Although Edna Mode did not know what powers Jack-Jack might develop, she covered various possibilities by making him a fireproof and bulletproof blanket sleeper-like jumpsuit. Creator Brad Bird explains on the DVD that Jack-Jack's varied abilities are a metaphor for how young children have infinite possibilities ahead of them in life. He begins to manifest a broader range of powers during "Incredibles 2", inspiring Edna to upgrade his suit with sensors that allow his family to track him or rein in his powers via remote control.
