"Upon an evil winter's heart, the heavy hand of regret infrequently alights. The malevolent path is one trod without the cumbersome shackles of sentimental introspec--"
— An excerpt from Paragraph 4 of Inside an Evil Mind: The Dr. Wexler Story (As quoted by Perry the Platypus using a CD player[src]

Dr. Lloyd Wexler is the evil mad scientist and the hero of Heinz Doofenshmirtz.


Dr. Lloyd Wexler was born on January 8th, 1950[2]. He is an evil scientist, whom Heinz Doofenshmirtz has looked up to for a long time.

At one point, he was captured by The Agency so Perry the Platypus could impersonate as him and investigate that year's Evil-Con. Wexler was presumably returned after the Evil-Con, but it was not shown ("A Hard Day's Knight").

Perry lip-synchs to a recording of Dr. Wexler reading from paragraph four of his autobiography, Inside an Evil Mind: The Dr. Wexler Story.

Background Information

Dr. Wexler's ID card

Wexler's evil ID.

  • Wexler is 5'10.
  • Wexler weighs 270 lbs.
  • Spends in his underwear in most of the episode.
  • Wexler's evil ID card expired April 2009, and it also indicates that he is clearly "not a platypus".
  • He bears an interesting resemblance to Professor Norton Nimnul from Chip 'n Dale Rescue Rangers.
  • Dr. Wexler's voice, as heard on the audiobook Agent P plays at Evil-Con, is similar to that of Professor Calamitous from The Adventures of Jimmy Neutron. This makes it very likely that Tim Curry is the actor for this character.
  • Since Dr. Wexler appears to be a British character, it's possible that he was born on the 1st of August instead of the 8th of January; this is due to the little endian form of dating, which is employed in the UK.
  • Doofenshmirtz mentioned him making a ransom note so this may hint he has kidnapped someone in the past.
