Captain Underpants and the Revolting Revenge of the Radioactive Robo-Boxers[]

George and Harold snap Nasty Old Mr. Krupp into Old Captain Underpants to save younger Nasty Mr Krupp "dressed as Captain Underpants from being beaten up by Slightly Younger Tiny Tippy" As soon as George and Harold snap wounded nasty Mr Krupp into Captain Underpants for the last time, Old Captain Underpants with his younger self team up and fight Slightly Younger Tiny Tippy, together and win.

After Slightly Younger Tiny Tippy dies in another time line, Old Captain Underpants is ordered to gather his clothes and fly back into his office, get dressed, and wash his face with water, turning him back into his nasty old self again.
