Aunt Heidi

Aunt Heidi (Heidi Popkiss) is the sister of Professor Popkiss, who co-designed and built Supercar (with his friend and colleague, Dr. Horatio Beaker).

She is the legal guardian of Zizi, a young French girl; and, like her brother Rudolph, she enjoys cooking!

She appears in the second-series episodes Precious Cargo and The Day That Time Stood Still.

She was voiced by Sylvia Anderson.
