain throughout most of his life, but he still managed to persevere through all of it and keep an lighter attitude and even redeem himself into being a good guy in the end, thanks to his daughter, Vanessa.
7. Miscellaneous: Doofenshmirtz also has a great singing voice and voice in general and has at least some of the best songs in the series. He's also a really great dad, friend, and nemesis to have around despite his blunders.
8. Overall: Dan Povenmire has made such a great villain with an equally great mixture of sympathy, comedy, and evil-y, and even though the show itself is over, it's still going strong and I can't wait to see what the future holds for both it and this wonderful villain and character. You done good, Dan Povenmire. You done good.

Now, if you have a favorite villain (movies, cartoons, video games, etc.) that you want me to critique, let me know either in the comments down below or via PM. Also, be sure to give me some information of your villain if I don't know that much about them.

What do you think of both this critique and this villain? Do you like them both? If so, why or why not? Please let me know.

Have a fantastic day.
