Doofenshmirtz (1914)

Doofenshmirtz is probally the ancestor of the modern day Heinz Doofenshmirtz and a nemesis to the Perry the Platypus of 1914, and Ohio Flynn & Rhode-Island Fletcher.

Personality
Doofenshmirtz has so far displayed little of the child-like traits of Modern day Doofenshmirtz making him far less of a comic villian, and more of a serious one. Doofenshmirtz is also alot more calmer not reacting to the Abombible Snow Man's pressense and focus on Ohio and Rhode Island's instead.

Ohio Flynn & Rhode-Island Fletcher
Judging from Ohio's reconition it would seem that Doofenshmirtz had atleast one encounter prior to the events of Phineas and Ferb and the Temple of Juatchadoon

Perry the Platypus
Judging from the reconition of Doofenshmirtz to the Platypus, it would seem that they had at least one encouter prior to Phineas and ferb and the Temple of Juatchadoon however Ohio and Rhode-Island didn't seem to be aware of Perry's existance until the episode.

Isabella
Doofenshmirtz captured Isabella's mother, and forced her to aid him in getting the Amulet of Juatchadoon. Doofenshmirtz than double crossed her, and the two are on very bad terms.

Background Information

 * the Coat that Doofenshmirtz was wearing in 1914 is simular/the same to Heinz Doofenshmirtz's winter coat in the modern day.


 * It is asumed that Doofenshmirtz died after the Temple of Juatchadoon was destroyed, this would make him the second Alternate-Doofenshmirtz to die (presumibly assuming that Dr. Jekyll Doofenshmirtz was eaten) ("The monster of Phineas and Ferb-Stein")
