Website Info
''Molded into an evil dictator by a single unfortunate childhood incident, Dr. Doofenshmirtz has one goal and one goal only; to enforce his dominion over the entire Tri-State Area. He has successfully unleashed his full potential of evil with the help of his cyborg army led by Perry the Platyborg.''

Early life
Unlike his 1st Dimension counterpart, Doofenshmirtz apparently had a perfect childhood. This childhood is never specified, other than the fact that he lost his left eye (which he now keeps in a small pouch) for unspecified reasons and had a beloved toy train called Choo-Choo. One day, he lost Choo-Choo, and it took a toll on his emotions, molding him into a malevolent villain. A maximum of five years prior to Across the 2nd Dimension, he somehow defeated Perry (whether or not it was because they were at odds with one another because Perry was a secret agent out to stop him is unclear) and transformed him into the Platyborg, which he commanded to lead an army of Norm bots to invade The Tri-State Area, conquer it, and thrust it into a reign in which all civilians must wear Dooferalls and play Doofopoly. At some point, one of Danville's civilians decided that enough was enough and she founded The Resistance, an organization bent on ending his rule once and for all. He and The Resistance have been at odds ever since, paralleling the life-long feud between the 1st Dimension's Perry and Dr. Doofenshmirtz.

Personality
As the ruler of the 2nd Dimension's Tri-State Area, Doofenshmirtz is actually more evil than his 1st Dimension self. Tyrannical, cunning, and intelligent, he immediately seizes any chances available to gain more power; when his 1st Dimension self comes to the 2nd Dimension, he decides that he should "give it a try" and conquer the 1st Dimension's Tri-State Area, although this was more of a way to see if said Tri-State Area was more difficult to conquer than the 2nd Dimension's.

Doofenshmirtz is actually also willing to eliminate those that pose as some significant obstacle in his plan (or at least those that disappointed him in some way), once ordering the extermination of the 1st Dimension selves of Phineas and Ferb to expose the 1st Dimension Perry's secret identity. He then ordered the feeding of the same Phineas, Ferb, and Perry, along with the 1st Dimension selves of Candace and even Doofenshmirtz to a Goozim, Phineas and Ferb for refusing to reconstruct the Otherdimensionator, Perry for failing as leverage against Phineas and Ferb, Candace for being incidental, and Doofenshmirtz for just being plain annoying to him. However, this plan failed. He would later attempt to strike down Phineas, albeit with a baseball launcher, when he begins to stop his plans, but he was foiled by Perry. He then attempted to crush Phineas, Ferb, and Perry with a fist from his giant robot shortly afterwards, but he was interrupted by the 1st Dimension Doofenshmirtz.

Despite him being a darker and more sinister version of the 1st Dimension Doofenshmirtz, he still has his flaws and lighter sides, like his 1st Dimension counterpart: he would burst out into monologues; he sometimes slips into a goofy personality, very briefly so; and he, in an act of irony, is revealed to have mindlessly included a self-destruct device on his Norm bots. Additionally, his good side immediately returned when Doofenshmirtz loaned over his own Choo-Choo, causing him to change his mind in taking over the 1st Dimension Tri-State Area and end his reign in the 2nd Dimension Tri-State Area.

Physical Appearance
Doofenshmirtz is possesses the same build as his 1st Dimension counterpart. However, he has a slightly different hairstyle; wears a black buttoned-up labcoat, gray pants, black boots, gray gloves, and an eyepatch with a scar running over it (exactly how he came to have the eyepatch or the scar is unknown); he doesn't slouch; and he has the ability to grow facial hair, something that the 1st Dimension Doofenshmirtz wanted to have ("Crack That Whip").

Perry the Platypus
Perry, a.k.a. "The Platyborg", is Doofenshmirtz's second-in-command and Norm bot general. He usually makes commands to the Platyborg, but other than that, nothing on their relationship has been revealed, nor their past in which Perry was (allegedly) a secret agent.

Dr. Doofenshmirtz
When he and the 1st Dimension Doofenshmirtz meet, they initially become friends and team up to capture Perry and force his owners into reconstructing the Otherdimensionator. However, when he realizes that the 1st Dimension Doofenshmirtz is more idiotic than him, Doofenshmirtz turns against him and attempts to feed him to his pet Goozim along with Perry, Phineas, Ferb, and Candace, but all five escape. When the 1st Dimension Doofenshmirtz hands over his own Choo-Choo, Doofenshmirtz changes his ways and makes up with his 1st Dimension counterpart.

Candace Flynn and The Resistance
Candace and The Resistance are Doofenshmirtz's nemeses, who have been at odds against each other for a maximum of five years. Not much about this relationship is known, but it appears to parallel the feud between the 1st Dimension's Perry and Doofenshmirtz.

Background Information

 * It is considered irony that Doofenshmirtz never went through any of the 1st Dimension Doofenshmirtz's unfortunate childhood events, such as being forced to dress up as a lawn gnome, being disowned by his parents and being raised by ocelots, etc., and that it only took the loss of his toy train to reshape him into the villain he is now.
 * Doofenshmirtz is most likely not the husband of a 2nd Dimension counterpart of Charlene Doofenshmirtz, and therefore not the father of a 2nd Dimension Vanessa Doofenshmirtz, as none of the two are either seen or mentioned in the film; however, this serves as an obstacle for the continuation of Doofenshmirtz's reign after he passes away.
