Patricia (パトリシア) is the queen of Radaxian and mother of Alex Kidd and Egle. When Janken the Great invaded Radaxian, it was thought that Patricia was taken away. After Janken is defeated in his castle, Princess Lora tells Alex Kidd that she was already in a safe place.

It is unknown why King Thunder left Radaxian without Patricia, or why he didn't get her back to Paperock. Its is probably due to his wishing of being unnoticed.
