With all other options exhausted, Perry the Platypus finally realizes what Major Monogram meant when he said there was only one way for the OWCA agents to emerge victorious. So Perry swipes the Infinity Stones from an incredulous Dr. Doofenshmirtz, uses his Platyborg hand's nano-technology to form a new gauntlet-inator, and snaps his tiny platypus fingers, wiping out Dr. Doofenshmirtz and his armies but causing fatal damage to himself in the process.
