The Incredibles - Ending Explained

The film's major twist is that the villain Syndrome is actually Buddy Pine, the young fan Bob rejected in the prologue. Another key revelation is that the baby, Jack-Jack, who was thought to be powerless, actually possesses a multitude of unstable powers (shapeshifting, fire, laser eyes), which he uses to defeat Syndrome in the final abduction attempt. The film ends with the family accepting their identities, donning their masks in public to fight a new villain, the Underminer, signifying their return to heroism.

A prominent critical reading views the film through an Ayn Rand / Objectivist lens, arguing that it champions a 'Ubermensch' philosophy where the naturally gifted ('Supers') are held back by a jealous, mediocre society and government bureaucracy. Critics point to Syndrome representing the danger of 'democratizing' power ('If everyone is super, no one is'). However, others interpret it as a rejection of toxic masculinity and isolationism, noting that Bob only succeeds when he accepts help and values his family over his individual ego.
