it took me years to realize the Incredibles family suit is combination of Mr. Incredible and Elastigirl suits
Mr.Incredible has a big i
Elastigirl has a her logo in a small circle
The Incredibles have an i in a small circle
which means Edna Mode thought about bullet proofing, fire proofing and also making the image of a family that has the legacy of both Elastigirl and Mr.Incredible meaning
