Deanna Thomas-Wilson is the Canadian born former Keeper of Earth and Heather's predecessor.
As a teenager, Deanna was certainly no pushover. She had little patience for people who irritated her and always stood up for what she believed in. However, she could often be short-tempered, rude and very mean, occasionally getting into physical fights. Nowadays, her temper has cooled down, but she still has a short fuse when it comes to people who irritate her.
