Professor/Principal Hans Rotwood[3][4] is the quaternary antagonist of the animated television show American Dragon: Jake Long. He is voiced by Paul Rugg.


Old School Training (25)

Hans Rotwood in Season One

He used to be a famous professor until his theories on magical creatures humiliated him in front of his peers; destroyed his career as a scientific researcher; got him fired from his job at Hoboken Science Institute; finally reducing him to teaching at Millard Fillmore Middle School. As a believer of magical creatures, he teaches a class on them, but due to completely incorrect facts, Jake is always confused and has low grades in the class.

Rotwood has a notable dislike of Jake, initially due to Jake's lack of respect. Rotwood eventually develops a suspicion of Jake and keeps a close eye on him.

Talents, Interests and Abilities

After the departure of Principal Dolores Derceto, Rotwood became Principal of Millard Fillmore Middle School in her place. He then worked to trick Jake into revealing himself as a dragon to him. He finally succeeded after a campaign to make Jake reveal his dragon form by humiliating him at school. While he finally gained personal proof, he was unable to obtain anything concrete enough to show others. However, in a brief truce, Jake gave him a personal look at the magical world by taking Rotwood to the Magus Bazaar where he was thoroughly delighted[5].

Although wishing to be famous for proving the existence of magical creatures, Rotwood appears to have a true affinity for them. During a trip inside Rotwood's dreams and memories, it is suggested he encountered a chimera as a baby, which may have been what started his life's interest in the magical world[6]. At Jake's graduation, the two seem to have put their differences aside as they shook hands.[7]


  • Rotwood: (To Jake) Unicorns. Oh, look a Pixie. Trolls! Leprechauns! Oh, this is the best birthday present anyone has ever given me. I can't stand it! (goes to a Troll) You are all so fascinating.
    Troll: (pushes Rotwood) Get away from me!
    Rotwood: (goes to a Wood Nymph) I am a lifelong fan.
    Wood Nymph: (yells at Rotwood) Back off! Back off, you!
    Rotwood: (goes to a Hag) Breath taking.
    Hag: (slaps Rotwood) STOP touching me!


  • As of Season 2, Rotwood is revealed to be 47 years old[5].
  • He is very similar to Denzel Crocker From The Fairly Odd Parents:
    • Both want to prove that magical beings exist.
      • Denzel Crocker proves that fairy godparents exist while Rotwood proves that magical creatures exist.
    • Both act as an antagonist to their respective students; Timmy Turner and Jake Long.
      • Mr. Crocker knows Timmy has fairy godparents while Rotwood had personal proof that Jake is a dragon.
