Callie was a former human who came across magical powers, allowing her to become a reptilian woman.
As a human, she was kind of shy and timid. This reptilian form is far from that. Boisterous, outgoing, and devious at times. But a playful devious. She might prank you with her magic.
However, with her magic, what she does for herself rarely goes beyond being reptilian. This is especially evident in her right eye. She is legally blind in it, and she covered it with her hair. She refuses to fix it as to not "lose herself". Regardless of the way she acts she is still a bit timid.
