Even after the Banes demolish Bruce by breaking his back in multiple places and numerous other bones, the suit takes over and eliminates the entire gang with extreme measures. In Bruce's last case, he used the X7 suit to defeat a cult of venom-using thugs who call themselves the Banes. He did this with a ruthlessly intelligent artificial intelligence that could override the user's pain receptors and allow them to tank incomprehensible amounts of punishment. Once he realized Batman was on the verge of failing for good, he designed a suit with one goal in mind: to succeed at ANY cost.
In the world of Batman Beyond, Bruce Wayne kept on as Batman well into his golden years, and it eventually caught up to him. The X7's most notable appearance plays out through Batman Beyond #6-11, by Dan Jurgens, Bernard Chang and Marcelo Maiolo. The X7 prototype was seldomly used, but the times it's been pulled out of the vault had grand implications on the Bat-Family. And while his patented black and red suit is one of the most recognizable and powerful suits in Batman's considerable wardrobe, it's still dwarfed in raw power by a special prototype built by Bruce Wayne in the twilight of his career. In both the DC Animated Universe and the comics it inspired, Batman Beyond showcases the most technologically advanced Batman we've ever seen.
