The Resistance movement was a group of Human-Controllers who escaped the Yeerks and found each other, forming a small anti-Yeerk resistance movement. They were lead by Hugo. Their symbol was that of a Hawk, which they spraypainted across the Animorphs' hometown. This attracted the attention of Tobias, who followed their clues and then met them in person, finding out their secret. They had a virtual reality device, which helped Tobias hear a message from Elfangor, revealing that he was Tobias' father. Soon afterward, their hideout was overrun by Controllers.
- This group only appears in the TV series.
