Following my AU for the MLP:FiM universe where there are multiple kinds of changelings ('prep bugs' and 'goth bugs'), Cipher Stream is a changeling that never turned bright and colorful. He's spent so much of his life hiding this side of him, developing so much fear, anxiety, paranoia, that whenever he thinks he's been found out he panics. A lot.

I make my purple boy have a panic attack and turn into a buggy.
