He makes a bunch of stupid inators, just like Weegee, and he always is foiled by Perry. He is native to the country of Drusselstein. Head of Doofenshmirtz Evil Inc., he lives on one of the top floors of the building. Other peeps live there.
Neither of Doof's parents showed up for his birth. Neither of his parents even CARED about him. He shared his abnormal childhood with Perry by backstories.
When he was in college, he devoted to a life of poetry. Here is one of his not-so-masterfulpieces.
The movies are black
The TV is gray
The horses are running
Please bring me some food.
Now I've got food
A couple of grapes
This poem is over
I've also got crepes. (The last 4 lines were by me) :-D
Well, Doof fails at all his plans. Ha ha ha ha ha ha ha ha ha
