Whisper is one of the main protagonists in the IDW series. She is the only remaining member of the original Diamondcutters, and she is an excellent soldier with many abilities. Her and her team of Wispons tend to be loners, and have difficulty trusting people. 

Personality: In the past, Whisper was excitable and bubbly, much like Tangle. Even then, she still took her missions and fights seriously. Whisper also used to be more outspoken, eloquent, and joyful, but due to the trauma that Eggman and Mimic had caused her by ensuring the demise of her friends, she grew much more silent and reserved. Since then, she has been more shy, cautious, and distrustful of others, preferring to be out of the spotlight and in hiding.
