When Bob visits Edna to get his old super suit patched up in "The Incredibles", she is inspired to create new suits for the entire family, including Jack-Jack even though he has not yet exhibited any powers. She returns in "Incredibles 2", offering to babysit Jack-Jack for an exhausted Bob, and upgrades Jack-Jack's suit with sensors that allow the family to track him and curb his newly manifested powers via remote control. The time she spends looking after Jack-Jack is the focus of the short "Auntie Edna".
