What is your favorite psionic creature?

The 21st day of #30DaysofDarkSun is here and the question is "What is your favorite psionic creature?"

This one is really tough. There are so many great creatures on Athas that are psionically powerful and interesting. However, I think I have to go with.....Player Characters! The fact that every PC had a Wild Talent made them very unpredictable and gave them a reason to have survived to the fabled 3rd level to become a PC. Many times in creating PCs or NPCs that had a Wild Talent, the psionic power would become a defining trait of their character and could be woven into their backstory to explain why they became an adventurer and often lead to amazing stories during adventures.
