Iota is a small letter that falls into the Tearaway world at the beginning of the game. Pieces of paper then surround him, and become parts of his body. This is when he wakes up, and the adventure begins.
Iota is able to run as fast as a Wendigo, and can also walk on a glue path on a wall. He can carry and throw certain balls, he can turn into a ball and roll, as well as jump small distances after losing his resistance to You's commands and can ride a Rideable Pig just like his fellow letter Atoi. Iota can utilize the Squeeze Box to blow away enemies or pull them in.
- Iota cannot talk.
