Stricklander (also known as Waltolomew "Walter" Strickler to humans and simply known as Strickler) is a major character in the Tales of Arcadia franchise. He appears as a normal high school teacher and fatherly figure to Jim Lake Jr. but is in fact, a changeling who has been implanted in Arcadia Oaks High School and working against the Trollhunters to bring back Gunmar the Black. However, he falls in love with Jim's mother, Barbara and changes his ways for her.
He is briefly the co-mentor of Jim Lake Jr. and close friends with Ms. Zelda Nomura.
Stricklander is initially a villain and tertiary antagonist of Part 1 of Trollhunters. However, in the second half of Part 1, he becomes the secondary antagonist until coming to Jim for help against Angor Rot. In the final moments of Part 1, Stricklander becomes an anti-hero. He is a minor protagonist in Part 2 of Trollhunters and a supporting protagonist in Part 3. He is also a minor character in 3Below and a supporting character in the feature film Trollhunters: Rise of the Titans.
Strickler is the first antagonist to reform in the last episode of Trollhunters.
He claims to be a good swimmer. (In Good Hands)
For unknown reasons, Strickler's wings were not mentioned at all in Part 1. However, it is possible they were hidden underneath his cape the whole time .
Jim once mentioned that he saw Strickler as a father figure until learning he was a changeling. However this relationship was later restored overtime and had a chance to restart it.
In the new timeline, Jim sets Strickler with his mom earlier and seems more supportive of the "Stricklake" relationship, presumably in hopes he can be redeemed earlier.
